Injurious Insects: How to Recognize and Control Them

By W. C. O'KANE

Entomologist of the New Hampshire Agricultural Experiment Station, and Professor of Economic Entomology in New Hampshire College

Illustrated. Cloth, 12mo. $2.00 net.

Complete information on the characteristics, life histories and means of control of the more common injurious insects, including those infesting field crops, vegetables, fruits, the principal pests of domestic animals, stored products and the household, is contained in this book. A distinctive feature of the work is the illustrations with which the text throughout is accompanied. These have been made especially for Dr. O'Kane. With each insect treated he shows in an original photograph the characteristic injurious stage or the typical work of the insect where that is characteristic. By this means the author hopes that the layman will be able to recognize an insect that threatens by the picture aside from any description in the text.
