Résumé

The cold hardiness adaptations of natural and laboratory reared populations of the codling moth, Cydia pomonella, were examined. Hemolymph, gut, and whole body supercooling points, 24-h LT50s, polyhydroxy alcohol concentrations, hemolymph freezing points, and hemolymph melting points were determined. Nondiapausing colding moth larvae do not have appreciable levels of ice nucleators in the hemolymph or gut. Whole body supercooling points were higher than both the whole body and the hemolymph supercooling points, indicating the presence of chill sensitivity. Diapose disposed and diaposing larvae are studied during overwintering.
