Abstract:

various concentrations of carbaryl, DDT, disuIfoton, endosulfan, parathion, and Zectran® (4-dimethylamino- 3,5-xylyl menthylcarbamate) were evaluated by the continuous exposure method to obtain base line toxicity data for 2 field-collected populations of Epitrix hirtipennis (Melshcimer) .

The 2 populations exhibited a similar response to all insecticides, indicating little variability between populations. Parathiou was the fastest acting toxicant, with Zectran giving rapid kill at a low concentration, 0.0005%. Log-time probit-mortality regression lines reflected an increased tolerance to DDT by the beetle. The data serve as base lines (or future studies.
