PEST SURVEY


Vol. 16 Supplement to ITo. 4 June 15, 1936



RESULTS OF EUROPEAN CORN BORER SURVEYS IN THIRTEEI1' SELECTED COUNTIES, 1935

By L. H. Worthley, In Charge,
Japanese Beetle Control Division,
Bureau of Entomology and Plant Quarantine,
U. S. Department of Agriculture.


Results of a survey to determine the degree of European corn borer
infestation over a considerable portion of the infested area were reported
by A. M. Vance, of the Division of Cereal and Forage Insect Investigations,
in the Insect Pest Survey Bulletin vol. 15, supplement to no. 9 (October
1935).

As a part of a corn borer survey performed by men employed under
Works Progress Administration funds, working under the supervision of the
Japanese Beetle Control Division, surveys were made in 13 counties in Maine,
Michigan, New Hampshire, New Jersey, and Vermont that were not covered by the
survey organized by the Division of Cereal and Forage Insect Investigations.

In general, the W. P. A. survey was made in fields selected at random
in each township of the counties covered. Twenty-five consecutive corn
plants in one row near the center of each quarter of the field were examined
for infestation, a total of 100 plants being examined in each field. Ton of
the plants showing infestation were dissected to determine the average
number of corn borers per infested plant.

Data concerning the 13 nonduplicated counties supplement that pre-
viously reported, and are tabulated for the information of interested State
officials.

Townships in the respective counties surveyed are listed, together
with the number of fields examined, acres surveyed, percentage of plants
found infested, and the average number of corn borers per 100 plants examined.
County summaries are included. There are, however, no regional averages, as
these data are incomplete for continuous areas, and must be considered in
conjunction with previously published results if regional averages are
desired.
