Antennae are often considered to be the nostrils of insects. Here, we sequenced the transcriptome of the pheromone gland-ovipositor complex of Helicoverpa assulta and discovered that an odorant receptor (OR) gene, HassOR31, had much higher expression in the ovipositor than in antennae or other tissues. To determine whether the ovipositor was involved in odorant detection, we co-expressed HassOR31 and its co-receptor, HassORco, in a Xenopus oocyte model system, and demonstrated that the OR was responsive to 12 plant odorants, especially Z-3-hexenyl butyrate. These odorants elicited electrophysiological responses of some sensilla in the ovipositor, and HassOR31 and HassORco were co-expressed within ovipositor sensilla. Two oviposition preference experiments showed that female moths lacking antennae still preferentially selected oviposition sites containing plant volatiles. We suggest that the expression of HassOR31 in the ovipositor of H. assulta helps females to determine precise egg-laying sites in host plants.

The gorse pod moth Cydia succedana was released in New Zealand from Europe in 1992 as a biological control for gorse (Ulex europaeus) In this study the behavioural responses of the moth to lures containing different blends of plant volatiles identified from their host plants and through singlesensillum recordings were tested in a field trial at Chaneys Forest Canterbury Volatiles were placed on cotton wicks with or without the female sex pheromone of C succedana on rubber septa in delta traps Two different blends elicited behavioural responses indicated by trap catches Cydia succedana catches with the fourcomponent Blend 6pheromone lure were lower than with the pheromone alone The 10component Blend 4 lure caught more C succedana than any other blend when tested without the pheromone These results indicate the behavioural significance of host and nonhost plant volatiles and the relationship between the behaviourally active compounds and the profile of olfactory receptor neurons in C succedana
