Overwintering larvae of the beetle,Dendroides canadensis, from northern Indiana were able to survice freezing at temperatures down to −28°C. During a late winter thaw or upon warm acclimation the larvae became freeze susceptible, but cold acclimation or acclimatization restored freeze tolerance. Concentrations of the cryoprotectants glycerol and sorbitol, ice nucleating agents (probably proteins) and thermal hysteresis proteins increase in the autumn, peak in winter and decline in spring. These… CONTINUE READING
