Comparative chlorpyrifos susceptibilities were examined in male adults and 5th-instar larvae between resistant and susceptible populations of the Summer Fruit Tortrix, Adoxophyes orana fasciata. The susceptibilities were similar and parallel in both stages in each population. Monitoring of chlorpyrifos resistance is possible by treating male adults captured in sex-pheromone traps using a bodydipping method.
