LABOPATORY TESTS OF TOXICITY OF SOME ORGANIC COMPOUNDS
TO THE EUROPEAN CORN BORER, 1941-1943

Py D. D. (questel, Division of Cereal and Forage Insect Investigations,
and S. I. Gertler, Division of Insecticide Investigations

Laboratory investigations of organic compounds to establish
their toxicity to newly hatched European corn borer larvae have been
conducted in Toledo, Ohio, since early in 1938. Compounds that have
been tested in addition to those previously reportedl- are included
in this discussion.

The care and handling of larvae, moths, and eggs for these
tests and the technique employed in conducting them were the same as
described in the earlier report. All tests were run for 48 hours.
Cauliflower leaves were used as the feeding medium.

Materials were tested as sprays at a strength of 4 pounds per
100 gallons of water containing one-third pound of Areskap (sodium
monosulfonate of butylphenylphenol) as a wetting agent. Those materi-
als that gave high mortality with little or no feeding were retested
at the rate of 2 pounds or 1 pound per 100 gallons of water, or both.

The materials tested and the corn borer mortality obtained with
each are given in table 1.

Only four materials tested at 4 pounds per 100 gallons of water
were considered sufficiently toxic for retesting in the laboratory at
a concentration of 2 pounds per 100 gallons of water, and three of
these were retested at 1 pound per 100 gallons. None of the compounds
tested compared favorably with preparations of ground rotenone-bearing
roots containing 5 percent of rotenone, which cause practically 100
percent mortality when used at this concentration.
