“ Dried tobacco is attacked and frequently ruined, even after having been made up into cigars and cigarettes, by the so-called cigarette beetle (Lasioderma serricorne) , an insect which works not only in tobacco, but in many other dried herbs as well as certain dried foods. It is a cosmopolitan species, and multiplies rapidly throughout the greater part of the year, feeding both as larvae and as adults. ”

“ It is a minute, oval, reddish-brown species occurring upon many solanaceous plants, which makes its appearance in July, attacking the tobacco leaves, which soon present a spotted appearance. Afterwards these spots become holes and the leaf is practically destroyed. In the larval state the insect feeds upon the roots. The small holes eaten by the beetles become the entrance points of bacteria, which start a leaf-disease which may be more injurious to the plant than the actual work of the beetles. ”

“ The adult is a small greenish moth, and the larva is found in the bud of the plant about the time it is ready to top. They transform to pupæ under the surface of the ground. A true bug (Dicyphus minimus) damages the second crop in late tobacco by puncturing the leaves and sucking the cell sap. Infested leaves become yellowish in color, somewhat wilted, and the older ones eventually split in places, becoming ragged. The bug, when immature, lives on the under side of the leaves, but the adults live both above and below. ”
