DECIBDUOUS-FRUIT INSECT INVESTIGATIONS 
A. L. Quaintance, in Charge 
G. F. Moznette, in charge of the pecan insect laboratory at Al-— 
pany, Ga., spent August 1 to 4 at Spring Hill, Ala., near Mobile, con-. 
ducting control experiments with the black aphid of the pecan, Myzocallis 
fumipennellus Fitch, which has been causing serious damage to pecan trees 
in the vicinity. The feeding of this aphid leads to defoliation. 
G. F. Moznette reports that the two recent tropical disturbances 
which swept through Georgia did considerable damage to the pecan crop. 
The loss per tree will average from 1 to 4 pounds, depending on the age 
of the tree. Under some large trees from 500 to 600 nuts have been gath-— 
ered from the ground. 
John F. Payne, pilot of the Tallulah, La., field laboratory, spent 
August 8 and 9 in airplane dusting of pecan trees at Albany, Ga., in co- 
operation with G. F. Moznette. 
During the week of August 6 to 11 H. S. Adair, in charge of the 
pecan insect field laboratory at Brownwood, Tex,, visited Houston, Tex., 
and collected some pecan material there, finding that damage by the nut— 
case bearer had been unusually heavy. The laboratory at Brownwood re- 
ceived some material from there earlier in the season, and a number of 
hyperparasites were reared. These insects may account for the heavy 
infestation in the vicinity of Houston in the present season. One grower 
estimated his loss at about 90 per cent of a full crop, and similar 
damage was reported by others. On his return trip from Houston to Brown— 
wood, Mr. Adair stopped at the Texas A. & M. College, College Station, 
and conferred with the Experiment Station entomologists and extension 
workers who are especially interested in pecans. 
C. H. Phipps, Associate Entomologist, Dr. H. C. Hildreth, Hor-— 
ticulturist engaged in blueberry investigations, and Robert Chandler, 
Assistant Horticulturist, all of the Maine Experiment Station, Prof. K. 
H. Salman, of the Department of Entomology, Massachusetts Agricultural 
College, Warren Pettigrew, of the Maine State Department of Agriculture, 
and C. W. Collins, of the Gipsy Moth and Brown-tail Moth Investigations, 
Bureau of Entomology, visited the blueberry maggot field laboratory, 
Cherryfield, Me., late in July and early in August. 
On August 14, Fred E. Brooks, in charge of the field laboratory, 
at French Creek, W. Va., visited Washington on business relating to his 
work on nut insects. 
C. T. Blanz, a resident of Washington, D. C., has been given tem-— 
porary appointment to assist in investigations and control of nut weevils 
in the government chestnut orchard at Bell, Md. 
Prof. Bernard Trouvelot, entomologist at the Institut des Recher- 
ches Agronomiques, at Versailles, France, visited the field laboratory at 
Yakima, Wash., on August 27 and 28.
