Table 5 Minimal adequate models explaining the effects of species, sexa, and treatment on the body composition of three Ceratitis species estimated using general linear models

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 to account for body size. Significant effects (P < 0.05) are indicated by bold type
  2. aSex was not included in the initial model for carbohydrates due to low sample size for males in some treatments
