... across the gut epithelia. It has recently been suggested that this imbalance is at least partly caused by a cold-induced disruption of epithelial barrier function. Here, we aimed to test this hypothesis in the migratory locust ( Locusta migratoria ). First, chill tolerance was quantified by exposing...

... quickly, and better maintained hemolymph K + balance in the cold. The improvements in chill tolerance coincided with increased Malpighian tubule fluid secretion and better maintenance of K + secretion rates in the cold, as well as reduced rectal K + reabsorption in cold-acclimated flies. To test whether...

...Mads Kuhlmann Andersen; Heath A. MacMillan; Andrew Donini; Johannes Overgaard ABSTRACT Insect chill tolerance is strongly associated with the ability to maintain ion and water homeostasis during cold exposure. Maintenance of K + balance is particularly important due to its role in setting the cell...

... of extracellular ion and water homeostasis, leading to chill injury and eventually death. Chill-tolerant species are characterized by lower hemolymph [Na + ] than chill-susceptible species and this lowered hemolymph [Na + ] is suggested to improve ion and water homeostasis during cold exposure. It has therefore...

...V. Koštál; J. Vambera; J. Bastl SUMMARY Three acclimation groups [i.e. non-diapause (LD), diapause (SD) and diapause, cold-acclimated (SDA)] of the adult bugs Pyrrhocoris apterus differed markedly in their levels of chill tolerance. Survival time at a sub-zero, but non-freezing, temperature of –5...
