Differences in mortality at subzero temperatures between one and two generation population. a Pupae, b direct developing 5th instar larvae, and c cold-acclimated diapausing larvae. Bars represent the mean mortality in each group ± SE. Significance between strains at various subzero temperatures was determined using two GLMs followed post-hoc by Tukey’s HSD where * = p < 0.05, ** = p < 0.01, and **** = p < 0.0001
