20 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1934 
in Ohio, Indiana, Michigan, and Long Island were temporarily reassigned to 
supervise some of the trapping activities in nonregulated Japanese beetle ter- 
ritory. This work was in exchange for an equal amount of time devoted to 
corn borer inspection work by the regular Japanese beetle personnel in Connecti- 
cut, New Jersey, and Pennsylvania. 
Sweet corn harvested in Rhode Island in July 1933 had from 35 to 75 percent 
of the ears infested with corn borers, according to the Rhode Island Department 
of Agriculture. Corn borer infestation was general throughout the State in 
1933, although it was more serious where corn was grown in large quantities. 
The wide-spread infestation was attributed to unusually wet weather in the 
early spring, which prevented a postponed clean-up of the cornfields and also 
favored the development of the corn borer larvae. Inspection by State 
employees of Rhode Island fields where corn was grown in 1933 was begun 
early in April 1934. Owing to the wet condition of the fields in some parts of 
the State, the clean-up date was extended from April 20 to May 15. 
In Connecticut, the first-generation borers caused considerable damage in 
early sweet corn, some fields being a total loss. Surveys to ascertain the extent 
of the 1933 commercial damage done by the corn borer and the approximate 
borer population in Connecticut were made under the direction of the Connecti- 
cut Agricultural Experiment Station from the middle of July until late in 
October. Thirty-nine farms on which were grown 192.5 acres of early sweet 
corn were visited. Total damage amounting to $11,320, or an average of $58.80 
per acre, was reported. Thirty-seven growers having a total of 32.5 acres of 
late sweet corn experienced a net loss of $850, or an average of $26.15 per acre. 
The borer population count, made during October, included the same towns in 
which a similar survey had been made in 1932. A large increase in borer popu- 
lation was indicated. With the exception of two towns, an average annual 
increase of 100 percent was observed. The survey was made in sections adjacent 
to New London, Glastonbury, and Milford. Connecticut's 1934 spring corn 
borer clean-up, under the supervision of the State Agricultural Experiment 
Station, began on April 18 and was concluded late in May. Twenty-one men, 
each equipped with a light truck, were assigned to patrol every road in the 
State to locate any fields or lots containing cornstalks. A few prosecutions 
under the Connecticut General Statute were necessary to secure the complete 
destruction of the stubble and stalks observed in the course of the survey. 
There were no scouting activities under Federal supervision for the purpose 
of determining the absence or presence of the borer in territory outside the 
previously regulated zones. The only field-inspection work reported to the 
Bureau was that performed under the auspices of the Wisconsin Department 
of Agriculture. Specimens of the borer submitted for identification by the 
Wisconsin authorities indicate that corn borer larvae were recovered during 
the summer of 1933 in the following townships of the State: Liberty Grove, 
Sevastopal, and Sturgeon Bay, Door County; West Kewaunee and Carlton, 
Kewaunee County; Two Rivers, Manitowoc County; Herman, Sheboygan 
County;- Calumet, Fond du Lac County; Germantown, Washington County; 
Mequon, Ozaukee County; Granville and Milwaukee, Milwaukee County; 
Caledonia, Racine County; and Somers and Pleasant Prairie, Kenosha County. 
Infestations previously had been found in Manitowoc, Sheboygan, and Racine 
Counties; otherwise, the collections represented first-record finds in the respective 
counties. With the exception of the infestations in Fond du Lac and Washington 
Counties, all first-record finds were in townships bordering on Lake Michigan, 
or contiguous to coastal townships. Infestations were discovered in the north- 
ernmost and southernmost townships bordering on the lake, indicating a wide 
range of infestation along the lake front. 
PINK BOLLWORM 
The release of the Salt River Valley of Arizona from the quarantine enforced 
to prevent the spread of the pink bollworm (Pectinophora gossypiella Saund.), 
progress in the extermination of the recent Florida outbreak, and the discovery of 
the insect in Georgia and in additional sections of Florida, New Mexico, and Texas, 
were the most important developments of the year in the pink bollworm situa- 
tion. They indicate, on the one hand, the practicability and effectiveness of 
the suppressive measures now in use for accomplishing eradication, but, on the 
other hand, the continuous danger of reinfestation from Mexico and other parts 
of the world. 
The new findings involve 1 county in Florida, 3 in Georgia, 2 in New Mexico, 
and 8 in Texas. As the infestation is light, there is no cause for undue alarm,
