Department of Entomology
In the following pages the life history of several of our most injurious insects is explained, and the best remedies at present known are mentioned. It is hoped that by the aid of the illustrations all the species treated of can be readily recognized. A careful perusal of the article on insecticides ought to suggest practical ways of treating many insects which are not specifically mentioned in the Bulletin. In nearly all cases, our suggestions as to remedies are based on our own experiments and observations.
