Freeze-susceptible insects (those that die if frozen) must lower the freezing and supercooling points of their body fluids in winter. Although it is well known that many overwintering insects concentrate antifreezes such as polyols (glycerol, sorbitol, etc.) and/or thermal hysteresis proteins in the

Larvae of the Pyrochroid beetle Dendroides canadensis produce hemolymph antifreeze proteins (AFPs) as an adaptation to subzero overwintering temperatures. The AFPs are produced in early autumn in response to various environmental cues (short photoperiod, low temperature, short thermoperiod). The stu

## Abstract A thermal hysteresis producing antifreeze protein was isolated from larvae of the beetle, __Tenebrio molitor__. This is the first thermal hysteresis protein purified from an insect. The specific activity of the __Tenebrio__ antifreeze is somewhat greater than that of the fishes. The com
