Abstract

The influence of posttreatment temperature on the toxicity of 6 insecticide was investigated on a susceptible and 2 resistant strains of Musca domestica L: The toxicity of dimethoate, parathion, and Isolan^® (l-isopropyl-3-methyl-5-pyrazolyl dimethylcarbamate) was unaffected by temperature within the range of 15° and 25°C. Bioresmethrm, lindane and CP 47412 (1, 1-di(p-chlorophenyl)-2, 2-dichlorocyclopropane) manifested greater toxicity at 15°C. This effect was more pronounced in the resistant strains but did not reduce resistance more than 1.6-fold. It is suggested that temperature within the range tested has no significant influence on potential resistance in the field.
