Sex Peptide Causes Mating Costs in Female Drosophila melanogaster
Conflicts between females and males over reproductive decisions are common . In Drosophila, as in many other organisms, there is often a conflict over how often to mate. The mating frequency that maximizes male reproductive success is higher than that which maximizes female reproductive success . In addition, frequent mating reduces female lifespan and reproductive success , a cost that is medi...
متن کاملSelective Mating in Drosophila Melanogaster.
LTHOUGH DARWIN (1871) believed that sexual selection was quite dis-A tinct from natural selection, the modern definitions of natural selection (HALDANE 1932; HUXLEY 1938, 1942) include the mating process among the forces of natural selection. DARWIN'S emphasis on the importance of male competition and the preferences of the females in sexual selection has been shown to have been misplaced in mo...
متن کاملRegulation of onset of female mating and sex pheromone production by juvenile hormone in Drosophila melanogaster.
Juvenile hormone (JH) coordinates timing of female reproductive maturation in most insects. In Drosophila melanogaster, JH plays roles in both mating and egg maturation. However, very little is known about the molecular pathways associated with mating. Our behavioral analysis of females genetically lacking the corpora allata, the glands that produce JH, showed that they were courted less by mal...
متن کاملAconitase and Developmental EndPointsasEarly IndicatorsofCellularToxicity Induced by Xenobiotics in Drosophila Melanogaster
Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system. Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...
متن کاملSex Differences in Drosophila melanogaster Heterochromatin Are Regulated by Non-Sex Specific Factors
The eukaryotic genome is assembled into distinct types of chromatin. Gene-rich euchromatin has active chromatin marks, while heterochromatin is gene-poor and enriched for silencing marks. In spite of this, genes native to heterochromatic regions are dependent on their normal environment for full expression. Expression of genes in autosomal heterochromatin is reduced in male flies mutated for th...
