A Fungal Metabolite as the Male Wing Gland Pheromone of the Bumble-Bee Wax Moth, A phom ia sociella L.

Abstract

3,4-Dihydro-9-hydroxy-3-m ethylisocoum arin [R (-) - mellein] was identified as the major component of themale wing gland pheromone of the bumble-bee wax moth, Aphomia sociella L. (Pyralidae, Galleriinae). The presence of Aspergillus ochraceus Wilhelm, a mellein producing microorganism, was detected in the intestinesof last-instar larvae andinbumble-bee nests. Arguments for a new type of insect-fungus relationsip are presented. © 1987, Walter de Gruyter. All rights reserved.
