Innervation and neural regulation of the sex pheromone gland in female Heliothis moths.
Female Heliothis moths normally produce their species-specific male attractant (sex pheromone blend) during scotophase, and this production is stimulated by pheromone biosynthesis activating neuropeptide (PBAN), presumably carried in the hemolymph. Several lines of evidence indicate that the central nervous system plays another critical role in this regulation. Pheromone biosynthesis was induce...
متن کاملSugar feeding via trehalose haemolymph concentration affects sex pheromone production in mated Heliothis virescens moths.
Long-distance, female-produced sex pheromones are widespread among moths. Larval feeding provides most of the nutrients for development of these insects but is not thought to influence the de novo production of the fatty-acid derived compounds used as pheromones by most species. Feeding on plant nectar (sugar) by adult moths is important for increasing female fitness and also for the pollinatio...
متن کاملIdentification of the sex pheromone components secreted by female moths of Peridroma saucia (Noctuidae: Noctuinae).
The variegated cutworm, Peridroma saucia Hübner, is a lepidopteran pest to a large number of crops in Canada, the United States, and Europe. It was probably naturalized in Japan in the 1970s. The pheromone glands of the female moth include two components with electroantennographic activity in a ratio of 3:1. GC-MS analyses of pheromone extracts untreated and treated with dimethyl disulfide reve...
متن کاملInhibition of sex pheromone production in female lepidopteran moths by 2-halofatty acids.
Inhibition of sex pheromone production has been observed after topical treatment of pheromonal glands with DMSO solutions of 2-bromohexadecanoic acid, in three lepidopteran insects: Spodoptera littoralis, Thaumotopoea pityocampa, and Bombyx mori. It has been shown that this effect was brought about by action on the reductases and acetyltransferases of the final steps of the pheromones biosynthe...
متن کاملGenetics 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...
