FOREST-INSECT INVESTIGATIONS 
F. C. Craighead, in Charge 
Dr. F. C. Craighead and J. A. Beal, in charge of the field labora— 
tory at Asheville, N. C., spent the first two weeks in March at Starke, 
Fla., working with members of the Southern Forest Experiment Station of 
the Forest Service on the interrelation of the turpentine borer (Bupres— 
tis apricans Hbst.) and turpentining operations. It is believed that 
fairly satisfactory measures have been worked out which will effectively 
prevent practically all of the damage by the borer. Mr. Beal remained 
at Starke until the latter part of March to complete observations on the 
feeding habits and oviposition of this insect. 
Dr. T. E. Snyder returned trom Panama on March 26, after inspect— 
ing the experiments with wood preservatives being conducted in the Canal 
Zone. Excellent results are being obtained with brief treatment and 
the tests have been greatly enlarged. On March 28 a conference was held 
under the auspices of the National Committee on Wood Utilization, in the 
Department of Commerce, Washington, D. C., to present preliminary results 
on the uses of treated woods in.the tropics and the latest information 
on the work being done in termite-—proofing buildings. 
From April 1 to June 15 Dr. T. E, Snyder will be on leave without 
pay to give a course in biological entomology at the University of Chi- 
cago, and expects to return to Washington about the middle of June. 
The annual meeting of the District Investigative Committee, District 
5, Forest service, on February 28 and March 1 at San Francisco, was at- 
tended by J. M. Miller, F. P. Keen, and H. L. Person, all of the fiela 
laboratory at Palo Alto, Calif. The program of cooperative projects in-— 
volving forest-insect investigations within the district was reviewed at 
this meeting. 
J. E. Patterson, of the field laboratory at Palo Alto, has @beer 
working up the section on forest entomology in the Naturalists’ Infor- 
mation Manual for Crater National Park. W. D. Edmonston has completed 
drawings for illustrating the manual, which will be issued in mimeo— 
graphed form, This manual is being prepared in collaboration with An- 
sel Hail, Chief Naturalist for the National Park Service, 
The research Council of the California Forest Experiment Station 
met in San Francisco on February 4, Dr. Ray Lyman Wilbur, President of 
Stanford University, presiding. The meeting was attended by Messrs. 
Miller and Person of the field laboratory at Palo Alto. Mr. Person 
read a paper on the experimental work in forest entomology which is be— 
ing carried on in cooperation with the Experiment Station. 
On February 22 J. M. Miller visited the nursery of the Eddy Tree— 
Breeding Station at Placerville, Calif. This station is working on the 
selection and hybridization of conifers, with the object of developing 
better strains of timber-—producing trees. A pine-shoot moth has been 
causing considerable damage in the nursery and transplant beds.
