which they change to a pupa. In about two weeks they 

 come forth as adult moths. There are four or five broods 

 during the summer. The first broods attack the corn, as a 

 rule, the latter broods attacking the cotton bolls, the corn at 

 this season of the year being too hard for them to eat. 



The cotton or boll worm winters in the pupa stage. 



Remedies. — Owing to the peculiar habits of the corn 

 worm, no successful means has yet been devised to control 

 them on a large scale against attacking corn. The only 

 remedy is hand picking. The ends of the ears can be 

 opened and the worms picked out and destroyed. Their pres- 

 ence can usually be told by a premature ripening of the silk. 

 Trapping the moths as suggested under the cotton plant can 

 be used to a good advantage. 



I wish to acknowledge the kindness of Dr. C. V. Riley, 

 and also of the U. S. Department of Agriculture through 

 Dr. Riley, for the cuts of the insects used to illustrate this 

 Bulletin. 



It is hoped that whenever a fungus or other disease, or an 

 insect attacks a plant in sufficient quantities to attract atten- 

 tion, that the person will send a note and a sample or speci- 

 men of the same to J. M. Stedman, Biologist, A. & M. Col-
