Abstract

The sex pheromone was extracted from sex pheromone glands of virgin female moths of P. orienta by n-hexane. The sensitive reaction of male moths antenna to the crude sex pheromon was detected by GC-EAD and the components of the sex gland extracts that consistently elicited antennal responses were identified by GC-MS. The results indicated that male moths antenna had sensitive reaction to two components of the extracts, which were Z-9-Octadacenal and Z-9-Octadacenol. In field trials, traps baited with either Z-9-Octadacenal or Z-9-Octadacenol alone caught a similar amount of male moths, which meant that Z-9-Octadacenal and Z-9-Octadacenol were the main components of the sex pheromone of Parocneria orienta. the combination of Z-9-Octadacenal and Z-9-Octadacenol in 1:9 or 1:9 ratio caught more males than single component traps.
