second-generation problem cannot yet be determined. These second- generation moths 

 will deposit their eggs in a few fields between the late whorl and early silk stages. 



Moths are now emerging in southern Illinois , and will begin to emerge in central Il- 

 linois in about two to three weeks. However, it now appears that there will be enough 

 late corn that the moths will scatter their eggs in many fields, and perhaps not con- 

 centrate in a few. We will not know this until later. 



True armyworms can now be found in moderate numbers in a few weedy corn fields in 

 northern Illinois, as well as in no-till corn on sod. These worms also have many para- 

 site eggs on them and these parasites may help control later populations of true army- 

 worms, fall armyworms, cutworms, and perhaps similar pests. 



If control is necessary, carbaryl (Sevin) , toxaphene, malathion, and so on will be 

 helpful . 



FLY CONTROL AT FAIRS 



The following is copied from last year's report. No changes from last year's recom- 

 mendations are necessary: 



Fair officials will need to be sure that manure, garbage, refuse, and soft-drink bot- 

 tles are removed from the grounds every day. This is a must. 



A few days before the fair starts, spray livestock sheds, outdoor privies, empty food 

 tents, and other buildings thay may harbor flies with dimethoate (Cygon), fenthion (Bay- 

 tex) or Ravap. A farm crop sprayer, equipped with a lead of hose and a spray gun, can 

 be used for this purpose. Apply the spray to the ceilings and walls to the point of 

 runoff. Most rotary pumps on these sprayers can be adjusted to operate at 250 to 300 

 pounds of pressure. If the water pressure is good (30 p.s.i. or more), a spray gun 

 that fits on the end of a garden hose will do a good job of applying the insecticide. 



Sprays should also be applied to refuse containers, garbage cans, and the like before 

 and during the fair. A couple of men with compressed-air tank sprayers can do this job. 



Flies are attracted from great distances to the odors of animal waste and foods. These 

 flies are not killed until they land on a treated surface. For a quick knockdown of 

 these incoming flies in animal shelters and other places, use a small electric fogger 

 with oil- or water-base pyrethrum, dichlorvos (DDVP) , or naled (Dibrom) . These fogs 

 can be applied best in the early morning when no people are around. Animals need 

 not be removed, although horses may be frightened by the fog. 



Urge that food stands keep some pyrethrum or dichlorvos in a pressurized spray can for 

 the quick kill of adult flies. These sprays should be used at night after the stands 

 close. The local health department should insure that all stands maintain the re- 

 quired standards of cleanliness. 



HOMEOWNER PROBLEMS 



Again, we copy from last year's bulletin. After all, fleas are fleas. 



Fleas ordinarily annoy only dogs and cats. But left uncontrolled, fleas can become 

 a serious problem in a home or a yard by late summer. They attack people on the legs, 

 often leaving a series of two or three punctures in a row. Persons who take their 

 cat or dog with them on vacation or put them in a boarding kennel may find a multi- 

 tude of hungry fleas waiting when they return home. These adult fleas have developed 

 from the eggs and larvae that were scattered about the house.
