Written out of a large scientific knowledge, but in a popular style, this book 

 discusses concisely and yet fully the characteristics, life histories, and means of 

 control of our common injurious insects. 



The illustrations are from photographs throughout. The idea of the author 

 has been to picture graphically the injurious stages and the work of the various 

 pests, so that they may easily be recognized, independently from the text. More 

 than 135 of the illustrations are photomicrographs. 



All of the common injurious forms are described, including the pests of or- 

 chard, garden, field crops, domestic animals, and the household. 



The arrangement of species is original and unique. In each division the 

 pests are grouped according to the place where found at work and the charac- 

 teristics. Prompt identification is thus made easy. 



Other valuable features of the volume are : 



Complete directions for the preparation and use of insecticides. Spray for- 

 mulae, repellents, and fumiganls described in detail. 



Descriptions and photographs of spray machinery and accessories. 



An illustrated discussion of the structure of insects. How they live : their 

 habits, senses, and manner of growth. 



Insects as carriers of disease. The typhoid fly, trie malarial mosquitoes, and 

 others. 



The classification of insects, including illustrated descriptions of the various 

 important groups into which insects are divided. 



An account of the means by which insects are dispersed. 



The natural enemies of insects. How they are held in check by parasites, 

 by fungous and bacterial diseases, and by birds and other larger animals. 



How farm practice assists in insect control, showing the influence of plow- 

 ing, cultivating, destruction of weeds, and the like. 



A complete bibliography, giving an authoritative reference for each species 

 treated in the book.
