Miss B. M. Broadbent, who has been in California temporarily assisting Dr. F. R. Cole 
on bulb-fly Studies, left there in the latter part of October to join the staff of the New 
Orleans laboratory. She will have with her all the accumulated records on the cyanide 
treatment of Ornamentals, and will review this entire field with Dr. C. I. Bliss and his 
associates. 
C. F. Doucette, who has been in charge of the bulb—fly work in the Northwest, arrived 
in Washington in the latter part of October for consultation in regard to bulb-—insect prob- 
lems. He was then returning from Europe, where he attended the convention of the American 
Legion. He visited the bulb cultures of Holland and England, and learned much that will be 
of value in handling the bulb situation in this sountry. 
E. A. McGregor, of the Lindsay, Calif., field laboratory, reports that he partici- 
pated in the program of the Annual Citrus School held at Lindsay under the auspices of the 
Agricultural Extension Service of the Uuiversity of California. The subject of Mr. McGregor's 
discussion was "Citrus Thrips Control." The members of the school later visited certain of 
the citrus thrips control plots in the groves. 
“A. J. Ackerman, of the Bentonville, Ark., field laboratory, Deciduous-Fruit Insect 
Investigations, went late in October to the field laboratory in New Orleans, for conference 
on data dealing with the biology of leafhoppers gathered at the Bentonville Laboratory 
during the past several years. He expects to be there for some time. 
FOREST INSECT INVESTIGATIONS 
F. C. Craighead, Senior Entomologist, in Charge 
Dr. Craighead spent the third week of October at Asheville, N. C., with J. A. Beal 
and R. A. St. George in making a final examination of some experimental work of the summer. 
One df the interesting results is the demonstration of the ability of DENDROCTONUS FRONTALIS 
to increase from 1,000 to 1,500 per cent in one generation. William Middleton joined the 
party in the fourth week in October to lend a hand in completing the examination before cold 
weather. 
Dr. T. E. Snyder reports that the Pacific Coast Building Officials Conference, at a 
meeting held at Phoenix, Ariz., October 18 to 21, inclusive, adopted without question the 
regulations proposed by pathologists, foresters, and entomologists for preventing ter- 
mite injury and decay in buildings. Dr. Snyder is continuing his trip of inspection of 
damage by termites to Hawaii, where he will spend about two weeks, returning to Washington 
about December 1.
