a century, but not until 1914 was it recognized as a pest. During November 

 and December of tliat year numerous complaints were made of damage to corn 

 in cribs, especially in Mississippi. The attack begins in the field and continues 

 after the corn has been stored. When the stored ears are husked they show 

 injury by accumulations of webbing and frass or excrementitious matter. 



" The eggs are deposited in the field where the tips of the corn ears are 

 more or less open, due to the attack of the corn ear worm. After the latter 

 has departed the pink corn worm continues the injury and by its work makes 

 it easy for other insects and water to enter the ears, which eventually are 

 ruined. From the cob or between the rows of grains the worm penetrates the 

 kernels at the tip or point of attachment, works into the embryo or ' germ,' 

 which it destroys, then outward to the crown. 



" Unlike the Angoumois grain moth and the rice weevil, which are usually 

 to be found working in the same fields and frequently in the same ears, this 

 ' worm ' does not confine itself to the kernel, but attacks kernel, husk, and cob 

 alike. 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 plant<5, 



" 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. 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. Nat- 

 urally it can not be foretold when, if ever, such an outbreak will recur. 



"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. The bins or cribs should be kept scrupulously clean, 

 and should be fumigated before new material is stored in them. Cooperation 

 among corn growers of as large a territory as possible where the species occurs 

 should be secured that future losses may be prevented."

 source of considerable injury to coconut palms at Georgetown during 1914, 

 approximately 5 per cent of the palms having succumbed to its attack.
