Fig. 3. Size-mediated effects of dietary conditioning and parasitism by Cotesia congregata on consumption of a protein diet and a carbohydrate diet by the host Manduca sexta given a dietary choice. Results for individual larvae are shown with regression lines depicting the relationships between size and consumption for each treatment level. (A) Effects of conditioning on carbohydrate consumption. For larvae conditioned on the protein diet (triangles), consumption=0.2091xfinal mass; for larvae conditioned on the carbohydrate diet (circles), consumption=0.6820xfinal mass. (B) Effects of conditioning on protein consumption. For larvae conditioned on the protein diet (triangles), consumption=1.3072xfinal mass; for larvae conditioned on the carbohydrate diet (circles), consumption=0.9861xfinal mass. (C) Effects of parasitism on carbohydrate consumption. For parasitized animals (triangles), consumption=0.2091xfinal mass; for normal animals (circles), consumption=0.9405xfinal mass. (D) Effects of parasitism on protein consumption. For parasitized animals (triangles), consumption=1.3072xfinal mass; for normal animals (circles), consumption=2.3149 (final mass). The results of the ANCOVAs are shown in Table 3.
