Grasshoppers are now hatching in many areas of the state and are common 

 in fence rows and roadsides. Populations are not high, and as yet control measures 

 are not needed. Also,, hard rains may have killed many of the newly hatched nymphs. 



Chinch hugs so far have not "been abundant enough to cause alarm. However, 

 in eastern Illinois, observe small grains closely, particularly bad spots or thin 

 stands. Chinch bugs are most likely to be abundant in areas that have not had rain 

 for some time. 



If chinch bugs start to migrate from small grain to corn, apply l/2 pound 

 of dieldrin as a border about 1 to 2 rods into the grain field and into the corn 

 fields as far as the bugs are severe. Do not harvest small grain for one week after 

 treatment or use the straw until 30 days after treatment. 



Armyworms have been reported from several areas. They have been most com- 

 mon in luxuriant growths of wheat. If there are six or more per linear foot of 

 drill row, apply l/h pounds of dieldrin or 1 l/2 pounds of toxaphene per acre. Do 

 not harvest the grain for at least one week after treatment. Do not use the straw 

 until 30 days after application. 



Eagworms are hatching in central Illinois. If they are abundant enough 

 to require control, apply as soon as you notice the small bags. For small amounts 

 of spray, use 1 tablespoon of lead arsenate, malathion wettable powder, sevin wet- 

 table powder, or 60$ toxaphene emulsifiable concentrate or 2 teaspoons of malathion 

 emulsifiable concentrate per gallon of water. Do not use malathion on Cannert red 

 juniper. 



Stored-grain insects . With wheat harvest just around the corner, stored- 

 grain insects hidden in empty bins are preparing for the big feast. Prevent damage 

 from these pests by sweeping up and cleaning out all old grain and other debris 

 inside and around the bin. Then spray all inside surfaces to runoff with a 1.5$ 

 premium-grade malathion or 2.5$ methoxychlor. Also treat the wheat, as it is being 

 binned, with a liquid or dust form of premium-grade malathion. These three steps 

 will insure insect- free wheat for a year or more. 



Caution : Before applying insecticides, read the labels carefully and 

 follow all precautions. This will not only insure personal safety, but will also 

 eliminate insecticide residue hazards.

 ticides, write to 280 Natural Resources Building, University of Illinois, Urbana,
