The annual meeting of the Forest Service Regional Investigative 
Committee for Region 5 was held in San Francisco, March 2 to 4, and was 
attended by J. M. Miller and K. A. Salman. In the review of the research 
program of the Bureau of Entomology the discussion centered largely on 
the regional survey of bark-beetle infestations which will be started by 
the Berkeley laboratory during the coming field season. 
J. A. Beal, of the Portland, Oreg., field laboratory, has com- 
pleted his report on studies of insects developing in logging operations 
in western yellow pine. This study was based upon tractor logging on the 
Weyerhaeuser operation near Klamath Falls. 
A report covering the 1930 season's experimental work on the fir 
engraver beetle (Scolytus ventralis) was completed by G. R. Struble dur- 
ing the past month. The report includes a study of losses in white fir, 
the life history of S. ventralis, and studies on a fungus associated with 
5S. ventralis. Experimental work in the laboratory on high temperatures 
as they affect the larvae of S. ventralis show that their lethal point is 
@pout O° higher than that for the larvae of Dendroctonus brevicomis. 
show a wider range of development than for the larvae of D. brevicomis. 
J. C. Evenden of the Coeur d'Alene, Idaho, field laboratory, and 
F, P. Keen of the field laboratory at Portland, Oreg., attended the annual 
meeting of the Western Forestry and Conservation Association in Spokane, 
Wash., on March 19 to 21, inclusive. Mr. Keen presented a paper at this 
meetang, Outlining the present status of insect conditions within the 
western forests, as well as the investigative program which is under way. 
This paper was well received, and forest-—insect problems were given con- 
Siderable attention at this meeting. 
B. H. Wilford, under temporary appointment with the Bureau, re- 
ported for duty in Coeur d'Alene on March 2. He will have charge 
of the field operations in connection with a study of the spruce budworm 
which is to be conducted within the Cody Canyon, Wyo., during the coming 
season. The purpose of this study is the development of a method of con- 
trol which will be both effective and economical in the protection of 
trees which have high scenic values. 
C. W. Collins, in charge of the gipsy-—moth laboratory, gave a talk 
concerning its activities before the Boston U. S. D. A. Club on March 24, 
In connection with his talk, three motion—picture films of the Department 
of Agriculture were shown. These films have to do with the life histories 
of the gipsy and brown-tail moths, their parasites, and methods of con- 
trol. 
In the Monthly letter for November, 1930, it was stated that a 
small shipment of parasites of the birch leaf-mining sawfly, Phyllotoma 
Nemorata Fall., had been received from P. B. Dowden, of the European 
gipsy moth station at Budapest, Hungary. A second shipment, containing 
an additional hymenopterous parasite, has since been received.: Both lots 
of material were secured in northern Austria,
