Summary

Survival at various low temperatures and various exposure durations was quantified using regression models which calculate two parameters for six hexapod species: the temperature that cause no significant mortality during prolonged exposure was called upper limit of cold injury zone (ULCIZ). The difference between ULCIZ and the exposure temperature was defined as temperature effective in cold injury. The product of exposure duration and temperature effective in cold injury represents the acquired (accumulated) dose of a stressor, i.e. chilling, and is called sum of injurious temperatures, expressed in degree-days. The authors calculated the parameter for six hexapod species ranged from -17 deg C (diapausing overwintering moth pupae) to 11 deg C (tropical cockroach).
