Sexual selection, sexual isolation and pheromones in Drosophila melanogaster strains after long-term maintaining on different diets

摘要: Evolution of reproductive isolation may be a consequence variety signals used in courtship and mate preferences. Pheromones play an important role both sexual selection isolation. The abundance pheromones Drosophila melanogaster depend on different environmental factors, including diet. aim this study was to ascertain which degree principal affect D. melanogaster. We strains reared for 14 years four substrates: standard cornmeal substrate those containing tomato, banana carrot. have previously determined that long-term maintaining these dietary resulted differences their cuticular hydrocarbons profile (CHs). In work, we tested the level between aforementioned strains. found high levels cis-vaccenyl acetate, 7-pentacosene 7,11-nonacosadiene strain carrot affected individual attractiveness influenced flies banana. Based results, diets, contribute, behaviour via effects pheromones.
