Antifreeze effect of thermal hysteresis agents protects highly supercooled insects

Abstract

Insects that are cold-hardy but sensitive to freezing survive at low temperatures due to their capacity for supercooling—their supercooling points are below −25 °C. In addition to polyols, these insects produce proteinaceous thermal hysteresis antifreeze agents reported to prevent growth of ice crystals down to ∼−10 °C, thus stabilizing the supercooled… (More)
