CORN 81 



Many bugs may be destroyed by burning such rubbish and 

 grass. The bugs that live through the winter come out in 

 the spring and spread over the country on the wing, settling 

 in fields of wheat, early oats, or other grasses, and in these 

 lay their eggs for the first generation of the year. The young 

 hatching from these eggs injure the crop in which they find 

 themselves. Later, at wheat harvest time, being only partly 

 grown, they move out of infested wheat fields on foot into 

 other fields of grain, especially of corn, where, if the season 

 favors them, a second generation will be bred to the enor- 

 mous injury of the infested crops. 



The successful combating of chinch bugs is a community 

 affair. Every farmer who has chinch bugs on his place should 

 clean up and burn up all trash which would harbor the bug 

 during the winter. In the summer the farmers of the com- 

 munity should all co-operate in throwing crude oil lines about 

 their wheat fields to catch the bugs as they migrate from 

 the wheat to the corn. 



The corn ear-worm. The corn ear-worm injures the ears 

 of corn and is a serious pest, especially to sugar corn. In the 

 South this same insect is known as the cotton boll-worm, from 

 its habit of boring into the boll of the cotton. 



In our latitude the first broods of the moths appear in 

 May and deposit their eggs on corn or other food plants. 

 The second or third broods lay their eggs in the silks or 

 tassels of the corn. The young worms hatch in three or four 

 days, and begin feeding upon the silks of the corn. In a 

 few days they get into the tips of the young ears. Each 

 worm may feed upon several ears, and, when full grown, the
