Colonies of the honey bee, Apis melli/eTa L., showed variation in tolerance to the insecticides diazinon, propoxur, aldrin, and carbaryl. Tolerance to diazinon and propoxur was positively related to midgut mixed-function oxidase and glutathione transferase enzyme activities, but tolerance to aldrin was inversely related to these enzymes. Differences in tolerance to carbaryl were evident among colonies but were not related to enzyme activity levels. Linear regression models derived from these data may be used to predict colony tolerance from enzyme activity and may enable the selection of tolerant strains of bees that could maintain efficient pollination in areas of extensive insecticide use.
