Genetics of sex pheromone blend differences between Heliothis virescens and Heliothis subflexa: a chromosome mapping approach.
Males of the noctuid moths, Heliothis virescens and H. subflexa locate mates based on species-specific responses to female-emitted pheromones that are composed of distinct blends of volatile compounds. We conducted genetic crosses between these two species and used AFLP marker-based mapping of backcross families (H. subflexa direction) to determine which of the 30 autosomes in these moths conta...
متن کاملCHEMICAL ECOLOGY Male and Female Antennal Responses in Heliothis virescens and H. subflexa to Conspecific and Heterospecific Sex Pheromone Compounds
To determine whether Heliothis virescens and H. subflexa, two closely related sympatrically occurring species, differ in their antennal responses to conspeciÞc and heterospeciÞc pheromone compounds, we recorded electroantennogram (EAG) responses of male and female antennae of both species to eight different compounds loaded on Þlter paper dispensers. If antennal responses were found to differ i...
متن کاملGenes encoding candidate pheromone receptors in a moth (Heliothis virescens).
The remarkable responsiveness of male moths to female released pheromones is based on the extremely sensitive and selective reaction of highly specialized sensory cells in the male antennae. These cells are supposed to be equipped with male-specific receptors for pheromonal compounds, however, the nature of these receptors is still elusive. By using a combination of genomic sequence analysis an...
متن کاملPlant odorants interfere with detection of sex pheromone signals by male Heliothis virescens
In many insects, mate finding relies on female-released sex pheromones, which have to be deciphered by the male olfactory system within an odorous background of plant volatiles present in the environment of a calling female. With respect to pheromone-mediated mate localization, plant odorants may be neutral, favorable, or disturbing. Here we examined the impact of plant odorants on detection an...
متن کاملSpecificity of the Receptor for the Major Sex Pheromone Component in Heliothis virescens
In a previous study, the Drosophila melanogaster OR67d(GAL4);UAS system was used to functionally characterize the receptor for the major component of the sex pheromone in the tobacco budworm, Heliothis virescens Fabricius (Lepidoptera: Noctuidae), HvOR13. Electrophysiological and behavioral assays showed that transgenic flies expressing HvOR13 responded to (Z)-11-hexadecenal (Z11-16:Ald). Howev...
