Excerpt from Insects and Insecticides: A Practical Manual Concerning Noxious Insects and the Methods of Preventing Their Injuries This volume has been prepared for the purpose of furnishing the farmer, the fruit grower, the floriculturist, and the housekeeper with a concise account of the more important injurious insects with which they have to contend, . together with a summary of the latest knowledge concerning the best methods of preventing or counteracting the injuries of these pests. In its preparation free use has been made of the information scattered through the literature of economic entomology; and, as a rule, it has been found impracticable to give to each author credit for first working out the life histories of the various species. In one way or another the contributions of nearly every American economic entomologist have been drawn upon. The illustrations of this volume have also been gleaned from various sources. I am under obligations to the authorities of the Department of Agriculture and various experiment stations, particularly those of Illinois, Cornell University, Colorado, Kentucky, Nebraska, New Jersey and Ohio, - for the privilege of getting duplicate electrotypes.
