Physiology of cold tolerance in the bark beetle, Pityogenes chalcographus and its overwintering in spruce stands

Journal of Insect Physiology, 2014
The seasonal development of physiological features underlying gradual acquisition of relatively high cold tolerance in overwintering adults of the bark beetles, Pityogenes chalcographus was described. Prior to overwintering, the beetles accumulated carbohydrate reserves in the form of glycogen and trehalose.

Zum Einfluß von Photoperiode und Temperatur auf die Entwicklung des Kupferstechers, Pityogenes chalcographus L. (Col., Scolytidae)

Forstwissenschaftliches Centralblatt, 1979
Durch Laborexperimente wurde festgestellt, das Jungkafer vonPityogenes chalcographus nach Abschlus ihrer Entwicklung in den Brutsystemen inaktiv bleiben, wenn sie sich bei 20° und Kurztagbedingungen entwickelt haben. Waren die Bruten bei 20° Langtagbedingungen ausgesetzt, so verlast nur ein Teil der Jungkafer die Brutstatten.
