FOREST INSECT INVESTIGATIONS 
F. C. Craighead, in Charge 
Dr. F. C. Craighead spent three days in Denver, Colo., in the 
Meever part of April, conferring with J. M. Miller and J. C0. Evenden. 
Plans were arranged for the conduct of investicative work for the com- 
ing summer and for the carrying on of certain projects in cooperation 
With the Forest Service. As a result of the increase in ane 
‘for the Division of Forest Insects for the coming fiscal ye a new 
field laboratory will be established at Portiand, Oreg., a Feuen 
Keen in charge. 
At the present time considerable interest is manifested in the 
widespread destruction being wrought by termites to the foundations 
and interiors of buildings in all parts of the country, especially in 
the Central and Southern States. A recent survey of the buildings in 
Memphis, Tenn., by city officials, indicates that from 60 to 70 per 
cent of them are infested by termites. Similar reports are being re- 
ceived from New Orleans, La., and other cities in the Southern States. 
Officials in the various cities are cooperating with the Bureau 
of Entomology in effecting the control of termites in buildings. In 
most instances the entrance of the subterranean type of termites into 
foundations is due to improper methods of construction. To rectify this 
Situation the bureau is recommending brief suggestions for inclusion in 
mandatory city building codes. 
Contributions from the Gipsy-—Moth Laboratory 
Recent visitors to the Gipsy-Moth Laboratory have been William 
H. Thorpe, Demonstrator in Entomology, Zoological Laboratory, Cambridge, 
England, April 2, and H. B. Peirson, Forest Entomologist of Maine, R. L. 
Taylor, graduate student, Bussey Institution, Forest Hills, Mass., and 
W. A. Baker, Bureau of Entomology, European Corn Borer Laboratory, Mon- 
roe, Mich., April 8. 
roximately 30,000 cocoons of the oriental moth, 
J cens valk. reached the Gipsy Moth Laboratory on April 
9. These were co lec nae in Japan by T. R. Gardner, of the Japanese 
Beetle Laboratory, Yokohama, through the cooperation of Dr. A. L. Quain-— 
tance and Mr. L. B. Smith. The oriental moth is well established in 
Boston, Mass., and vicinity, having been first observed there in 1906. 
Rather large collections of larvae and pupae made in recent years have 
indicated that parasism there is negligible; and the shipment of cocoons 
from Japan was made as an attempt to establish where needed in this 
country parasites that attack it in the Orient, especially a tachinid, 
Chaetexorista javana B. & B.
