Table 3. Parametric Two-Way ANOVA to evaluate the effects of constant supply of water and honey on several life-history traits of Pachycrepoideus vindemmiae (Hymenoptera: Pteromalidae) reared on pupae of spotted-wing drosophila (Drosophila suzukii), throughout the parasitoid’s early and entire adulthood.
N = 11 (water), (14) honey, (10) water + honey, and (12) fasting. Each replicate was formed by one mated individual wasp.
