Abstract The released pheromone and the glandular lipids, labeled with [14C]acetate, were analyzed fromChoristoneura orae andChoristoneura fumiferana budworm moths by thin-layer chromatography and autoradiography. Radiolabeled lipids in the gland appeared to be identical in the two moths with both insects containing high amounts of 11-tetradecenyl acetates. In contrast, theC. orae moths released primarily labeled acetate ester and alcohol, and the spruce budworm moths (C. fumiferana) labeled aldehyde consistent with the known composition of their respective pheromones. The levels of the enzymes responsible for converting the acetate ester into aldehyde were found to be significantly lower in gland extracts fromC. orae moths than fromC. fumiferana moths. These results implicate an acetate esterase and an alcohol oxidase in controlling the composition of the pheromone blend released from closely related budworm species.
