Description: Selected carbamate, chlorinated hydrocarbon, organophosphorous, and pyrethroid insecticides were tested on six Choristoneura species: conflictana(Walker), fumiferana (Clemens), lambertiana ponderosana Obraztsov, occidentalis Freeman, pinus Freeman, and viridis Freeman. When probit regression lines were compared by likelihood ratio test, the hypotheis of equality was uniformly rejected. The hypothesis of equality was uniformaly rejected. The hypothesis of parallelism was accepted for some chemicals within each insecticide class except the chlorinated hydrocarbon. These results suggest that extrapolating the response of one species to another species should be avoided.
