Male diet influence on male mating ability and progeny size in two sympatric species of Drosophila
Krishna M S
The amount and quality of nutrients consumed by organisms have a strong impact on fitness, life-history traits and reproduction. The balance between energy acquisition and expenditure is crucial to the survival and reproductive success of animals. Male diet has been examined in two sympatric Drosophila species, D.bipectinata and D.malerkotliana, to see how it affects male mating ability and progeny quantity. It was shown that males fed a high-protein diet inseminated more females and produced more progeny than males fed a high-carbohydrate diet or a control diet. D. malerkotliana has a much higher male mating ability and offspring output than D. bipectinata among sympatric species. As a result of these investigations in sympatric Drosophila species, it appears that dietary regimes have a considerable impact on male mating capacity and progeny production. Further protein rich diet increases male fitness in species of Drosophila.
