In this study, the FF-IPM team explored the interplay between the invasion process in the northern hemisphere and cold tolerance of geographically isolated populations of Ceratitis capitata by determining (a) the response to acute cold stress survival of adults, and (b) the supercooling capacity (SCP) of immature stages and adults. The results revealed that geographically isolated populations of the northern Hemisphere to acute cold stress,
respond differently. For SCP, the results revealed that there is little to no correlation between SCP and climate variables of the areas where C. capitata populations originated. These data provide novel insights into thermal biology of medfly and generate important data for predictive population modeling to estimate range expansion of
this notorious pest into cooler more temperate areas of Europe.
