But great care is of course necessaiy in such use of poisons. It is not often that an insect attacks three crops which are so different in every way as cotton, corn, and tomatoes. This is the case, however, with the noctuid moth, known by the various names of Bollworm, Corn Worm, and To-, mato Fruit Worm. The cater- pillars have a general resemblance to some of the commoner cut- worms, although they vary greatly in color and markings.

This is the case, however, with the noctuid moth, known by the various names of Bollworm, Corn Worm, and To-, mato Fruit Worm. The cater- pillars have a general resemblance to some of the commoner cut- worms, although they vary greatly in color and markings. In the Southern states, these caterpillars feed to a destructive extent upon the bolls of cotton, on account of which they are called Bollworms. In regions farther nortli, these caterpillars feed inside the husks of green corn, upon the tassels and immature kernels, on account of which they are commonly called Corn Worms or Tassel Worms. In some regions where tomatoes are largely grown, these caterpillars feed upon the green fruit, often boring into it in a very destructive manner; consequently, they have re- ceived the name Tomato Fruit Worm. In the .South, how- ever, the insect does not confine its attention to cotton, for it often feeds also upon green corn even in cotton-growing regions. As a Corn Worm, the life history of this insect may be summarized in these words: The adult yellowish or yel- lowish-green moths appear in the cornfield early in the summer and deposit their eggs upon the leaves or stalks of the growing plants. Four or five days later these eggs. COITON BOLLWORM.
