Relevance of plant volatiles to sex pheromone in luring aphids in the field
Entomologia Sinica 7 (2), 178-184
Abstract: Outdoor trials were made to test the responses of male aphids to pheromone lures in fields with different host-plants, in order to know whether host-plants would affect catches of males to pheromone lures. In peach orchard, males of three aphid species, i.e. Myzus persicae, Hyalopterus amygdali and Rhopalosiphum nymphaeae, were found in traps baited with aphid sex pheromone nepetalactone and nepetalactol. The most numerous numbers was M. persicae and it was also attracted by plant-derived nepetalactone alone in peach orchard and cabbage garden. Schizaphis graminum males were caught in water traps in wheat field. In apple orchard, males of two aphid species, Aphis citricola and Sappaphis sinipiricola were caught in significantly larger numbers in the pheromone traps than in the control traps. Field study indicated that the sex pheromone of H. amygdali comprises either one or both of nepetalactone and nepetalactol, and nepetalactone may be one component of sex pheromones of A citricola and S sinipiricola. Another field trial had shown that catches were increased if volatiles from a steam-distilled extract of peach leaves were released simultaneously with nepetalactone. Elec-troantennograms (EAGs) were recorded from males of M. persicae to volatiles of peach leaves and buds.
