226 INSECTS AFFECTING WHEAT. 



these is a fungus that develops on the surface of 

 the bug as a dense white covering. This disease is 

 illustrated at Fig. 119 : a number of the dead bugs 

 are shown on a dead wheat stalk at the left, while a 

 single bug, much magnified, covered with the fun- 

 gus, is represented at the right. This fungus belongs 

 to a genus of plants called by botanists Entomoph- 

 thora. 



Remedies. — Professor S. A. Forbes has divided 

 the remedial and preventive measures applicable to 

 the Chinch Bug into three general classes, namely : 

 (1) Agricultural methods ; (2) Barriers against mi- 

 gration ; (3) Direct destruction. Under the first of 

 these heads are included (1) clean farming, especially 

 the cleaning up of refuse that may serve as protec- 

 tion for the bugs during winter, and the destruction 

 of the grass-like weeds upon which they feed ; (2) 

 diversified farming and the culture of crops not 

 affected by the Chinch Bug; (3) the temporary aban- 

 donment, in corn districts, of small grains, especially 

 wheat and barley ; and vice versa, the similar aban- 

 donment of corn in small grain districts; (4) heavy 

 fertilization to enable the crops better to withstand 

 attack; (5) the use of surplus seed, or the mixing of 

 clover or timothy seed with small grains when 

 sowed, to produce a heavy growth in which Chinch 

 Bugs do not like to work ; (6) plowing under the 

 bugs and their eggs whenever this is practicable. 



Under the head of barriers against migration are 

 included: (1) plowing and harrowing at harvest time
