Table 3 ANOVA and summary statistics for models fitted to data on the duration of the larval stage, duration of the pupal stage, pupal weight, survival to adult, development time to adulthood and adult resistance to desiccation and starvation of Anastrepha ludens reared on low yeast-high sucrose and high yeast-low sucrose content diets (Diet) treated with chlorogenic acid (C. acid).

  1. aPrior to model fitting, data on pupal weight and development time to adulthood were normalized by rank transformation. Data from all other response variables were modelled without transformation.
  2. bA mean model was fitted to data on the duration of the pupal stage (after reduction from a 2-factor interaction model), pupal weight (after reduction from a linear model), survival to adult and adult resistance to desiccation and starvation (after reduction from a quadratic model); a reduced linear model was fitted to data on development time to adulthood; a 2-factor interaction model was fitted to data on the duration of the larval stage.
  3. cVariation of the data around the fitted model.
