A Prelimiary Study of the Identification of Components of Sex Pheromone from Parocneria orienta Chao and its Trapping Effects in the Field

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.
