Relative male age, fertility, and competitive mating success in Drosophila melanogaster.
Female choice experiments were used to investigate the effect of relative male age on mating success in D. melanogaster. Experiments were conducted with a Canton-S (CS) strain, in which two virgin males of different ages (2, 4, or 8 days old) were offered to virgin females. Older males were found to be more successful under competitive conditions in another group of experiments, vermilion (v) m...
متن کاملSexual Experience Enhances Drosophila melanogaster Male Mating Behavior and Success
Competition for mates is a wide-spread phenomenon affecting individual reproductive success. The ability of animals to adjust their behaviors in response to changing social environment is important and well documented. Drosophila melanogaster males compete with one another for matings with females and modify their reproductive behaviors based on prior social interactions. However, it remains to...
متن کاملMale-mating Ability in Drosophila Melanogaster
The effect of full-sib inbreeding on competitive male-mating ability (CI8) in Drosophila melanogaster was investigated in two experiments. In the first, five inbred lines (with reserves) were assessed up to 18 generations. Linear inbreeding depression, of 5.9% per 10% increase in homozygosity, was observed. In a second experiment, 21 inbred lines were tested after three generations of full-sib ...
متن کاملVariation in the Male Pheromones and Mating Success of Wild Caught Drosophila melanogaster
Drosophila melanogaster males express two primary cuticular hydrocarbons (male-predominant hydrocarbons). These act as sex pheromones by influencing female receptivity to mating. The relative quantities of these hydrocarbons vary widely among natural populations and can contribute to variation in mating success. We tested four isofemale lines collected from a wild population to assess the effec...
متن کاملMating success associated with the white gene in Drosophila melanogaster
Characteristics of mating behavior in Drosophila melanogaster have been well-described, but the genetic basis for male-female mating success is largely unknown. Here we show that the white (w) gene, a classical eye color gene, is associated with mating success. 81.3 % of wild-type flies copulated within 60 minutes in the circular arenas, whereas few white-eyed mutants mated successfully. The w+...
