adult specimens of A. ludens were taken in three' groves in Willacy County in 
January 1934, the first ever taken in this county. Coring the year specimens 
of A. ludens . A. serpentina Wied. , Anastrerha fraterculus auct., A. -oallens 
Coo,, A. striata Schin., Anastrepha spp. (undetermined), the papaya fruit fly 
( Toxotrypana curvi Cauda Gerst.), and an unnamed ; species belonging in the sub- 
genus Pseudodacus . were taken in traps operated in the lower Rio Grande Valley 
of Texas. With the exception of A, striata , of which a single adult was 
trap-oed near Mission, these species have been taken throughout the citrus 
area; of the lower Mo Grande Valley, and with the possible exception of A.. 
fraterculus auct.', none of these species are known to exist elsewhere in the 
continental United States. (P. A. Koidale, Bureau of Entomology and Plant 
Quarantine, U. S. D. A.) 
CITRUS 3LACKELY 
In a memorandum dated October 15, 1934, Dr. Wilmon Newell, >of the State 
Plant Board of Florida, makes the following statement: "On August 10 of this 
year inspectors operating at Key West discovered an infestation of the spiny 
citrus whitefly or blackfly ( Aleurocanthus wo^lumi Ashby). A survey indicated 
that from a central point of heavy infestation the insect could be found in 
diminishing quantities for a distance in all directions of -from one-fourth to 
one-third mile. ' On August 11, at a conference of United States Department of 
Agriculture and State Board representatives, an intensive spraying cam-oaign 
was determined upon. Such a carroaign, using an oil spray built after a 
formula recommended by the Bureau of Entomology and Plant Quarantine and 
applied with power equipment su.rolied by that Bureau, was immediately insti- 
tuted. The campaign was supported by city and county governmental organiza- 
tions and contemplated as an initial effort three thorough applications of 
the oil spray at 30-day intervals. At the same time, removal of host material 
from Key West was prohibited. Intensive inspection by a large force of 
trained operatives has- failed to disclose any infestation other than that at 
Key West. The oil -spray appears to be effective in killing the fly in its 
various stages," 
BOLL WEEVIL 
Low temperatures during the latter part of January and February along 
the Atlantic coast caused heavy mortality of the boll weevil and very few 
weevils survived in Virginia and the Carolinas. At the Florence, S. C, 
laboratory the survival in the hibernation cages was the lowest ever recorded. 
Although the survival was somewhat lower than normal in Georgia and Alabama, 
it was higher in those States than in the Carolinas. In Mississippi the 
survival was fairly high but shotted, and in Louisiana, it was high. At the 
Tallulah, La., laboratory, the survival in the hibernation cages has been 
exceeded in only 1 previous year, 1C32, following the warmest winter since 
the laboratory was established. Survival was also high in Oklahoma and Texas. 
During the growing season dry weather in June and July held down infestations 
in the eastern part of the Cotton Belt, and the drought in Oklahoma and Texas 
not only held down the population, but was so severe as to seriously affect 
cotton production. After rains began in August the weevil population devel- 
oped rapidly in those States and caused considerable damage to the late crop
