ESR update - Dormancy is an important adaptation that allows many insects to cope with adverse environmental conditions. The fruit fly Drosophila melanogaster enters an ovarian reproductive dormancy as a response to short photoperiods and low temperatures. D. melanogaster originated in sub-Saharan Africa and dormancy is believed to have evolved during the migration out of that continent and the colonization of temperate regions. According to literature, during dormancy, adult females have immature ovaries and show depressed metabolism, delayed senescence and elevated stress resistance.
