BOLL WEEVIL -•■ : ■ 
"Owing to hot and dry weather extending throughout practically 
the entire growing season in all States west of Georgia, the population 
of the boll weevil ( Anthon omus grand! s- Boh.) was held "below the point 
of serious damage to the 1930 cotton crop except in so.ne snail local 
areas and in about twelve counties in extreme southern Texas, including 
the Hip Grande Valley, where injury was more than usual. In Georgia the 
infestation was. general and caused more or less' damage except in the 
northwest district. In North Carolina weevils were fairly abundant, 
necessitating the use of control measures in aost districts but were not 
so numerous as in 1929 owing to the dry, hot weather. In South Carolina 
infestation in the northern district was checked by hot, dry weather, 
but was sufficiently serious to warrant the use of control measures to a 
greater extent than in the season of 1929, while in the Coastal Plain 
district a high degree of infestation developed early and continued to 
increase as the season progressed, requiring the use of control measures 
in most counties in that area." 1

"In the summary for 1929 as published in Volume 9, Number 10, of 
the Insect Fest Survey Bulletin, the discovery of larvae of the pink boll 
worm ( Pectino-hora vossyriella Saund. ) in the Salt River Valley. near Mesa, 
Ariz., was reported. The intensive inspection which followed this dis- 
covery disclosed infestation in a considerable number of fields, in this * 
general vicinity. Following the delimitation of the infested area, two 
non-cotton zones were established. These zones included some 40,000 
acres of cotton. One of these zones at its greatest length and greatest 
width is 16 miles and includes the tov.ns of Mesa, Chandler, and Gilbert. 
The other zone is 5 miles square and is located northwest of the village 
of Sacaton* No cotton was produced in these areas during the summer of 
1930. ..Beginning with the crop of this year a new method has 'oeen em- 
ployed in the scouting and inspection work done on account of the pink 
boll worm. A machine has been devised, which serves to very greatly 
reduce the volume of gin trash from the first cleaner and has made it 
possible to examine a considerable portion of the first cleaner trash 
from .gins throughout the area regulated on account of this insect. Gin 
trash machines have also been operated, in a few localities outside of 
the regulated area. The inspections have failed to disclose the presence 
of the pink boll worm at any point outside of the regulated area. Like- 
wise, the intensive inspections have failed to reveal the presence of the 
pink boll worm in certain counties of the Western Extension, (western end 
of cotton belt),, where worms were found during 1927. Failure to find 
infestation in those parts of the regulated area included in Martin, 
Glasscock, Dawson, Howard, and Borden Counties, and in a small part of 
the northeastern portion of Midland County, has led to the amendment of 
the quarantine which removed these areas from the restrictions. The
