Table 2 Analysis of deviance table for the final fitted parametric survival model that describes desiccation resistance of three Ceratitis species with respect to sex, temperature (Temp) and relative humidity (RH)

From: Physiological mechanisms of dehydration tolerance contribute to the invasion potential of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) relative to its less widely distributed congeners

  1. Initial body mass was included as a covariate in the model. Data were fitted to a Weibull hazard function. The analysis of deviance table was constructed using Type III likelihood ratio tests. Significant effects (P < 0.05) are indicated by bold type
