VISITS FROM FOREIGN INVESTIGATORS 
In Decerber three entomologists from foreign countries have been 
studying in the Buresu its methods of organization and research, and 
certain problems corresponding to problems existing in their own countries, 
These are Dr. Stepan Soudek, Assistant. Professor of Zoology in the Univer— 
sity of Brno, Czechoslovakia, Dr. V. V. Nikolsky, of the Moscow Tropical 
Institute, and Prof. Kota Monzen, of the Imperial College of Agriculture 
and Forestry at Morioka, Japan. ~ 
Mrs. 0, A. Merritt Hawkes, of Birmingham, England, also spent some 
days in the Bureau, seeking for information concerning Coccinellidae 
and the Ailanthus silkwori, which she is studying in connection with certain 
vroblems of heredity, 

FOREST INSECT INVESTIGATIONS 
Ff. C. Craighead, Entomologist, in Charge 
In the latter part of November Dr. Craighead and Mr. St. George 
spent four days at Asheville, N. C., examining several sample plots and 
cages Which were established last summer. It was found that the southern 
pine beetle had completed five generations in this vicinity between April 
15 and October 15. Several local outbreaks which developed in the latter 
part of the summer have now completely died out; probably because of the 
resuuption of normal precipitation in the latter part of September and in 
October, Although an enormous maumber of beetles emerged during this 
period, no new trees were attacked.except three on an experimental plot, 
from which rain had been excluded by canvas covering. . what happens to the 
enormous number of emerging beetles under these circumstances, and where 
hey are breeding during periods between epidemics, are still mysteries. 
H. J. liacAloney reported at Washington the latter part of November, 
and will spend several weeks here studying past records of the white-pine 
weevil and its parasites. He reports considerable progress on this project, 
which is being financed by private owners of timberland. 
Fieid activities are quiet at the western stations. The men have 
returned to their winter quarters to work up reports on various projects. 
vr, Keen reports that last spring's control operations in the region about 
seagrie Falls have given r enarkably good results, although carried out in 
he face of a rising infestasioz. Plans for a large control project in 
oe San Bernardino Mountains recreational area are being developed by 
private owners and the State Ferester of California, in cooperation with 
she Palo Alto station. Because of phenomenal development of summer homes 
in this region, the barkbeetle losses in yellow and Jeffrey pine are 
regarded as inost serious. The plen proposed contemplates the complete 
eradication of the western pine beetle from this area, which is completely 
isolated from other timber belts,
