Airplane dusting against hemlock looper.-~J. A. Beal, Portland, 
Oreg., attended a meeting of the Gray's Harbor Chamber of Commerce 
called to consider what should be done about the new outbreak of hem— 
lock looper covering some 30,000 acres in that county. Mr. Beal ad- 
vised against airplane dusting on such a large area where the extent 
and location of ege laying was not known and where the infestation was 
no longer localized as on the Pacific County area treated by airplane 
dusting last year. 
CEREAL AND FORAGE INSECTS 
Foreign parasites of the sugarcane borer liberated in Florida.— 
W. B, Haley, of the New Orleans, La., laboratory, spent 10 days at Mi- 
ami, Fla., in May liberating foreign parasites of the Sugarcane borer 
(Diatraea saccharalis Fab.) in the cane growing sections of the Ever— 
glades. These were adults only of the dexiid fly Paratheresia clari- 
palpis Tns. and the braconid wasp Ipobracon rimac Wolcott, shipped by 
airplane directly from Trujillo, Peru, to Miami. Mr. Haley, travelling 
by automobile, brought with him from New Orleans also a consignment of 
the dexiid in a well-ventilated cage. This consignment arrived in ex- 
cellent condition. 

Parasite of gray sugarcane mealy bug introduced.--T. FE. Holloway, 
of the New Orleans laboratory, reports that, through 0. H. Swezy, of 
the Hawaiian Sugar Planters’ Association, four shipments of Pseudococ-— 
cobius terryi Full., a promising parasite of the gray sugarcane mealy 
bug (Pseudococcus boninsis Kuw.), have been received at the New Orleans 
laboratory. These shipments were made by steamer cold room, from Hon-- 
Olulu to San Pedro, Calif., where they were received by A. P. Messen— 
ger, of the California State Department of Agriculture. Mr. Messenger 
transhipped them by airplane to New Orleans, where the parasite is now 
being bred successfully and is being released in Louisiana cane fields. 

Alfalfa weevil discovered in San Joaquin Valley.--R. A. Blanchard, 
Sacramento, Calif., reports that Hypera postica Gyll. "was discovered 
in an alfalfa field 3 miles east of Tracy, Calif., in the northern San 
Joaquin Valley on May 12. Only one adult was taken at that time. A 
survey of the area immediately around Tracy, on May 14, showed only a 
very light infestation. On June 2 a rather heavy infestation with con- 
siderable damage to spots in some fields was observed near Pleasanton 
in the Livermore Valley. Such damage occurred particularly near the 
fence rows. Sweepings in two fields gave an average of 97 larvae ard 
12 adults per 100 sweeps with a 12-inch net, with a range from 10 to 
222 larvae and 2 to 32 adults. Ground and plant examinations showed an 
average of 3.8 adults per plant and 2.4 pupae or larvae in cocoons. 
All stages of larvae were swept in the field."
