Acclimatization and the Thermal Death Point in Insects

Abstract

INSECTS, like other cold-blooded animals, are active over a range of temperature, limited below by the chill coma point, and above by the heat coma point (closely related to the thermal death point, that is, the upper lethal temperature, for they cannot recover from long periods of heat coma). On the whole, the heat coma point is higher for insects from warm regions, and the chill coma point is lower in those from cool regions.
