Immune investment impairs growth, female reproduction and survival in the house cricket, Acheta domesticus

摘要: We investigated whether an immune response is associated with growth, female reproduction and survival costs in the house cricket. Using different intensities of challenge (implantation one piece nylon (1N) two nylons (2N), their respective sham-challenge control groups) body size exoskeleton thickness as variables, growth were determined for both sexes. A similar methodology was followed costs, which egg number size, measured variables. It also mated virgin females showed responses. Body decreased but only 2N treatment. Exoskeleton increased groups 1N group group. Egg more by groups. The largest at end experiment. In these females, died first 1N, sham Finally, a lower than females. These results are consistent ecological immunity theory. discovery exoskeleton-related injury may have important implications experimental design studies cost immunity.
