THE PINK CORN-WORM. 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, 1t 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.
