INSECTS AFFECTING WHEAT. 



eggs in the crevices between the chaff of the wheat 

 heads. These eggs soon hatch into little footless mag- 

 gots that attack the young germ or kernel, blasting- 

 it. About three weeks later they become full grown : 

 they then leave the heads and enter the ground, 

 where they pupate. There is but one brood each 

 year. Besides wheat, the Midge is said to breed in 

 rye, barley, oats and, possibly, grass. 



Remedies. — Early maturing grains are less liable 

 to be infested by this insect than those ripening 

 later. Consequently farmers in regions where it is 

 present plant such varieties earl}', with general high 

 culture. Many of the insects will be destroyed by 

 the deep plowing of the infested fields. 



INJURING STORED GRAIN. 



The Grain Weevil. 



Calandra granaria. 

 There are several species of beetles infesting gran- 

 aries, the habits and life-histories of which, however, 

 are quite similar. As an 

 example we may take the 

 Imported Grain Weevil, 

 the larva of which is rep- 

 resented at Fig. 124 a. 

 The parent insect being a 

 small, dark-reddish snout- 

 beetle (b), deposits its eggs
