Sex-Linked Pheromone Receptor Genes of the European Corn Borer, Ostrinia nubilalis, Are in Tandem Arrays
BACKGROUND Tuning of the olfactory system of male moths to conspecific female sex pheromones is crucial for correct species recognition; however, little is known about the genetic changes that drive speciation in this system. Moths of the genus Ostrinia are good models to elucidate this question, since significant differences in pheromone blends are observed within and among species. Odorant re...
متن کاملSex Pheromone Receptor Specificity in the European Corn Borer Moth, Ostrinia nubilalis
BACKGROUND The European corn borer (ECB), Ostrinia nubilalis (Hubner), exists as two separate sex pheromone races. ECB(Z) females produce a 97ratio3 blend of Z11- and E11-tetradecenyl acetate whereas ECB(E) females produce an opposite 1ratio99 ratio of the Z and E isomers. Males of each race respond specifically to their conspecific female's blend. A closely related species, the Asian corn bore...
متن کاملRole of neuropeptides in sex pheromone production in moths.
Sex pheromone biosynthesis in many moth species is controlled by a cerebral neuropeptide, termed pheromone biosynthesis activating neuropeptide (PBAN). PBAN is a 33 amino acid C-terminally amidated neuropeptide that is produced by neuroendocrine cells of the subesophageal ganglion (SEG). Studies of the regulation of sex pheromone biosynthesis in moths have revealed that this function can be eli...
متن کاملNucleotide diversity in Silene latifolia autosomal and sex-linked genes.
The plant Silene latifolia has separate sexes and sex chromosomes, and is of interest for studying the early stages of sex chromosome evolution, especially the evolution of non-recombining regions on the Y chromosome. Hitch-hiking processes associated with ongoing genetic degeneration of the non-recombining Y chromosome are predicted to reduce Y-linked genes' effective population sizes, and S. ...
متن کاملGenetic variation in the strongly canalized sex pheromone communication system of the European corn borer, Ostrinia nubilalis Hübner (Lepidoptera; Pyralidae).
The major difference in pheromone production between the so-called E and Z strains of the European corn borer Ostrinia nubilalis is controlled by two alleles at a single autosomal locus. E-strain females produce an (E)-11-tetradecenyl acetate pheromone with 1-3% of the Z isomer, whereas Z-strain females produce the opposite blend. In laboratory-reared insects we found that F1 females produced, ...
