TROPICAL AND SUBTROPICAL PLANT INSECT INVESTIGATIONS 
A. C. Baker, in Charge 
On June 4 Dr. A. C. Baker returned to Washington from Mexico, 
after visiting en route the office in Harlingen, Tex., and the field 
laboratory in New Orleans. While in Mexico he completed the organi- 
zation of the work there for research on the Mexican fruit worm, both 
at the central laboratory and at the field insectaries. As a result 
of his negotiations with the Mexican authorities the Mexican Govern- 
ment is providing the Bureau of Entomology with two concrete buildings: 
in Mexico City for the main laboratories, located on the campus of the 
veterinary college formerly there. These buildings have been completely 
equipped for modern entomological research. They contain a constant— 
temperature room, a battery of incubators, Carrier air-conditioning 
units, a complete chemical laboratory, a room for media, a room with 
specially designed lighting for microscopical work, and a shop. 
Dr. Baker, while in Mexico, visited the Governor of Morelos and 
arranged for investigations at Cuernavaca, where an insectary has been 
completed and work has been under way for some time. This is one of the 
field units of the laboratory at Mexico City. The entire program of 
research as outlined is conducted in cooperation with the Oficina para 
Defensa Agricola of the Mexican Department of Agriculture, which is re- 
sponsible for two other field units, one at Vera Cruz and one at Villa 
Hermosa. On the whole, the arrangements are exceedingly satisfactory, 
and the finest spirit of cooperation and good will exists. The projects 
of the Mexican Government are represented by Dr. Adolph Dampf, who some 
time ago was appointed collaborator in this work. Dr. C. I. Bliss, of 
the New Orleans field laboratory, has temporarily directed the part of 
the work belonging to the Bureau of Entomology, pending the appointment 
of a suitable person to have permanent charge. Mr. McPhail is handling 
the insectary at Cuernavaca. 
On June 25 Dr. Baker left Washington for a trip to the Northwest 
and the Pacific Coast, to look after the organization of the work there 
in charge of this Division. In the State of Washington he will visit C. 
F. Doucette, in charge of the field laboratory at Puyallup for the study 
of insect pests of bulbs; and in California he plans to meet Dr. F. R. Cole 
in charge of the field laboratory at Santa Cruz, Dr. E. A. McGregor, in 
charge of the field laboratory at Lindsay, and Dr. L. Stickney, of Palo 
Alto. He plans to stop also at Indio, where investigations of the date 
scale are being carried on. 
Dr. F. R. Cole, in charge of the field laboratory at Santa Cruz, 
Calif., recently visited the bulb-producing areas near Los Angeles, on 
business relating to insect pests of bulbs and of ornamental plants.
