Behaviour of male oriental fruit moth, Grapholita molesta, in overlapping sex pheromone plumes in a wind tunnel
(1996) In Entomologia Experimentalis et Applicata 79(1). p.51-59- Abstract
The behaviour of Grapholita molesta (Busck) (Lepidoptera: Tortricidae) males was studied in overlapping sex pheromone plumes in a wind tunnel. The ultimate aim of the study was to assess the effect of different treatments on male behaviour and consider the observed changes within the context of the suggested mechanisms underlying mating disruption. Two baits were placed either in series or parallel using both synthetic pheromone blends and female extracts. One bait, the reference containing (Z)-8-dodecenyl acetate/(E)-8-dodecenyl acetate/(Z)-8-dodecenol in a ratio of 100/6/10 was kept constant at a dose of 100 μg of the main component, giving a composition and a release rate close to that of a female. The dose of the other bait varied... (More)

One bait, the reference containing (Z)-8-dodecenyl acetate/(E)-8-dodecenyl acetate/(Z)-8-dodecenol in a ratio of 100/6/10 was kept constant at a dose of 100 μg of the main component, giving a composition and a release rate close to that of a female. The dose of the other bait varied between 0.1 and 100 times the concentration of the reference and was a mixture of one, two or three pheromone components. Males clearly discriminated between different blends and doses in the overlapping plumes, for regardless if the lures were presented in series or in parallel they followed the complete plume. Complete suppression of the response to the reference was only achieved with 300 μg of the optimal three-component blend on the other lure. When tested singly, a bait consisting of Z8-12:OAc/E8-12:OAc/Z8-12:O Hin a 100/0.2/0.4 ratio, attracted a high proportion of the males when placed 75 cm upwind of the male release site, but no males from 150 cm. Our data suggest that complete pheromone blends should be more effective than any incomplete blends in mating disruption formulations for G. molesta.
