diazinon-methoxychlor mixtures, and malathion-methoxychlor mixtures may be used for 

 control. Malathion can be used alone -when the air temperature approaches 60° F. and 

 is predicted to remain there for several hours. Experienced applicators may want to 

 apply azinphosmethyl (Guthion) or methyl parathion. Observe all label precautions. 



Clover leaf weevils are present in red clover fields. Although a few fields with high 

 populations ha\ r e been observed, damage remains slight. No need for chemical control 

 is anticipated. 



CORN INSECTS 



European corn borer survival appears to be a bit lower than normal in the southwestern 

 area of Illinois, but at least as high as usual in western and northwestern sections 

 of the state. 



DAIRY FARMERS: Remember that it is now illegal to use aldrin or heptachlor as soil 

 insecticides on your farm. 



SOYBEAN GROWERS: Do not plant soybeans in a field in 1972 where either aldrin or hept 

 chlor was used for corn soil insects in 1971, plus any other year back to 1966. The 

 beans will contain slight residues. Even though these are so small that no public hea: 

 problem could ever exist, the amounts may be illegal. 



LIVESTOCK INSECTS 



Cattle lice populations in southern Illinois are much lower than in previous years. Tb 

 reason is unknown.

HOMEOWNER INSECTS 



Ants, water bugs, spiders, crickets, and other crawling insects can be prevented from d 

 tering your home by spraying the outside foundation wall with a 1-percent emulsion of 

 chlordane and water. Purchase chlordane as a liquid concentrate and mix a half pint o: 

 45-percent chlordane or 10 tablespoons of 72-percent chlordane in 3 gallons of water. 

 Spray the foundation wall from the ground to the sill, or about a foot, to the point o: 

 runoff. In addition, spray 3 to 6 inches of soil adjacent to the wall, as well as the 

 expansion joints along porches and steps. Do not spray shrubbery or flowers. The oil 

 in the spray may burn the tender foliage. 



For controlling ants already inside the home, use 0.5-percent diazinon or 0.5-percent 

 Baygon in pressurized spray cans. Spray into all cracks, around baseboards, and other 

 areas where the ants are observed. 



Eastern tent caterpillars are defoliating trees, especially wild cherry in Southern 

 Illinois. These dark- colored worms with a white stripe down the back spin webs on the 

 branches and trunk as they move along and feed on the foliage. 



Spraying with carbaryl (Sevin) or malathion will control these worms. Do not treat if 

 the caterpillars are almost full-grown (2 inches long) or are pupating. 



Boxelder bug s have been a pest in many homes this spring. Although these bugs are a 

 nuisance, they do not feed on household furnishings. Last fall these red-and-black 

 bugs migrated from boxelder trees into buildings to hibernate for the winter. To pick
