Losses to cotton, what to look for and where to find it, being one of a series of articles in relation to crops, their common diseases and insect pests to which they are subject . THE SMALLER MEADOW GRASSHOPPER the list of cotton insects contains the names of fourteengrasshoppers which are found upon the plants. The dam-age which the grasshopper causes to the foliage of cotton issimilar to that of the bag woVm and the hickory horn devil. The Cotton Stalk-Borer Puncturing of the terminal portion of the stalk byl^lant bulk occasionally occurs, but is com])aratively is but one borer of the stalks of cotton, and that isthe long-horned beetle known as the cotton stalk-borer. Itis occasionally mistaken for a direct enemy of the plant, 16 but investigation has shown that it lays its eggs upon, andits larva bore into, only such stalks as have been damagedby some other cause, such as rust. It follows injury to theplant, therefore, rather than causes it. There is only one brood of these insects a year, andthey commonly reach maturity in the middle of THE COTTON STALK BORER (a) larva from above; (6) larva from side; (c) tunneled cotton stalk, showing exithole; (f/) adult beetle. All enlarged except c. They frequently pui)ate in the stalk, especially in the caseof large, hollow stalks, but sometimes burrow a short dis-tance into the ground for pupation. The adult is a moth ofa wood-brown color sprinkled with yellowish dots. It isone of the night flyers. The eggs are laid in the earlysi)ring on the stalks attacked. This insect frequently be-<omes abundant enough to do serious damage to plants. White Grubs The young of the May beetles or June bugs are capableof devastating and frequently destroying large portions offarm crops by eating the roots. The crops commonly dam-aged include two of our most important staples, namely,corn and potatoes, but the beetles also attack cotton andare often extremely destructive. These insects require three years to complete
