Elementary Principles of Agriculture 



tecting tomatoes from this insect. Corn designed for 

 " trapping" boll-worms should be planted later than the 

 regular crop. Much better results will be secured if the 

 corn is planted late. (Fig. 103.) 



235. Chinch Bugs infest corn, wheat, oats, and other 



grass plants. They 

 occur widely dis- 

 tributed and do 

 more damage to 

 field crops than any 

 other insect. They 

 are small, dark col- 

 ored sucking bugs 

 (see plate), which 

 infest growing grain 

 throughout the 

 warm season. They 

 are usually present 

 in all grain fields 

 during spring and 

 summer months, 

 and do consider- 

 able damage that is 

 often not noticed. 



While the chinch 

 bugs have wings^ 

 they are inclined to travel by crawling. When a small 

 grain crop is harvested they migrate to near-by corn 

 fields. To protect the corn, the land should be disked 

 at once to destroy the bugs and grass that would feed 

 them. As they migrate to the corn they can be caught 

 in deep dusty furrows and destroyed by dragging a log 

 thru the furrow in the afternoons. They do not migrate

 quarters in this way if present in threatening 

 numbers. Courtesy Prof. T. J. Headlee.
