THE PINK COEN-WOEM. 19 



the same ears, this "worm" does not confine itself to the kernel, but 

 attacks kernel, husk, and cob alike. 



6. Also, unlike most other grain pests, it appears to be confined 

 among cereals to corn and sorghum, although it attacks, but does 

 not seriously injure, cotton bolls which are more or less open, and 

 some other plants. 



7. While thus far it has proved most injurious in Mississippi, it 

 ranges from South Carolina westward to central Texas, southward 

 to tropical Texas, and northward to Arkansas and Tennessee. 



8. During the years 1914-15 the pink corn-worm was reported to 

 have occasioned very considerable injury, and much alarm was felt 

 because of its abundance in the regions mentioned. Previously, 

 although known to attack corn, it has never been considered a serious 

 enemy of grain. 



9. Naturally it can not be foretold when, if ever, such an outbreak 

 will recur. 



10. As a preventive of injury, corn should be left in the field no 

 longer than is absolutely necessary for drying it; the husks should 

 then be removed as soon as possible, the poorest of the infested ears 

 destroyed promptly or fed to swine or poultry, and the best ears 

 fumigated with carbon bisulphid according to the directions given 

 on previous pages. 



11. The bins or cribs should be kept scrupulously clean, and should 

 be fumigated before new material is stored in them. 



12. Cooperation among corn growers of as large a territory as 

 possible where the species occurs should be secured, that future losses 

 may be prevented.
