FOREST INSECT INVESTIGATIONS 
F.C, Craighead, Forest Entomologist in Charge 
Dr. F. C, Craighead reported for duty as Forest Entomologist Sept. 14. 
Dr. H. E, Burke revorts considerable aamage to the native forest of 
Monterey pine at Facific Grove, Calif., oy a defoliating sawfly, 5, A. Rohwer 
has determined the sawfly as Itycorsia brunnicans Nort., stating that the species 
has not been reared and that practically nothing is known of its habits. Further 
study by Doctor Burke has yielded the eggs of the species, the habits of the 
young larvae, and the fact that nicotine dust promises to be more effective in 
control than lead arsenate. 
R, A. St. George is in the Southern States investigating the status of the 
southern pine beetle and conducting cooperative experimental studies with vari- 
ous companies to prevent and check injury to crude and finished forest products. 
Dr. A. D, Hopkins, former Forest Entomologist, is now devoting all of 
his time to research in bioclimatics at a permanent field station of the Bureau
