Abstract Cold tolerance of overwintering nymphs of a cockroach, Periplaneta japonica, was examined in terms of the supercooling capacity and lower lethal temperature. The supercooling point of overwintering nymphs fell in a relatively narrow range of temperature from -6 to -9°C and no correlation was observed between the supercooling point and body size. In the temperature range from -5 to -8°C, a significant proportion of cockroaches could tolerate a 12 hr period of tissue freezing. The freeze… Expand
