Female sex pheromone of glossosphecia romanovi (Lepidoptera: Sesiidae): Identification and field attraction

Abstract

In field screening tests of synthetic pheromone candidates for Japanese sesiid species, a mixture of (3Z,13Z)-octadecadien-l-ol and (3Z,13Z)- octadecadienyl acetate successfully attracted male moths of Glossosphecia romanovi, a harmful pest of vine trees. The GC-EAD and GC-MS analyses of the pheromone gland extract revealed that the female moths produced the alcohol and acetate in a ratio of about 20:1, in addition to three other minor structure-related components.
