Number 124 
GIPSY MOTH AND BROWN-TAIL MOTH INVESTIGATIONS 
A. F. Burgess, Entomologist, in Charge 
A number of the men of this Division attended the summer meeting of the 
northeastern entomologists held at Philadelphia and vicinity July 30 to 
August 1. Much interesting and helpful information was secured from the 
survey of the territory infested with the Japanese beetle and an inspection 
of the experiments under way. An excellent opportunity was given to examine 
many of the field experimental projects on insect pests affecting different 
crops in eastern Pennsylvania and southern New Jersey. 
. A. F. Burgess left field headquarters of the Division at Melrose 
‘Highlands, Mass., on June 14 for a trip to the Pacific coast. En route he 
visited a number of the stations and field projects of the Bureau and con- 
ferred with the entomologists in a number of the States. The experiment sta- 
tion and State entomologist's office was visited at Bozeman, Mont. A part 
of the area at Vancouver, B. C., where the satin moth has become established, 
was examined, and a number of places in the residential sections of Seattle, 
Wash., were inspected, where insecticides have been used to control the 
European earwig. From June 25 to 27 he attended a meeting of the Pacific 
Slope Branch of the American Association of Economic Entomologists, at Stanford 
University, Palo Alto, Calif. This was a very successful and enthusiastic meet- 
ing and many valuable papers were presented. After visiting the entomological 
department of the University of California, at Berkeley, and the Academy of 
Sciences at San Francisco, he proceeded to southern California. One day was 
spent at the Bureau laboratory at Alhambra and in visiting field projects con- 
nected with its work, and another day was occupied in visiting a number of 
county parasite stations, where natural enemies of citrus insects are being 
reared on a wholesale scale for field liberation. The entomological department 
of the Citrus Experiment Station at Riverside was visited and an opportunity 
‘was afforded to see the plant and equipment used in connection with parasite 
investigations. At Salt Lake City a day was spent at the alfalfa weevil 
laboratory of the Bureau, where the work on this insect and the parasite intro- 
duction and investigation work were examined. In company with Messrs. Edmonston 
and Hofer, of the Forest Insect Branch of the Bureau, an inspection trip 
was made to the Kaibab National Forest, where extensive work was being carried 
on to control a severe outbreak of Dendroctonus in the pine forest. Several 
crews of men were engaged in felling and peeling infested trees. In certain 
sections large areas of pine have been killed as the result of the work of this 
insect, and the whole forest, covering many hundreds of square miles, is 
threatened. Mr. Burgess takes this occasion to express his thanks to the ento- 
mologists whom he met on this trip for the many courtesies extended and the 
opportunities that were given him for seeing the important projects in the 
districts visited.
