FOREST INSECTS 
F. C. Craighead, in Charge 
Dr. Craighead returned about the middle of August from a trip 
of inspection of the western field laboratories. About 10 days were 
spent in Idaho and Montana, and a similar length of time in northeastern 
California. 
L. G. Baumhofer reports that a large number of Campoplex in- 
dividuals have been reared and introduced into more remote regions of 
the Halsey, Nebr., plantations, where the tip moth is abundant. Campo- 
plex is an eastern parasite of the tip moth; it has been successfully 
established in these plantations at Halsey, and is doing very effective 
work. 
R. A. St. George reports from Asheville, N. C., that the southern 
pine beetle has been particularly abundant this year. The dry season 
has apparently been favorable to it, and local outbreaks have occurred 
in many places from Virginia south through the Piedmont region. 
Dr. T. E. Snyder left Washington August 28 for Berkeley, Calif., 
to consult with Dr. S. F. Light, of the Termite Investigations Committee 
of the University of California, and Dr. A. E. Emerson, of the University 
of Chicago. From September 1 to September 14 conferences are to be held 
to discuss the fundamental principles of termite control. Dr. Snyder | 
is expected to return to Washington about September 20.
