See your county Extension adviser in agriculture for information. Livestock producers must manage insect pests to attain maximum production. Flies, lice, mites, ticks, and grubs irritate animals and some suck their blood. This reduces meat, milk, and egg production. On occasion, individual animals have been killed by attacks of large numbers of pests like horse flies, lice, and mites. Several of these pests transmit diseases from animal to animal. Losses from pests each year cost Illinois farmers millions of dollars. A livestock producer does not need to share his profits with insects — they can be managed effectively. Insect pest management programs, which include the wise selection of cultural, mechanical, biological, and chemical methods, are suggested for the major insect pests of livestock and livestock barns. Insecticides are still the most efficient means of managing most insect problems. Only the safest, most effective insecticides are suggested for each specific insect on each type of livestock. Other insecticides that may have label approval for use on live- stock are not included because they are less effective or more toxic or present potential residue problems. Blank spaces in the table of limitations (page 4) mean we do not suggest the insecticide for that specific use in Illinois. In using insecticides read the label and follow instruc- tions. Do not exceed the rates suggested; observe the in- terval between application and slaughter and apply only to those animals for which use has been approved. Keep a record of the insecticide used, trade name, percentage of active ingredients, dilution, rate of application, and dates of application. If you are ever questioned, you have the records. Most of the insecticides are suggested for use as emul- sion concentrates since these are the easiest formulations to handle. Wettable powders can be substituted if the finished spray is well agitated. Chemical names in these tables may be unfamiliar to you. These names are the common coined chemical names and are not capitalized. Trade names are capitalized. In the table of limitations (page 4) common names are listed first. If the trade name is more commonly used, it is listed in parentheses after the common name. In the tables of suggested insecticides on pages 2 and 3, only the common name is used if there is one. In case of question, refer to the table of limitations. These suggestions are printed annually. Always use the current year's issue. Labels may be cancelled and a product removed from the market at any time. New labels may be granted. We attempted to anticipate any further label changes, but there may be an occasional change. Check with your county Extension adviser if you are not sure about the insecticide you plan to use. We will make announcements of label changes through the news media to keep you up to date. Insecticides are being classified for general use or re- stricted use by the U.S. Environmental Protection Agency. Only a few insecticides have been classified for restricted use at this time. None of the insecticides listed in this cir- cidar Jmvc a restricted-use classification. A person wishing to use an insecticide classified for restricted use must be certified as a private or commercial pesticide applicator by the State of Illinois. Contact your county Extension ad- viser in agriculture for details on this program. The Illinois Department of Public Health has an- nounced it is illegal for dairymen to apply or store chlo- rinated-hydrocarbon insecticides — aldrin, chlordane, diel- drin, endrin, lindane, or heptachlor — on their farms, except for use in farm residences. Previously, use of DDT was prohibited except by permit from the Illinois Depart- ment of Agricidture or Public Health. Suggestions for use of insecticides are based on avail- able data. Rainfall, temperature, and many other factors affect efficiency of insecticides. Report the details of con- trol failures to us. These suggestions were prepared by entomologists of the University of Illinois College of Agriculture and the Illinois Natural History Survey. Leaflets describing the life history, biolog}', and habits of some of the insects mentioned can be obtained from offices of county Extension advisers or by writing to En- tomology Extension, 169 Natural Resources Building, Urbana, Illinois 61801. These are indicated by an NHE number in the tables. Obtain the following circulars on insect control from the Office of Agricultural Publications, 123 Mumford Hall, Urbana, Illinois 61801.

' Place cattle in barns or sheds to avoid attack by face flies, horn flies, horse flies, and deer flies. ' The same dosage of a water-base spray may be used. * Spray head, back, sides, belly, and legs carefully. Start treatments in late May or early June and continue to September. * Remove decaying straw, hay, manure, and feed from barns and lots, and spread to dry each week or cover manure pile with black plastic so stable fly breeding will be reduced. ' Add 2 pounds of detergent per 100 gallons of spray for better wetting effects. * Official scab eradication treatment used by the State Department of Agriculture. Involves two dippings 10-14 days apart. Isolate and treat incoming animals before introducing them into the flock. ' Stir the diazinon suspension frequently. ' Use on short-wooled sheep, no more than 6 weeks after shearing. h'^% \C\n^ GOATS, HORSES, CHICKENS, LIVESTOCK BARNS, AND SHEDS CD9
