摘要: The greater date moth (GDM), Aphomia sabella Hampson (Lepidoptera: Pyralidae: Galleriinae), is a serious pest of palms, Phoenix dactylifera. release volatiles from both males and females was investigated using sequential SPME/GC/MS analysis. Males complex mixture compounds in circadian rhythm during the night between 03:00 05:00 hr. Six were identified: benzaldehyde, sulcatol (6-methyl-5-hepten-2-ol), geranyl acetone [(E)-6,10-dimethyl-5,9-undecadien-2-one], phenylacetaldehyde, 2-phenylpropenal, (R)-fuscumol [(R)-(E)-6, 10-dimethyl-5, 9-undecadien-2-ol]. Benzaldehyde, sulcatol, found only trace amounts. These glands located forewing only. Small amounts acetoin 2,3-butanediol sporadically analyses females, these probably originate microorganisms. This first finding male-specific moths. GC/EAD with synthetic standards released by showed that female antenna stimulated all six compounds, while male responded to phenylacetaldehyde. A possible pheromonal role for suggested their EAD response them. However, trapping tests main screen cages laboratory or field did not reveal any significant behavioral responses males. Copulation observed presence palm tissue, thus suggesting sexual communication mating GDM moths occurs crown palms.
