Pistachio twig borer, /Kermania/ /pistaciella /is an important pest of pistachio trees.We found thatoverwintering larvae of the Rafsanjan (Iran) population of /K/. /pistaciella/rely on maintaining a stably high supercooling capacity throughout the cold season. High cold tolerance during dormancy was not associated with accumulation of any low-molecular mass cryoprotective substances. The SCP sets the limit of cold tolerance in pistachio twig borer, meaning that high mortality of overwintering populations can be expected only in the regions or years where or when the temperatures fall below the average larval SCP (/i.e./ below -20°C). Partial mortality can be expected also when temperatures repeatedly drop close the SCP on a diurnal basis.
