The following parameters were evaluated: mating success(ability to be chosen by females), number of copulations, and copula duration. Experiments were carried out using a fifteen-year old laboratory lineage with the occasional introduction of wild flies. Two groups of adult males fed a highprotein diet during their larval phase were given either a high-protein diet (based on Brewer’s yeast, concentration = 6.5g/100 ml) or a no-protein diet. Both groups of males were exposed to females fed either a high-protein diet or a noprotein diet and were subsequently evaluated for the parameters listed above. All experiments were conducted at 25°C,70% R.H. and with a photoperiod of L12:D12. The number of copulations was the only parameter affected by adult diet. Males fed a high-protein diet and exposed to females fed a no-protein diet had a greater number of copulations compared with males fed a no-protein diet. |
