PINK BOLL WORM ( Pectinophora gossypiella Saund. ) 
The finding of the first pink bollworms in the 1931 col^t-on crop in 
the Salt River Valley of Arizona, on May 5 and 5, was mentioned in last 
month's News Letter. The two fields involved are located about 10 miles 
southwest of Phoenix and some 15 miles west of the 1930 noncotton zone, 
in the Lave en section. Since then specimens have been fovmd in two 
additional fields. On May 11 one larva was found in a field about 6 
miles east of the 1930 noncotton zone. An exit hole was found in a- 
green boll from this field on May 22, indicating that the first gener- 
ation of the current season had already begun to emerge. Since the 
initial infestation was found, additional specimens have been taken from 
this field and the two fields about 10 miles southwest of Phoenix 
mentioned in the July 1 number of the Survey Bulletin. One specimen 
was taken from a field about 4 miles south of the 1930 noncotton zone 
on May 29, this being in the Goodyear vicinity. 
During May 2,373 samples of bolls were inspected at the San Antonio 
laboratory s this being the greatest amount inspected any month since the 
laboratory has been in operation. These samples represented fields in 
216 counties in the States of Alabama, Arkansas, Florida, Georgia, Louisi- 
ana, Mississippi, Oklahoma, South Carolina, and Texas. Samples had 
already been inspected from North Carolina and Tennessee. A total of 
7,892 samples had been inspected at the close of May, all with negative 
results. 
EUROPEAN CORN BORER ( Pyrausta nubilalis Hbn.) 
The first European corn borer pupa found in 1931, as reported by the 
Arlington Laboratory, was collected in the vicinity of Arlington, Mass., 
on April 16, and the first record of emergence, also in that neighborhood, 
was made on May 22. 
GIPSY MOTH ( Porthetria dispar . L. ) 
In New Jersey the work which is being done cooperatively by the 
Federal and State forces consisted mostly of checking up work around 
previously infested areas. This was practically completed during the 
month and no infestations were found. Many of the Federal men in New 
Jersey were transferred during the last, of May to Massachusetts and 
Connecticut to assist in the spraying work which was being done there 
during June.
