Drosophila melanogaster have reduced mating success after being exposed to starvation selection pressure that results in increased body weight. Many insect are capable of finishing their metamorphosis before larva reaches their final size. This results in smaller but viable adults. Previously, flies were put through a rescue protocol to reduce their size in efforts to increase mating. This method was not successful across all genetic lines of starvation resistant flies. We suspect that the increased cuticle hydrocarbon released by starvation resistance flies impacts their mating success. We will test this hypothesis by following a performing a pheromone exchange protocol.
