  • The ability of isolated Malpighian tubules from a freeze-tolerant insect, the New Zealand alpine weta (Hemideina maori), to withstand freezing was assessed by measuring post-freeze membrane potentials and rates of fluid secretion. The hemolymph of cold-acclimated Hemideina maori was found to contain relatively high concentrations of the cryoprotectants trehalose (>300 mmol l-1) and proline (41 mmol l-1). Survival of isolated Malpighian tubules was correspondingly high when a high concentration… CONTINUE READING
