Survival and reproduction of heat-acclimated sitophilus granarius (coleoptera, curculionidae) at a moderately high temperature
1977
Gonen, M.
S. granarius was acclimated to high temperatures by exposing adults to 32° for 14 days and by continuously rearing at 30° for four generations. The insects were then exposed for one week to 35° and mortality and number of offspring produced per live female were followed over 4 weeks. S. granarius reared at 30° did not show any signs of acclimation judging by mortality data, nor by reproduction data. Insects acclimated by prior exposure to 32° showed some degree of acclimation in terms of mortality, but not in the number of offspring produced after exposure to 35°. The acclimation procedures themselves did not affect reproduction or survival.
