FOREST INSECT INVESTIGATIONS 
F. C. Craighead, Senior Entomologist, in Charge 
Dr. F. C. Craighead spent a week early in May at Melrose Highlands, 
Mass., consulting with A. F. Burgess and C. W. Collins on the rearrange— 
ment of the gipsy moth investigations, necessitated by the transfer of 
research work on this project to the Division of Forest Insects. On the 
same trip a day was spent at Harvard Forest, consulting with H. J. Mac-— 
Aloney on white pine weevil investigations. 
J. A. Beal. and R. A. St. George report the results of several 
sprays used in an attempt to control the locust borer. They find that 
emulsions of orthodichlorobenzene and paradichlorobenzene are very effec— 
tive. Mr. St. George is at present at the Pisgah National Forest, N. C., 
operating with a crew from the Forest Products Laboratory in a cooperative 
study. 
Dr. Ivar Traégardh, Forest Entomologist of Sweden, arrived in 
Washington the last week in May and consulted with this office on the ar-— 
rangement of an itinerary to visit some of the forest—insect field lab- 
oratories and the experiment stations of the Forest Service. He will 
also visit some of the other field laboratories of the Bureau of Entomol— 
ogy. On his itinerary he will visit the southern and extreme western 
laboratories, and return through Minnesota and the Central States. 
J. C. Evenden reports that the Bighole control project is now well 
under way. In the last week in May some 25 camps were established, in-— 
volving about 500 men. During the next four weeks $100,000 will be spent 
Hopk., on an area of about 400 square miles. To cover this area effec— 
tively and economically in such a short time will require everyone con-— 
nected with the project to be constantly on the jump. C. S. Webb, repre- 
senting the Forest Service, is in charge of the project. 
J. M. Miller, in charge of the field laboratory at Palo Alto, 
Calif., reports that field projects are now under way in his district. 
H. L. Person will be located in the Modoc National Forest, Calif., on co- 
operative studies with the California Forest Experiment Station. F. P. 
Keen is planning to conduct again the annual survey of the large Califor-— 
nia-Oregon project in southern Oregon, 
On May 3 William Middleton, of this office, examined considerable 
boxwood in northern Virginia, visiting Strasburg, Winchester, Leesburg, 
and Warrenton. 
On May 15 C. R. Willey, assistant entomologist of the Division of 
Plant Industry, Virginia State Department of Agriculture, visited this 
office to confer with Mr. Middleton on the situation in Virginia regarding 
the box leaf miner.
