✦ Synopsis

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 hemolymph, antifreezes have not previously been found in gut fluid.

Overwintering freeze-susceptible larvae of the Pyrochroid beetle Dendroides canadensis accumulated glycerol, sorbitol, and thermal hysteresis proteins 0 1984 ALAN R. LISS, INC.

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
