Fig. 3. Multidimensional profiles illustrating the effects of blood protein nitrogen trehalose levels (mg per insect) on biomass of C. congregata, emerged and non-emerged from M. sexta larvae maintained over the fourth and fifth stadia on a chemically defined artificial diet having varying ratios of casein (C) and sucrose (S). (A,C) Three-dimensional models for emerged and non-emerged parasite biomass, respectively. See text for model specifications and details. (B,D) Contour maps show actual emerged and non-emerged biomass, respectively. Blood metabolite levels are indicated for individual larvae on the various diets.
