Egg incubation temperature differently affects female and male hatching dynamics and larval fitness in a leafhopper.

摘要: Temperature effects on ectotherms are widely studied particularly in insects. However, the life-history of temperature experienced during a window embryonic development, that is egg stage, have rarely been considered. We simulated fluctuating temperatures and examined how this affects operational sex ratio (OSR) hatching as well nymph adult fitness leafhopper, Scaphoideus titanus. Specifically, after warm or cold incubation we compared males females dynamics with their consequences course time, body size, weight, developmental rate two populations, all reared same posthatching temperature. Males eggs respond differently, more sensitive to variation The different responses both sexes dynamic hatchings weaker protandry incubation. Temperatures by complex development. Later nymphal instars hatched from exposed were larger bigger but populations was not affected. Our study demonstrates could affect development an insect may be critical for population growth.
