Results of generalized linear model (GLZ) analyses investigating the effects of developmental acclimation temperature (20, 25, 30°C; ‘Acclimation’) on the absolute numbers of recaptured moths and the proportion of recaptured moths relative to the intermediate control group (25°C acclimation temperature). Data for laboratory-reared moth recapture rates were regarded as count data and analysed using GLZ assuming a Poisson distribution and an identity link function in SAS statistical software (Proc Genmod), with corrections for overdispersion. In all cases investigated, the effect of acclimation temperature was the categorical variable and recapture ratios or absolute number captured as the dependent variable at varying average field temperatures as a continuous variable. The Wald χ² was used to test for significant differences between acclimation groups. Significant effects are highlighted in bold font
