in 153^» ?he growers in most pieces also received the "benefit of sufficient 
hot, dry weather during the summer to hold down the weevil population and 
r.Ilo'7 the production of satisfactory crops of cotton. In the northern third 
of the Cotton Belt the weevils ,r ere greatly reduced by the low temperatures 
of the winter of 193^-35 ~- n d were again checked by the hot, dry weather of 
the sunnier. During the spring and early summer conditions were favorable for 
the weevils over a large portion of the central third of the Cotton Belt, 
from the Atlantic coast westward into Texas. Many growers in this area, es- 
pecially in the Delta, sections of Arkpnsas, Louisiana, and Mississippi, made 
preparations for a hard fight against the weevil and some of them "began dust- 
ing in June, "but hot, dry weather in July and August satisfactorily checked 
the weevils in man;'- fields. It was, however, in this central "belt that most 
of the poisoning for' "boll weevil control was done- and most of the serious 
damage occurred. Late in the fall, as the "eevils entered hibernation, they 
were reported to "be more abundant than usual in the vicinity of Florence, 
S. C. , and College Station and Port Lavaca, Tex., while the opposite condition 
was reported from Mississippi, Louisiana, and Oklahoma. The defoliation of 
the cotton plants "by the leaf worms over such a wide range has undoubtedly 
greatly reduced the number of weevils entering hibernation this fall. (P. '"•'.

THUEBEPIA tfEEVIL 
Tae Thurberia -'eevil was first discovered in the United S*ates in 
the latter part of 1912 in mountains near Tucson, Pima. County, A r iz. This 
insect was found on the Thurberia plant, which is related to cotton. At that 
time there were no commercial plantings of cotton in that section, but by 
191S such plantings were begun, and later they were extended along the Santa 
Cruz Valley, in Santa Cruz and lima Counties, and in certain sections of 
Cochise County. Hie weevil was first found in cultivated cotton in 1920, and 
has been found in nearly every crop since then. A few weevils were also found 
in the southern part of Pinal County in 1931 > hut none has been found there 
since. For the past severaiyears practically all of the cotton acreage in- 
volved has been in Pima County. This year, by means of gin-trash inspection, 
15 weevils have been found. The eradication of Thurberia plants, many of 
which are infested, is now being undertaken in the mountain ranges near 
fields of cultivated cotton. (P. P. McDonald, Bureau of Entomology and Plant 
Quarantine, U. S. D. A.) 
PINK BOLLWOEM 
Gin-trash inspection of the 1935 cotton crop is just about completed, 
and no specimens he.ve been found in any new areas this year. No specimens 
were found in the regulated areas in Florida and Georgia, nor in the Plains 
counties of Texas, known as the "'J e stern Extensiono" A very light infesta- 
tion continues to be present in El Paso, Pecos, and Ward Counties, Tex. 1 in 
Dona Ana, Chaves, and Eddy Counties, IT. Mex,, and in Graham County, Ariz. 
A small amount of cotton is grown in Greenlee County, Ariz., but ginned in 
Graham County, and it is uossible that some of the specimens found in Graham 
County originated in Greenlee County. I n the above areas under regulation 
the infestation is very light, and no commercial iama e is being done. In 
Brewster, Preeidio, and part of Hudspeth County, Tex., a considerable number 
of worms is -orer_nt but, because of specia.1 control measures which have been
