“…So far as we know, no freeze tolerant species has been found in these groups, and it appears that all mite species entirely depend on supercooling ability to survive exposures at low temperatures in their natural habitats (Cannon and Block, 1988;Sjursen and Sinclair, 2002;Sømme, 1981). In T. urticae, several studies examined the thermal requirements for development and reproduction (Bounfour and Tanigoshi, 2001;Naher et al, 2008;Praslicka and Huszar, 2004), and the environmental cues triggering reproductive diapause (Koveos et al, 1993;Kroon and Veenendaal, 1998;Veerman, 1977;. However, the thermal biology of this worldwide pest of economic importance has been poorly investigated.…”
