Fifth Report of the United States Entomological Commission on Insects Injurious to Forest and Shade Trees

Abstract

VERY valuable Reports have been presented by the United States Entomological Commission from time to time. Among these may be mentioned that upon “The Rocky Mountain Locust,” prepared by Prof. Riley in 1878, which is a most exhaustive record of the habits of this terrible pest, and of methods of prevention and remedies against its attacks. Later on, an equally valuable and instructive Report was submitted with regard to the cotton worm (Aletia argillacea), very destructive to the cotton plant, whose crop it has reduced in some seasons from 30 to 75 per cent. in the principal cotton-producing States. Both these elaborate works, as might be expected from their authors, Prof. Riley and Dr. Packard, who practically constituted this Entomological Commission, are full of interesting experiments, ingenious contrivances, and subtle devices, to circumvent the insect hordes advancing with the insistance of invading armies.
