r trichlorfon (Dylox) at 1 pound of actual chemical per acre. It is best to use at least 

 D gallons of water per acre and to cover the spray band by throwing soil at the base of 

 ~ie plants with a cultivator . 



pm flea beetles could soon be a problem in newly emerging corn. These small, black, 

 hiny beetles that jump when disturbed eat white scratch marks on the leaves. Damaged 

 lants first turn whitish or silvery, and sometimes are killed. If damage is severe 

 ad plants are being killed, apply 3/4 pound of carbaryl (Sevin) or 1-1/2 pounds of toxa- 

 dene per acre as a band spray over the row. 



VALL-GRAIN INSECTS 



rue armyworms are present in thick, rank stands of wheat and barley in the southern and 

 outhwestern sections of the state. As yet, they are still small and are not numerous 

 nough to cause problems. However, the situation will bear watching as more eggs are 

 aid and hatch. Cool, wet weather favors this pest. 



o not confuse the striped armyworms with the transparent ye How -to -green sawflies . An 

 rmyworm has five pairs of abdominal prolegs ; sawflies, six or more pairs. In many wheat 



ields , we saw more sawflies than armyworms . Sawflies do not damage wheat plants enough 

 o require control . 



OMEOWNER INSECT PROBLEMS 



all cankerworms have hatched, and the larvae are beginning to feed on leaves of shade 

 rees . This is particularly true in northeastern Illinois. These cankerworms like apple 

 r elm, but will also feed on other fruit and shade trees. Sometimes these brown, to 

 ark-green, to black measuring worms completely strip trees of their new spring foliage, 

 hile other trees may be only partly defoliated. When full grown, the worms drop to the 

 round by means of a silken thread that appears like a streamer in the wind. By this 

 ime, it is too late for control. For best results, spray the foliage while the worms 

 re still small and before the damage becomes severe. Use either 2 pounds of 50-percent 

 arbaryl (Sevin) wettable powder or 1 quart of 50- to 57 -percent malathion liquid con- 

 entrate per 100 gallons of water. 



awthorn leaf miner maggots will soon disfigure the leaves of Hawthorn trees. They damage 

 he leaves by eating the tissues between the upper and lower surfaces . Small brownish 

 atches develop along the edge of infested leaves. If your Hawthorn has been bothered by 

 eaf miners, spray the leaves now with malathion (2 teaspoons of 50- to 57-percent liquid 

 oncentrate per gallon of water) or diazinon (2 teaspoons of 25-percent liquid concentrate 

 er gallon of water) . 



lothes moths and carpet beetles are getting ready for a summer's feast on improperly 

 tored woolens. A small hole chewed in a piece of clothing may destroy its entire value, 

 o keep woolens safe from damage by these insects, follow these suggestions. 



. Dry-clean or wash woolens and place them in clean, plastic storage bags or other insect- 

 tight containers . 



. Woolens that are not dry-cleaned or washed should be hung in bright sunlight for a full 

 day and brushed thoroughly before storing. Pay particular attention to pocket interiors, 

 cuffs, and folds when brushing.
