Predator deterrence by mandibular gland secretions of bees (Hymenoptera: Apoidea).

abstract：:The analyses of virgin female sex pheromone gland extracts and gland volatiles by GC, GC-EAD and GC-MS, followed by field trapping experiments, have identified (E)-9-dodecenyl acetate (E9-12∶Ac) as the primary sex pheromone component of the purplestriped shootworm,Zeiraphera unfortunana.
