TTHE ACTIVITIES of the Bureau 

 A of Entomology are primarily de- 

 voted to research, although several 

 important regulatory projects in co- 

 operation with the Federal Horticul- 

 tural Board and the State experi- 

 ment stations and State departments 

 of agriculture form part of its 

 scientific program. Although re- 

 search thus constitutes the major 

 function of the bureau, this is di- 

 rected toward the solution of eco- 

 nomic problems, so that the bureau's 

 aim is one of practical service 

 through scientific research. The 

 work includes a study of insects 

 injurious to crops and crop prod- 

 ucts and the development of meth- 

 ods for eradication or control, a 

 study of those affecting the health 

 of livestock and of man, and those 

 infesting human habitations or in- 

 jurious to our industries. It in- 

 cludes also a study of beneficial 

 insects, both those forming the basis 

 of certain industries or on which 

 more limited industrial processes 

 depend and those which may be 

 utilized as insect-controlling agen- 

 cies in the solution of agricultural 

 problems. With the exception of 

 the research on taxonomy, the work 

 of the insect pest survey, and that 

 of a few technical laboratories, all 

 of the activities of the bureau other 

 than those of administration are 

 conducted in the field. Much of the 

 field investigational work is done 

 in cooperation with the State agri- 

 cultural experiment stations.
