REPORT ON THE GIPSY MOTH WORK IN NEW 



ENGLAND. 1 



By A. F. Burgess, 

 In Charge of Gipsy Moth and Broivn-Tail Moth Work. 



INTRODUCTION. 



On March 1, 1913, the gipsy-rnoth work conducted by the Bureau 

 of Entomology, U. S. Department of Agriculture, was reorgan- 

 ized, and the writer was placed in charge under the direction of the 

 chief of the bureau. 



The object of this Federal work is to use every measure possible 

 to prevent the spread of the gipsy moth and the brown-tail moth 2 

 to uninfested parts of the United States. 



The main office, which is maintained at 43 Tremont Street, Bos- 

 ton, Mass., furnishes quarters for the men in charge of the main 

 projects and the necessary clerical force. The Gipsy Moth Labora- 

 tory, which serves as headquarters for the experimental work, is 

 located at Melrose Highlands, Mass., although one branch of this 

 work is conducted at the Bussey Institution at Forest Hills, Mass. 

 During the past two years a summer laboratory has been main- 

 tained for special experiments at Worcester, Mass. A storehouse is 

 located at Melrose Highlands, Mass., where the necessary tools and 

 equipment are stored and repaired. 



The work is divided into two distinct lines: (1) Field work ; con- 

 sisting of scouting, and applying hand methods for controlling these 

 insects, as well as a thorough inspection of the plant products shipped 

 from the infested area, and (2) experimental work, which includes 

 the introduction of parasites and natural enemies, together with care- 

 ful studies of the food plants and other factors, in order to devise 

 more efficient and effective methods of control, as well as an investi- 

 gation of the relation of silviculture to the gipsy-moth problem. A
