L ON THE CONTROL INSECTS AND FUNGI. Copyright, 1917, By Fred Reinleiii, Portland, Oregon. Circular No. 151. July 20, 1917. ERATTA: <^'^ ^"^ Several unfavorable conditions, lar^'ely ■ , ; -rd by the war, combined to make it impracticable for me to reaa proof of this Circular. The result is, it contains considerable typograph- ical errors. Taking the Circular as a whole I find that these errors do not lead to any misunderstanding. On page 12, par- agraph 3, mention is made of an 'insect, admittedly extremely injurious.' By this is meant the pear thrips. On page 32 you find 'The Cain Borer' for 'The Cane Borer,' also below, on same page, 'sweet and sour-sweet' for 'sweet and non- sweet.' On page 35 you find 'large pole pines' for 'lodge pole pine.' On page 36 'broadly impossible' for 'blandly impossi- ble.' On page 37 'millions of feet' for 'billions of feet.' also preventative war' for 'preventive work. ' On page 39 'left us available places' for 'left no available places.' On page 34 it reads 'these savings' for 'these sow- ings.' Quotation marks have been left out in a number of places where they should have appeared. StP \2ldi7 ON CONTROL OF INSECTS AND FUNGI. Copyright 1917. By FRED REINLEIN, Portland, Oregon. Circular No. 151. July 20, 1917. Inasmuch as anything: new pertaining to agriculture cannot be satisfactorily introduced unless it can be shown that the mat- ter had been submitted to the Department of Agriculture for ex- amination, and had there been approved; it follow^s that it is the duty of the Bureau of Ethnology to define its position in regard to anything new that has bearing on the control of insects. I have been wanting the Bureau of Ethnology to define its position on new matter for 19 years past. What the Bureau at present is wanted to act on is set forth in my Circulars No. 148 to 150. There was no action of any kind whatever taken on my Circular No. 148, nor on those preceeding, as far back as No. 141. This was due, as explained in my Circular No. 150. to the failure of the Chairmen of the Congressional Committees on Ag- riculture to do their duty. With the appearance of my Circular No. 149 Senator Geo. E. Chamberlain of Oregon was asked to see to it that the Bureau either admit that I am right, or else show wherein I am wrong. As explained on page 18 of my Circular No. 150, Mr. Chamber- lain w^as fair enough to give me a look at the tw^o replies he re- ceived, which showed that the Bureau had done neither of the two, but had handed him out a bundle of lies in each case. Since Senator Chamberlain did not see to it that he got any desired information on any given point the matter was taken up w^ith the congressman from the district I then lived in, Hon. W. C. Hawley, as stated on page 19, of my Circular No. 150. He too, got first of all, a bundle of lies. Circular No. 150 was meanwhile gotten out to explain in handy form just what the Bureau w^as most wanted to take action upon. Mr. Hawley was asked to see to it that action was taken, (2) J and here is the essence of the reply he ^ot. "The suggestions made by Mr. Reinlein in this circular (150) have been examined by the experts of this Bureau, who are of the opinion that they are impractical." It is all a lie. If the experts had investigated the suggestions they would not now want to hand out an opinion, for they would then positively say wh^t their investigation had shown. An op- inion, as used in law, is the formal decision of a judge or coun- celor; not a mere claim as is the statement of the Entomologist: but the claim is substantiated by giving the reasons upon which the claim is based. Members of Congress can be expected to know this. For an illustration of how the Entomologist's claim works out, take the description of the control of the range caterpillar, as given on pages i to 3, of my Circular No. 150. The Bureau has virtually nothing in the way of control that is tangible. They expect to control the caterpillar b}^ natural enemies — parasites and predatory insects, saying the value of the crop is too small to allow of the use of artificial means, in the sense this form is generally understood, which is true. Having nothing better to offer than the development of par- asites and predatory insects, and expecting this to solve the problem, or at least make this do to placate the population of the affected territory, is equal to claiming that it would be possible to control the codlingmoth or any other insect by this course a- lot^g. Man can merely assist in establishing natural enemies, which in turn are often decimated b_v enemies of their own. The means of control I suggested, first published in my Circular No. 146, issued Aug. 10, 1915, was calling for the systematic use of poultr3\ This suggestion was new; and the Entomologist, assisted by his experts, could, without an investigation, right then have handed out an opinion, showing why they arrived at that opin- ion. They did nothing of this kind. It had been shown to them that poultry could be made to attack the insect the year around, and it was showi to them at ©CLA478435 ' to fruit as it is approaching maturit_v might prove objectionable." Nothing is said as to what effect such continued poisoning would have on other insects, beneficial or neutral. "...When (the larva are) fully developed, w^hich usually re- quires a fortnight or three weeks, thev leave the fruit, w^hich has as a rule fallen several days previouslv, and enter the ground, seldom going deeper than one inch, depending on the nature of the soil. There they soon change to pupaeia and remain for 12 (i9) days to three weeks, depending: on the season — (p. 13).. Pupae were present under some of the deca3^ing peaches.,.. (p- 18). Thus poultry going about cultivated or wild vegetation in- infested, would simply have to pick on fallen fruit and thus either hnd larva within, or would, upon turning the fruit, often find pupae in full view, while those not feasible will be found by scratching, usually within an inch of that very point. Hence, economical control of this insect, or of the apple maggot, clearly calls for the widest possible use of poultry; this is simply making a systematic use of a domesticated kind of natural enemy. It (the Mediterranean fruit fly) is without question the most de- structive fruit pest on record in the w^orld toda3^"[p. 10] "The Argentine Ant," the Department tells Mr. Raker, '*is and insect which makes its nest in buildings.... Mr. Reinlein's plan is to use a plumber's torch to drive the ants, which he be- lieves Will carry their eggs and larva with them, iilto the open where it wmII be devoured by poultry." Every word is a lie. In Entomology Bulletin No. 122 you read: "At all the in- fested points the levee is found to be teeming with the ants and the batture itself is a constant breeding place... Here the ant colo- nies are found under every particle of drittwood and trash and during almost the entire year they are in attendance upon Coc- cidffi and Aphidida^ upon the willows." Ask the Departmeni what means they have to control the pest there or on crops, whereby attending lice and scale insects they make, it is estima- ted by the Department, on the average 5 specimens grow where, in their absence, one formerly was found before. The Department has nothing, absolutely nothing that is at all feasible. Just the same they want to deliberately fool the pub- lic by refusing to even admit that poultry raised in a systematic way to cope with such an enormous proposition has a chance to be of anv value. This when they, in Bulletin No. 122 state that the ants, when unmolested, very greatly interfere in the rais- ing of chicks, from which it follows that poultry is by nature an enemv of this pest. (20) In summer time the ants appear to do as little excavating as possible and seem to limit their efforts to excluding light and water, etc. [E. B. No. 122, p. 56.] In case of danger the work- ers' first instinct appears to be to remove the young [egg, larva, pupae] to a place of safety, and they readily sacrifice their own lives in order to accomplish this, [p, 40] Thus poultry, given a chance, will simply scratch the whole combination up and eat them up. For a beginning, however, to get a flock established at this work in a badly infested locality, I had pointed out that it might be of benefit to assist them some. One way would consist in accelerating their destrucfibn by the use of a blast torch, the kind shown on last page being a good type, and another way would consist in exposing quick acting poisoned sweets to the ants, which latter kills a limited number and drives the rest a- wa}^ from that particular place, giving poultry an undisturbed roosting place at night. It is manifest that there is much wild land that needs clear- ing, and a man wishing to rear poultry there should be welcomed b}' any owner to do so, and this would result in a self-sustaining well pajMug business, but if this work could not be made to pay for itself, it would have to be done just the same, since there is no more feasible wav known, and since without it the ants would be masters of the land, and stay masters. On page 1 1 of my Circular No. 150 I made reference to Ag- riculture Bulletin No. 377, giving the results of poison experi- ments to control the ants in houses. I showed on pages 11 to 14 that the most feasible means to obtain this consists in first of all giving the widest possible use to poultry outside, and then control the ants that have gone to nest in the houses b^' exposing quick acting poisons, which kills a few and drives the rest away quickly, stating expressly on page 13 that, "the use of poisoned sweets for control in houses is a necessity." No talk about an^' torch at all. You probabh' did not look for any such skillful ly- ing on the part of any Executive Department. "The experts of the Department are of the opinion that Mr. Reinlein's plans are entirely impracticable ", the Department winds up its yarn. Then just let them point out what plans de- scribed in this circular are impracticable. The Bureau makes no attempt to point out any means ot controlling- any invasion of cultivated crops by the ran^e cater- pillar. There are no means that can be pointed out- Neither they nor anyone else has any, except it be continued hand pick- ing-. How entirely futile the use of arsenicals would be can be gathered from a record of an outbreak of the yellow-bear cater- pillar given in Entomology Bulletin No. 82, part V. "judging from the results of these experiments, the arsenicals [applied to larva one-fourth to three-fourths grown, whereas the rang cater- pillar invades the ciop when nearly full grown, and is much larger] cannot be depended on to control. "[p. 66] "On reach- ing maturity the larva crawl under heaps of dead v\'eeds, tufts of grass.... In such quarters, which offer but slight protection the3^ construct frail cocoons There is no better method of fighting this species than to burn the weeds, grass etc., under which the pupae, [of the hibarnating brood,] find protection — " But there is a batter way: Poultr}^ given the run through such weeds, grass etc., will be able to get many of these pupae. Besides there is also a Spring brood with insects in the pupael stage during summer even still lighter protected- This course of control I had shown in previous circulars to be applicable in many other cases; especially in the control of certain timber in- sects. Whatever would burn is intended by nature to serve as pro- tection for the plants and tor the animal life subsisting under their protection, for providing breeding ground for ground dwell- ing birds, for increasing humus, retaining moisture, preventing erosion. Hence, such burning, often recommended by the Bureau in similar cases, cannot be too strongly condemned. Details for meeting the conditions that w^ill be encountered in carrying on poultry raising on a large scale in the range cat- erpillar territory are given in my Circular No. 146, pp. 9 to 14. I may add that, since the succulent plants in that area are usual- ly protected by strong spines, hence are not available for food, it is feasible, where they are available, to render daily a small (22) patch of them fit for nourishment, since they then provide both food and drink. This can be done through the use of a cactus burner or a hot air blast torch. A suitable t3^pe is shown on the last page of this Circular. A little grain scattered through that patch will attract all of the poultry to that spot. A supply of feed can as readily be provided on the range as anywhere, through the raising, in suitable valleys, of grains adapted to semi-arid areas. It is also practical to raise green feed for win- ter feeding, since at least the necessary breeding stock has to be carried over, by the raising of root crops, hardy and not hardy, and of vegetable plants, hardy in that territory, such as kale and Brussel sprouts. It is true that on page 12 of Bulletin No. 443 the Bureau claims cultivated cereal crops can be protected against the range caterpillar by spraying with a solution of one pound of powdered arsenate of lead to 50 gallons of water. But where are the tests to prove such an idiotic claim? The Bureau has found it neces- sary to recommend the use of 3 to 5 pounds of arsenate of lead to 50 gallons of w^ater for the destruction of newh^ hatched larva of the browntail moth, then what can you expect from a third and lifth strength solution of this where "the full grown larva frequenth' measures 2/2 inches in length, with the diameter of a man's index finger," (Bull. No. 85, p. 78) and w^here there is a continual stream coming in from the surrounding range? All the essential features of this, and much other matter be- sides, was explained to Mr. Raker by the use of marked and an- notated copies of my Circulars No. 146 to 150, and Mr. Raker was asked to hand this up to the Department for action, after having examined same. This he did, and he got the following reply: "The experts of this Department are of the opinion that Mr. Reinlein's plans are impractical. Apparently he is writing theoretically and without any first-hand knowledge of the insect concerned." Thus seeing that Mr. Raker was giving me a chance at making a defense, thev did not want to make any specific state- ment this time, and did expect Mr. Raker to let the matter rest upon their word that I am wrong, this when thev had been asked (23) to show why their previous letter had not been a bundle of lies. Naturall}^ Mr. Raker was asked, under date of April 13th, to prosecute the matter further. The far-reaching evils of erosion, their cause, their effect and t leir prevention, are describsd in Yearbood Separate No. 688, Farms, Forests, and Erosion. ''In general anvthingthat in- creases surface run-off, increases erosion... As a rule it is onl}' when the natural protective cover of forests, brush, grass and other plants is disturbed that serious and long continued erosion results"' (page 8) This is all new to the U. S. Entomologist and his experts, judging by what they write. A good sample ot what they write appeared recently in Agricultural Bulletin No. 416; The Red Spider on Cotton. Under heading of Remedial" Measures, you read on page 60: "Too much emphasis cannot be placed on the importance of ridding all field borders, ditch banks, terraces, etc. of all vegetation as far as possible — " Since cotton is only one of the 183 kinds of plants the red spider is known to feed on, employing this means in this and in other cases as advocated by the Bureau, for instance in the destruction of hibernating quarters for the chinch bug and the boll weevil, would, a perusal of Separate No. 688 will convince you, in the course of a comparative short time, turn the country into a desert. But aside from this I had shown throughout my Circulars No. 139 to 150 that such destruction of host plants is all wrong, and that the correct way of control consists in using the prefer- red host-pants for traps if they are to be used at all as a means of control. Since the Entomologist has been talking for about a year to the effect that I am wrong all around, without offering a particle of proof, I now prove them to be wrong once more, from the latest available evidence. On page 59 the authors state that the red spiders hibernate on several of the native and door-yard plants. "These hosts serve as sources of dispersion." Of course, what else could they do if not treated. "By destroying during winter and early spring (24) polkweed, Jerusalem oak, Jamestown weed, wild blackberr}^ w^ild geranium and other plants w^hich breed the pest, much good W'ill be done. This plan has been tested by the writer in several instances and has given complete immunity the following sea- son..." How these plants w^ere destroyed is not stated, proba- bly by burning and grubbing out. How^ about the next season? Has that work to be done over again every season? Of course w^ith first choice food plants rem^oved, the spiders will subsist on second, third and last choice plants. True, there is no practical wa}' to treat the plants, especially in out of the wa}^ places, ex- cept bv the w^a}' shown b}^ me as far back as 1898, b3' using the hot air blast, for which work the type of torch shown on last page is ver3^ suitable. These weeds are very often not on the owners land and,' anyway, if on waste places; should be left there except to give something better a chance, which in turn, will al- so harbor spiders, " In several instances of past severe annual infestation, violets" (probably the most favored winter food plant) "adjoin- ing fields have been thoroughly spra^^ed, wath the result that no red spider appeared in these fields..," Therefore 3^ou see if you only did treat these plants, thev would act as traps instead of sources of dispersion. And hot air furnished by a torch is ex- tremel}' cheap. Then again, since these plants ma^' not be on the owners land, he can keep his crop clean b}^ giving the plants near the source of infectation an occasional slight licking with a torch. With a practical means of controlling them on the crop at hand, there is some very good reason why the winter host plants should be left to themselves. Anything that kills the spiders kills also, as a rule, the natural enemies that are present. If the host plants are not treated, the}'- usualh^ become heavih^ infested and in turn-much sought after by natural enemies of the spider, causing the latter to increase in number. As the spider does not spread fast the use of a torch near the edge of the field makes it possible to absolutely control invasion. Again, taking cotton for a sample, this crop is attacked bv man^' other enemies. Suppose infestation by red spider had (25) been prevented through desiruction of host plants, but the cot- ton aphis were taking a hold. Repeated slight swift lickings with a torch are far the best and cheapest means ol control for this insect, and for aphis in general. On the other hand if noth- ing was done and red spider is invading the crop, the spider is thus being taken care of without extra work. In thus using a torch other larger insects present will be noticed, because they start to run when the,v feel the heat from the torch, when they can be killed. A large part of these would require hand picking or expensive contact insecticides. However, as will be shown later in discussing boll weevil control, poultry can be made to take care of these. It has been suggested to Mr. Raker that the matter had reached a stage when it would be speciallv opportune to have him call the attention of Mr. Lever, Chairman of the House Co;miittee on Agriculture, to it. As a result a letter was received from him May 8, containing the following: ..."it is my purpose to work with Mr. Raker or any other member of Congress that can and will give their assistance to this matter. The Department claims there is nothing in your idea, that you are wrong on all points." Thus Mr. Raker himself has found no evidence that I am wrong. On the contrary wants to be shown if there is an3«thing wrong about it. As for assistance, Mr. Lever is bound under the law to make the Department meet the issues, admit that I am right or else show what is wrong. That poultry raising as a means of controlling certain insects can be made to pay, and pay big, is pretty conclusively proven by evidence presented in Year-book Separate No. 700: The Thanksgiving Turkey. There on page 4 you find an account of successful turkey-ranching carried on "in the unsettled foot-hill region of California, and in certain sections of Arizona and other western states." If turke}^ can thus be profitably raised on a large scale in semi-arid, mountainous and very thinly settled sections, it is not clear why there should be any barrier to the systematic raising of chickens for both meat and eggs in the re- gion infested by the range caterpillar, or elsewhere over low- (26) priced land, for that matter. Beginnings with the melting of the snow after mid-winter, with insects then as 3^et completely inactive, and wild seeds scarce or absent, stems of grasses or weeds carrying the promi- nent egg-clusters of the hemilenca become the object of favorite attack by poultry. The insect is exposed to attack in this form as a rule, till June ist. The larval period in the largest number of cases extends from June ist to September ist— three months. That the poultry would effectively attack the insect in the larval form is proven in Ent. Bull. No. 85, p. 93: "On July 27, 1909 two robbins were seen, each with a hemilenca larva in its bill — By this date the majority of the larva are half grown. 'The birds fiew away with these..— apparently only of the smaller ones — as if intending to feed the caterpillars to their young." Thus if young birds can stand such young larva, it is safe to say that poultry can eat great numbers of the newly hatched and partly grown ones. And of course it is all a matter of the number of poultry on the job, whether any young larva would be left to grow big. There is nothing objectionable about the pupae. Skunks eat them greeily, although according to Chief Nelson of the Bureau of Biological Survey there is at present no evidence to show that they eat of the la^a, big or small. The adults are in plain uiew, resting on stems of grasses during the day, hence subject to attack. Egg- laying begins early in September, the species in this stage thus being subject to attack from then on till covered by snow. All this, with much" other matter, was in essence pointed out in my Circular No. 146, August 10, 1915- As the Entomologist has done nothing to satisfy himself as to the value of the evi- dence submitted, it will be v/ell to see what he says about birds, as enemies of the gips}'- and brown-tail moth. The latter of the two seems to be the w^orst of all important hairy caterpillars as regards the nature of the hairs.... The presence of caterpillars of the brown-tail moth in large numbers was actually unbearable on account of the poisoning... (Yearbook Separate No. 706. p, 2) Birds have some importance as enemies ~ of the gipsy-moth..., (27) pothunters..., have destroyed ^reat numbers of insectivorous birds. "Much of the increase in the number of the pest is attrib- uted to this." The caterpillars are preyed upon by the cuckoos, the Baltimore oriole, the yellow-throated vires and the blue jay." No destinction is here made between big and small caterpillars. "The moths are eaten by many birds," which is pretty good ev- idence that poultry would eat the moths of the range caterpillar, "and the eggs are eaten by several species." (Farm Bull. No. 275, page 15.) Again, "birds are important in checking the spread of the brown-tail moth. The caterpillar, like other hairy species, are not so much eaten by birds, except certain ones The moths... are preved upon to a great extent bv birds...." (Farm. Bull. No. 264, p. 18.) In regard to controlling such insects by means of natural enemies, the Entomologist says in Year-book Separate No. 704, page 9: '..,with other kinds,.,, which may exist in the egg stage, in a crawling larval stage, in a quiesent pupael stage, and as a flying adult, and which in their native homes are parasitized by whole series of species of parasites, some attacking them in one stage and some in another, and still. others in a third, it is not such a simple thing to introduce and acclimatize the parasites necessary to reconstitute the normal environment." And admit- tedly these parasites are subject at any time to decimation by hyper-parasites. Since the gipsy- and brown-tail moth are principally tree- feeding insects, they are usuallv out of reach of poultry. But the3^ are also often within reach. ..."it is a common habit with the larva (of the gipsy-moth) if they are disturbed, to spin silk- en threads which are attached to the trees, and in this way low- er themselves to the ground." (Yearbook Separate 706, page 5) Thus if a larva lowers itself a few times with poultry on the ground, the lowering is apt to be stopped for good. "...,Of course the brown-tail moth is carried in the caterpillar stage just as is the gipsy moth" (through their lowering on silken threads) ".upon vehicles of different kind passing through the infested re- gion and upon the persons of pedestrians as well,... (Farm Bull. 264, p. 13) "...small caterpillars [of the gipsy moth] immedi- U8) atel}^ after hatching may be blown long distances b}^ the wind. It has been proved that spread often occurs from a distance of from 12 to 20 miles in this way. [Y-Sepr. 706, page 5]. How to get rid of such scattered caterpillars the Bureau has not the slightest suggestion to offer. With the woods patrolled b}' poul- tr}^ for this and other pests, such as the brown-tail moth and the tussock-moth, this would keep the incipient pest in check. There is no means of extermination. The gipsy moth has been discovered as far west as Cleveland, O. Being an isolated case, everything humanel}' possible has been and is being done to stamp out the pest. But with 3'oung caterpillars having been blown 12 to 20 miles it cannot be told for years with any degree of certainty whether the attempts at extermination have been successful. "Over half a million dollars is the yearly expenditure [for the control of the gipsy moth] in Massachusetts at the present time." [Y. S. No. 706, p 8,] This is for work by towns and cities. In the woodlands the gipsy moth multiplies unhindered. It will be seen then, that unless the moth there is kept in check — and poultry is the only means in sight, the Bureau having nothing to offer but parasites and elimination of favorable food plants, such as oak — with the young capable of being blown for miles, there will be a constant reinfestation of cleared areas from this cause alone. This alone explains wh3' "it is inevitable that new colonies will be found from time to time outside the region now known to be invested,.." Thus in Dep. Agr. Bulletin No. 273, p. 18 it is estimated that the wind blows 210 million small larva annuall}^ into the ocean, and the number is probably much greater. It also emphasizes the necessit}^ of keeping this moth confined to New England territory if rapid and general spread over the United States is to be prevented." In Year-book Separate No. 704, p. 14, the U. S. Entomol- gist says: "On the whole, the work [of importing parasites of the gipsy- and brown-tail moth] has been very successful, and has helped in bringing about infinitelj'- better conditions in New England so far as these pests are concerned, and while it is prac- ticall}' certain that both the gipsy moth and brown-tail moth will (29) gfradually spread westward,- it is equally sure that the imported natural enemies will go with them, and that none of the long continued disastrous outbreaks which we saw in Massachusetts in the years prior to 1905 will occur further west." Let us see: "...A large part of the funds expended by towns and cities (in Massachusetts over half a million dollars a year) has been used for the protection oi shade and ornamental trees, it having been found impossible to carry on extensive work in w^oodlands, owing to the extreme cost of these operations. The beauty and attractiveness of most cities and residential sections depend on the trees...." (Y. S. No. 706 p. 10) That means that no funds were spent in woodlands except a little for experimen- tal work to find out that such work as is done in cities and residential sections involves their "extreme cost." The fact is the woodlands are not accessible to spraying rhachinery, and moreover represent far too low a valuation for this and all other artificial means of control, hence the insect there is left to breed unchecked. The "long continued disastrous outbreaks" have been and are existing there right along. "Enough pressure was brought to bear, however, in the fall of 1899, to cause the dis- continuance of State appropriations for the control of these in- sects... Matters became so serious in 1905 that work was resumed by the Commonwealth of Massachusetts..." Thus you see the "disastrous outbreaks" this humbugologist speaks about refer- red to conditions in towns and cities during a period when the state spent no money for 5 3'ears. The "infinitely better conditions" thus leaves the country at large without control, and as for work of the parasites, the insect does sufficiently well in spite of those to require the use of half a million dollars in towns and cities in Massachusetts a- lone. Poultr}' is a natural enemy of these and other insects, the only natural enemy that can be definitely controlled by man in its work, hence should for control in woodlands and farms, form the chief reliance in control. As for control in cities and residential sections this could be simplest secured through trapping the adults, in the case of the (so) g-ipsy moth of the male only. If woodlands and farms are con- trolled bj^ poiiltr3^ the number of brown-tail moths congregating in cities will correspondingly decrease, and thus greatly reduce the necessity for control there. If 3'ou will see to it that your Congressman uses his influence to see to it that action is taken on the matter in hand, I propose to show you how these moths can be trapped in vast numbers at surprisingly low cost. Until this is done you will have to look to the Secretary of Ag- riculture and his experts to show you how this trapping is done. Mr. A. S. Weiant, the author of Year-book Separate No. 700 was asked to tell what he knows about poultry as a means of controlling insect pests. He said to do this one should be an en- tomologist. Speaking of turkeys as largely occupying his at- tention, Mr. Weiant says: "As a means of keeping down grass- hoppers I can vouch tor them," There is no good reason why chickens should not answer as well. If so, this then simply proves that I was right when I said as far t)ack as in my Circu- lar No. 147, p. 15, that the correct means to control grass-hop- per outbreaks consists in judiciously using poultry: that since their stronghold is in the high, dry, rocky lands, dangerous in- vasions from that source can l>e prevented by having large flocks of poultry roam over these otherwise nearly idle lands. Over further on Mr. Weiant says: "Turkeys are naturally g:reat ran- gers and when given the opportunity can pick up the most of their food in meadows, grain fields, pastures, alfalfa fields, etc' Then why not raise enough of them to utilize all of the ex- isting opportunity? And why should chickens not do as well? I have noticed in the South that turkeys spend very little time in the cotton fields provided there are any pastures or grain fields to roam in. This is just what one would expect. Meadows, grainfields and woodlands offer far better feeding than cotton fields early in the season when poultry vrill be wanted to be kept in cotton fields on purpose as needed, the shortness of food sup- ply forcing them to hunt for weevils and attack fallen infested squares, pick up Argentine ant workers to keep them from fost- ering aphis infestation, during which they render far more val- ue in spite of requiring more grain and more attention, than they would l-)y consuming food where it is more plentiful. (3r) An insect must become quite common before it can form an appreciable portion of the food of (wild) birds..." Bui. 107, pa^e 2. If so, you cannot expect wild birds much to reduce the boll weevil, since being multi-brooded, reduction in number of hibernated adults is what is most needed, and a small number is admitedl_v easil\' able to produce an off-spring large enough to destroy the crop. The natural food of the turkey consists of insects, green vegetation, seeds and luits of various kinds." On page 4 of Year-book Separate No. 700 Mr. Weiant points out that tur- keys greatly relish acorns and that where these are plentiful but little grain need be used for fattening them in the fall, which fits in nicely wuth turke}' raising in the woodlands of New England, consisting as the^^ do largely of oak, as a means of keeping down gips}/- and brown-tail moth infestation. "Of the insects turkeys seem to prefer grass-hoppers to all others, but the}^ will also eat circkets, grubs and worms of various kinds, flies, but- ter-flies, moth, etc." There is no reason why they should not eat of the hemilenca moth (range caterpillar). These being on the grass-stems in plain view, simply waiting to be picked. As at that time, late fall, there are hardly any grass-hoppers, thev represent the food most easily available. "Some insects thev appear to let strictly alone. For example I have never seen a turkey eat an ant. a caterpillar, or a potato bug." Now ants may be too small, besides they might eat them in the form of larva and pupa, if not as adults. As to caterpillars, if fullv growm hairy ones are meant by this, it is correct enough. How^ about the small and spineless ones? Only careful tests can tell. As to what birds do in the way of destroying the Argentine ant you read on page 73, Ent. Bull. No. 122: "On one occasion Mr. G. A. Runner observed an English sparrow industriously picking up the Argentme workers from a trail which crossed a wude roadway at Baton Rouge. This habit is not, however, a common one with this bird." If this sparrow could get at noth- ing else, a condition that can be imposed on poultry, the habit would become common at once. "The flicker, or yellowhammer, Calaptes auratus, has of- (32) ten been seen industriously- digg-ing up shallow ant nests in lawns and grass plots, evidenth^ for the purpose of obtaining the pupa and larva, and should doubtless be credited with being- the most important natural enem}^ w^hich this ant has in the South.,." What the Entomologist was wanted to show^ all along was wh}^ poultr,v would not also dig up these nests. Speaking of poultry catching moths, it should be borne in mind that the adults of some borers most difficult to control are moths. Take the sugar cane moth borer. This insect is, in Ento- mology Circular No. 139, p. 2, conceded to do enormous dam- age. Figures there given place the loss on plant cane alone used in one factory in three years previous to 191 2 at $145,445. Since the U. S. Bureau of Entomology has published very little in regard to the life history of this insect, I asked Gover- nor Pleasant of Louisana for the favor to request his State Ex- periment Station to send me a copy of their Bulletin No. 70, second series: The Cain Borer. This was done. The remedies there given consist in substance in planting the cane as near as possible in the fall, burning all trash, and of culling cane and corn in the spring. The borers in the buried fall-planted cane are not able to emerge as adults through anything as thick as one-half inch of loose soil. "The windrowed areas should be systematically gleaned after removal'of cane for spring planting and all pieces of cane destroyed by fire or carefully buried..." [p. 923] " all trash [cane tops] should when cut be so arranged upon the cane rows as to hasten drying and whenever dry should be fired " (p. 924) The borer's "only food in Louisana has been found to be sugar cane, corn, Johnson grass, Guinea corn, sorghum, (sweet and sour-sweet) and possibly two other large grasses." (page 927.) But to burn or bury all waste is a pretty big job, besides burning any kind of vegetation means a loss. The Department of Agriculture fathers the statement that "the burning of a wheat stubble deprives the land of as much fertility as the producing of five crops of < wheat." If so the main loss is sustained through the action of the fire upon the soil. (33) *'Ever_vbody [with but few exceptions] burns the trash — vet with this only known effort practiced alike in every commu- nity, the borer multiplies to a destructive extent in one section and is practically subdued in another." (p. 902) Thus you see the need for something better, or at least for some effective additional means of control. 'Tf fall planting on- ly be made... the enclosed borers must remain until the cane is scraped in the spring ajid the few which w^ill then escape would be hardly enough to produce much harm during the summer..." (page 904). Let us see: On page 925 is given the record of a cane cul- ling bee. 420 acres were culled in the early spring, filling 120 sacks, each having 333 borers, or a total of 39960, this makes a catch of 95, say 100 borers to the acre. A female lays on the av- erage 300 eggs. Thus one female emerging from every 3 acres of scraped cane might do all this damage. Suppose 10 infested stalks per acre of first brood were missed. This gives us live re- sulting females, at 300 eggs each, or 1500 borer of second brood during say, June-July. 750 females will result, at 300 eggs each you have 225,000 borers of the third brood during August-Sept- ember: and 3,375,000 per acre for the 4th brood during October- Nove Tiber. While such numbers do not occur, more likely be- cause ot cannibalism than of all other causes combined, it shows that the insect has the faculty to increase to such numbers as can subsist under such competition. "Corn is more succulent, more rapid in development and thus in the economy ot the borer assures the development of ma- ny more specimens than if cane were the only food plant of the first two broods..." (page 912). Infestation of young corn is shown to be about ten times heavier than cane. (p. 912) Investigations have shown that 87 per cent of the moths e- merge prior to April 15th. Moths come from the pupa cases at night and after expanding their wings remain hanging to some plant or other object during the entire following day. The second night mating takes place and a few eggs may be deposited.. The moths are not shy and unless vigorously disturbed will not take flight during the day..., (p. 910)- (34) Since windrowed areas produce the largest number of moths, a stand of young corn there, with the moths hanging on the plants can be made to serve as a trap, since, the poultry given access: the moths can be largely secured. In the past the advice given was that "...limited tracts of corn badly infested with the iDorer in close proximit\^ to cane should be completely destroyed to protect the cane crop from succeeding broods..." (p. 925-); now with poultry at work there is no need of reducing the acre- age of corn, or abandoning corn for a vear or more, as recorded on page 914 to have been foimd beneficial in preventing heavy infestation of cane. "...few if an}^ moths emerge during the colder months of winter. ..(p, 910) ...the m.oths w^hile existing in small numbers confine their attacks to the ends of the rows and to the ditch bank rows..." [p. 903]. This either means that the earliest e- merging adults have Vv^intered outside of the fields hidden, away under some heavy vegetation, or else it means that the insect has hibernated as larva on plants on the ditch bank and more adults have developed there early than did in the fields; or it means both. At any rate the thing to do is, instead of planting- no corn, to plant corn by preference in the ditch bank rows and as near as possible at the ends of the rows, and to protect also the interior cf the field by strips of corn, kept patrolled all through the season by po'ultry. It is obvious that there must be ahvays corn on hand that is young. To this end tvro crops of corn are grown on these strips, some corn, beginning on March ist. being planted at intervals of one month up to September ist. While harvesting of cane is going on and before there is frost, the borer, with corn present, planted August ist and September ist, will virtually confine oviposition to these savings. These should be left standing. A legume can and should be sown be- tween at the last cultivation. Stock may be admitted after frost and the whole thing must be plowed down nicely before the be- ginning of emergence, say before Match loth. If poultry be not used, it Vv'ill be readily seen that the nor- mal requirement of corn could not be produced without endan- gering the cane crop unless a great deal of care is used culling (35) the corn. It would not seem feasible to cull millet by hand, hence under the old system millet must be left out of the crop rotatian. As practicality all of the cane growing area is overrun by the Argentine ant, poultry is needed all through the summer to pick up the workers to prevent undue multiplication of the measly bug and of aphids. Besides there are numerous other insects af- fecting corn and cane, and other crops necessary^ to allow at least of some diversification, which poultry can be more or less successfully used to control. Another highlv injurious day-flying moth is the adult of the peach-tree borer, which deposits her eggs at the base of the trees. Poultry allowed to roam through the orchard with a view of keeping down insects in general, would secure a certain number of these, reducing the need for other means of control. A day-flying moth that does very similar work, ovipositing at the base of the trees, is the sequoia pitch moth. It is at pres- ent the most destructive insect to the large pole pines in certain parts of Montana. Poultry made to roam the woods in sufficient quantity for controling insects in general would increase the use of the land and to a certain extent keep this pest in check. In his report for 1916 the Entomologist makes the claim that tests are being carried on by the Bureau of Entomology that hold out the possibility of a chance of discovering successful methods of preventing the establishment and spread of the pine- shoot moth, and of the European pine-saw fly, both "introduced shortly before the plant quarantine act became operative." [p. 16]. The first named insect has been introduced, as stated in Agr. Bull. No. 170, as far back as 191 1, was found in 1914 in 20 localities in nine states, in one case, the work then being 3 years old. Both sexes are strong fliers, laying their eggs in the apical and other terminal buds of pine trees, thus offering not the slightest chance of extermination as explained in detail in my Circular No. 145 and 146. Yet even as late as this the Ento- mologist wants to humbug the people into believing that its es- tablishment can yet be prevented, when for means of control it has nothing but the removal and burning of the infestedshoots. (36) In the case of the European pine-saw fly, extermination is, if possible, even more broadly impossible. The adult is a fly. The eggs are laid in the needles on the tips of the trees. The in- sect was discovered in August 1914 in Connecticut. It has two broods, which means rapid dissemination. This insect, together with the larchworm, it was shown on pages 16 and 17 of my Circular No. 149, has been decribed rather minutely in the re- port of the Connecticut State Entomologist for 191 5. Mr. S. A. Robicer of the Bureaa of Entomology at Washington, is there quoted as saying that " it has a large number of host trees" [in Europe] "and would no doubt adapt itself readily to the conditions in America "[Rep. Conn. Ent. 1915, p. 119]. Thus extermination if attempted, would involve examination of pines and other conifers for many miles around the original in- festation means of extermination there are none. As to means of control. 'Tt is eivdent that Diprion simile is freely attacked here by American species of parasitic Hymenoptera and Diptera, but it is not known as 3'et whether any Europeean species were brought into this country in the cocoons of the sawfly". Other practical means, necessary when the parasites fail, the Ento- mologist has none. The use of poultry makes it possible to secure the larva as they spin down or fall down occassionally, or when they migrate over the ground to other trees. The larva being hairless should make choice eating for poultry. "In Europe raking up and destroying the leaves and other rubbish under the trees in the fall is recommeded to distroy the cocoon." [p. 123]. A far better way would be to have the cocoons scratched up and eaten by poultry. The larchsaw fly is single brooded, spends the winter in a cocoon beneath rubbish on the ground and thus can easily be controlled by poultry, besides the caterpillars are subject to at- tack when on the ground. This insect ''invariably chooses the young, green, terminal twig in which to insert the eggs., When the apical terminal shoot is affected... a permanent kink may be caused... It is an injury which cannot be prevented..." page 127. Poultry, by keeping the insect down to limited numbers will prevent the in- (37) sect from layinpr any great number oi eo-g-s into any one shoot, and thus prevent any great injury to apical shoots. This saw-fly "during several extensive outbreaks since 1880 has killed from 50 to 100 per cent of the mature larch over vast areas in the north-eastern United States and south-eastern Can- da.,. aggregating many millions of feet." (Rep. Conn. p. 60) The chief factors in the control of the larch saw-fly are its nat- ural enemies, which consist of birds, mammals, a large number of parasitic and predaceous insects, and a fungus disease." (Rep. Conn, Ent. p, 130). But since outbreaks do occur with this and many other insects of similar habits, why not use poul- try when and where it is needed? vSince the Entomologist talks about half of his time about what great good parasites, native and imported, are doing as the result of the work of his Bureau, it is well to see what the pine shoot moth has done in Europe in spite of its parasites, and in spite of continued preventative war against it... If the attack is slight, it results in the branching of the tree," (since, if uninfected, the moth selects the apical bud for oviposition) but if the attack is severe and continued for several 3'ears, as we have seen it, then hardly any bud is spared and the pines be- come stunted into miseral31e small bushes..." (Dept, of x\gr, Bui. No. 170, p. 2.) "It is reasonable to suppose that some of the native para- sites on some of the native species of Evetvia will in time also attack Evetvia buoliana (the imported pine shoot moth) in this countr}^ — in fact parasitized larva have already been observed — but these native parasites cannot be relied upon to keep in check their natural hosts, the American pine shoot moths, which spo- radically become ver\" abundant and ver}^ injurious, in spite of the parasites and presumably will be less effective in controlling the newly introduced host." (p. 9.) "None of these native spe- cies (of pine shoot moths) can, however, even with this advan- tage [of having two broods annually] be compared in destruct- iveness to the European species just introduced... "[p. 8] Since chiefh^ young trees are chosen for oviposition, I had shown in ray Circular No, 145, page 7, that the sensible thing (38) to do is to protect, if possible, the apical bud in some \va3' when the adults are about laying their eggs, the most feasible way ap- pearing to me to be the pouring of some semi-liquid cla}^ over the apical bud, causing thus the moths to oviposit on a side shoot, which serves just as well. I also described in my Circulars No. 145. 147 and 149, pages 13 to 15, how these moths and ether night flying insects might be. trapped. Virtually all this and more was shown in my Circular No. 145, June 7, 1915, The Chairman of the Congressional Commit- tees on Agriculture^ Senator Thomas P. Gore and Representa- tive Asbury t . Lever were urged to have the U. S. Entomolo- gist either admit this to be correct, or else show why it should not be correct. Pouring semi-liquid clay over the apical bud ei- ther protects it or it does not protect it. "Early in August [in Europe) the eggs are laid singlj^ on the nevv' buds of the next years growth..." page 5. The adult will not of course, oviposit on hardened clay, when she has plenty of side shoots' serving fully as well. The Chairmen mentioned therefore should have forced the Entomologist to define his position. And this applies to all issues involved. Protecting the apical bud b}' an application of semi-liquid clay ma3^ be a simple enough idea. On thS other hand this insect "has been the subject of much stud^^ and of an extensive litera- ture from the time it was first described b^^ Schiffermnller in 1776 to the present day." The U. S. Entomologist frankly savs his Bureau is the best thing of the kind on earth. The fact re- mains, no one has pointed out this simple idea before; and now the Entomologist wants to pretend to be unable to see any good in it. And Messrs. Gore and Lever thus far, have wanted me to be hanged on that pretense. The apparatus shown on last page was designed with a view to meet the needs for an apparatus, that v/ill enable the man having a limited am.ount of vegetation, ranging in size from big trees down to grasses, to keep same free of insects and fungi. In a few cases, with the codling moth for instance, the proper use of arsnicals is the best thing at present known, but in the case of all sucking insects, and in any case vv^here poison is (39) for one reason or another not sa.tistactor_v ag^ainst bitini^" insects, with the exception of where the^^ can be controlled by poultry, or by trap crops, or by the torch used as a trap at night, the use of heat is far preferable to emplo^ving the contact insecticides now officialb/ recommended. It may be well to mention here that now flour mills and other buildings infested by insects are being fitted, as the best means known for control, with heating apparatus of such capac- ity that insects may be killed simply by giving so much heat that they will die purely because of high temperature, doing a- wa_v w^ith the many objections incident to using poisonous gases. The use of heat from a torch, was first described b^^ me in in 1898 and was first used b:v me in 1896 as a means of controll- ing the harlequin cabbage bug. In his report for 19 16 the Ento- mologist on page 18 says: ' ...Such remedies as trap-crop plant- ing and the destruction of the bugs with special burners are a- mong the most successful," in combating the harlequin bug. As for the trap crops, I had shown as far back as 1898 the adult bugs congregate on the tassels of sweet corn. More recently I have showm that by seemg to it to have at all times some cruci- ferous plant going to seed, the bugs will congregate on the seed- stalks and can be kept dowm by poultry, doing away with the use of heat, special or otherwise. But old or new, according to the Entomologist I am wrong either way. The adult harlequin bug lays her eggs on the underside of the leaves of cruciferous plants^ which leaves are mostly invert- ed spoonshaped; hence the 3^oung bugs usually cannot be seen without moving the leaf. Because of this the simplest means of control consists in concentrating the adults in plain view upon tassels of sweet corn or seedstalks of cruciferous plants. They then can be picked off by hand or by the use of poultr3^ On page ly of his report the Entomologist speaks about the control of the spinach aphis by lady beetles in the truck district of tidewater Virginia. He says "the extensive cutting down of trees and removal of underbrush for planting of truck crops left us available places for the ladybirds to hibernate..." Then how (4o) cjoes he expect these ladybirds to become and stay plentiful in the fields, since, moreover, they go to feed on lice on most of the crops and since all these crops need treatment as to insects and fungi, which treatment of necessity also kills the ladybugs. He says the plants cannot be reached, even with an underspray. I claim there is an "underspray" that reaches them, that is, reaches the lice hidden in the hollows of the inverted spoon- shaped leaves, especially when the plant is growing nicely in the spring. And this sprav consists in the use of heat as ap- plied by a torch. Some kind of knapsacktype torch is the thing to use and the essential feature in its use is to use it early, oft- en, and swiftly, letting the heat blow slantways upon the ground a few inches from the plants as they are approached. The heat waves will then roll in between the leaves. Without thus controlling the aphids, on the spinach, this crop will act as a winter host on a large scale for this and var- ious other kinds of aphids, resulting in abnormally heavy in- festation of succeeding crops. The special features of the apparatus shown consists in that the handle of the pistonrod of the pump located in the center serves also as a hook, making it possible, after remoying the shoulderstrap, to hook the apparatus from branch to branch in a tree. This does very well with the man having but few trees, making him independent in his work, since the official recom- mendations call for something else in many dilierent cases. For big trees in large numbers. I have described on pages II to 13 of my Circular No. 147 how suitable apparatus furnish- ing heat can be gotton up. Heat thus applied is far the best means to destroy the stem mothers of aphids and the adult pcarthrips as they congregate upon the bursting buds of fruit trees and fruit bushes. I had also shown how apparatus applying heat to lowgrow- ing vegetation, such as oats infested with the spring grain aphis, can be constructed, using, if desired, as far as practicable fit- tings from the outfit used for orchard work. (4i) The sprinii- grain aphis is usually held in check by natural enemies — for details see Enr. Circular Xo. 93, Revised. The natural enemies rather often fail. The latest occurrence was rii^^ht in 1916, as recorded on page 12 of the report. On pages 12 and 13 of my circular No. 144 I had shown at some length that the Entomologist has no tangible means of control. The use of heat does destroy the pest and should come into effect as soon as the danger of an outbreak becomes apparent. The Reinlein Knapsack Gasoline Torch Pat.
