INTRODUCTION 



oon after the outbreak of World War II the need for improved 

 methods for controlling the insect vectors of various diseases of 

 importance to military personnel engaged in a worldwide conflict 

 was recognized by medical officers in the office of the Surgeon General, 

 U. S. Army, and by civilian consultants on military medical problems. 

 Research to develop such measures was undertaken by the former 

 Bureau of Entomology and Plant Quarantine in 1942 at the request 

 of the War Department. Most of this research has been conducted 

 at Orlando, Fla., but some studies have been made at Beltsville, Md., 

 and Savannah, Ga. 



This research was financed by the Office of Scientific Research and 

 Development on recommendation of the Committee on Medical 

 Research of the National Research Council until the end of the war 

 in 1945. Financial support was then provided by the War Depart- 

 ment and since has been assumed by the Departments of the Army 

 and Navy. These programs have been reviewed and sponsored by the 

 Army Committee for Insect and Rodent Control. 



The following branches of the Department of Defense have assisted 

 in conducting the work and in furnishing personnel, supplies, and 

 equipment: The offices of the Quartermaster General, the Chief of 

 Engineers, and Chief Chemical Officer of the Department of the 

 Army; the U. S. Army Typhus Commission; the Army Air Forces 

 Center, Orlando, Fla. ; Brooke Army Medical Center; and other Army 

 posts. Informal cooperation was also received from the Food and 

 Drug Administration, the National Institutes of Health, the Army 

 Environmental Health Laboratory, the Tennessee Valley Authority, 

 the Rockefeller Foundation, and the Arkansas State Board of Health. 



In the course of this work thousands of new chemicals and chemical 

 formulations have been investigated as insecticides and repellents. 

 Much of the information obtained has been reported in scientific 

 publications dealing with specific subjects. Those materials and 

 methods that have proved to be or offer promise of being of practical 

 value are summarized in this circular. Information available at the 

 end of the war was reported in Miscellaneous Publication No. 606, 

 entitled "DDT and Other Insecticides and Repellents Developed for
