Journal ArticleDOI
Commensal bacteria play a role in mating preference of Drosophila melanogaster
Gil Sharon,Daniel L. Segal,John Ringo,Abraham Hefetz,Ilana Zilber-Rosenberg,Eugene Rosenberg +5 more
TL;DR: In this study, mating preference was achieved by dividing a population of Drosophila melanogaster and rearing one part on a molasses medium and the other on a starch medium and it was confirmed that symbiotic bacteria can influence mating preference by changing the levels of cuticular hydrocarbon sex pheromones.
Journal ArticleDOI
Female sexual receptivity is defective in juvenile hormone-deficient mutants of the apterous gene of Drosophila melanogaster.
TL;DR: The reduction in female receptivity in homozygousap strains, and heteroallelic combinations ofap mutations exhibited low receptivity is positively correlated with levels of juvenile hormone synthesized by their corpora allata.
Journal ArticleDOI
An Experiment Testing Two Hypotheses of Speciation
TL;DR: The results of this experiment and previous, related ones support the view that either genetic drift or selection is by itself sufficient to produce reproductive isolation as a pleiotropic by-product and help establish sexual isolation in Drosophila simulans.
Journal ArticleDOI
Bacteria-induced sexual isolation in Drosophila
TL;DR: It is hypothesize that bacteria-induced sexual isolation is caused by chemosensory cues, and changes in the profile of cuticular hydrocarbons, which function as sex pheromones are altered.
