1908. From the Preface: In preparing the following pages the author has been more and more impressed by the fact that for the control of most of the worst insect pests of our staple crops, the farmer must depend very largely upon general methods of farm practice. This being the case, it is essential that he have a correct knowledge of the pest to be combated; such a knowledge of its life history as will make plain the reason for the effect of any given procedure against it. Contents: Injury Done Staple Crops by Insect Pests; Structure and Development of Insects; General Farm Practice against Injurious Insects; Beneficial Insects; Insects Injurious to Grains and Grasses; Insects Injurious to Wheat; Insects Injurious to Indian Corn; Weevil in Grain; Insects Injurious to Clover; Insects Injurious to Cotton; Insects Injurious to Tobacco; Insects Injurious to the Potato; Insects Injurious to the Sugar-Beet; and Insects Injurious to the Hop-plant.
