Winter dormancy in Ernobius abietis F. (Col., Anobiidae) studied in relation to cold hardiness
Journal of Applied Entomology - Zeitschrift für angewandte Entomologie 119 (4), 523-525
Abstract: Hibernating larvae of E. abietis lowered their supercooling points from -11.8°C in September to -25.6°C in January and adults from -12.7 to -25.7°C due to the state of winter dormancy which is mainly controlled by temperature. Only under low enviromental temperatures in autumn and winter did the overwintering specimens develop their cold hardiness. During favourable temperatures, hibernating larvae activate easily and continue their development despite the day length. Winter dormancy in adults seems to be induced by photoperiodical conditions.
