Feeding and survival in parasitic wasps : sugar concentration and timing matter

  title={Feeding and survival in parasitic wasps : sugar concentration and timing matter},
  author={Gitta Siekmann and Brigitte Tenhumberg and Michael A. Keller},
Sugar consumption can increase the longevity and lifetime fecundity of many species of parasitic wasps. Consequently, for these insects the availability of sugar sources in the field is important for their reproductive success. As sugar sources can be highly variable in quantity, space and time, the chances of finding a sufficient amount of sugar to increase longevity might be very low. Therefore, the reward from a single feeding event can be critical for the forager’s fitness. We measured the… CONTINUE READING
