Differential Cold Tolerance on Immature Stages of Geographically Divergent Ceratitis capitata Populations.

ABSTRACT: Cold tolerance of adult medflies has been extensively studied but the effect of subfreezing temperatures on the immature stages remains poorly investigated, especially as far as different populations are regarded. In this study, we estimated the acute cold stress response of three geographically divergent Mediterranean fruit fly populations originating from Greece (Crete, Volos) and Croatia (Dubrovnik) by exposing immature stages (eggs, larvae, pupae) to subfreezing temperatures. We first determined the LT₅₀ for each immature stage following one hour of exposure to different temperatures. Then eggs, larvae and pupae of the different populations were exposed to their respective LT₅₀ for one hour (LT₅₀ = -11 °C, LT₅₀ = -4.4 °C, LT₅₀ = -5
