Reproductive biology of the yellow-spotted longicorn beetle,Psacothea hilaris (pascoe) (Coleoptera: Cerambycidae). III. Identification of contact sex pheromone on female body surface.
A major component of female contact sex pheromone of the yellow-spotted longicorn beetle,Psacothea hilaris (Pascoe), was isolated from the elytra and identified as (Z)-21-methyl-8-pentatriacontene. The synthetic compound released the typical mating behavior including holding, mounting, and abdominal bending in males, although its activity was considerably lower than the extract of female elytra when treated on a gelatin capsule as an artificial female model.
