Caterpillars use developmental plasticity and diet choice to overcome the early life experience of nutritional imbalance

Nutritional conditions experienced during early growth have important implications for the lifetime fitness of herbivores in nutritionally heterogeneous environments. We investigated the early life effects of imbalanced nutrient intake on key fitness components and how such effects can be overcome i... Full description

description: Nutritional conditions experienced during early growth have important implications for the lifetime fitness of herbivores in nutritionally heterogeneous environments. We investigated the early life effects of imbalanced nutrient intake on key fitness components and how such effects can be overcome in a generalist leaf-feeding lepidopteran caterpillar, Spodoptera litura. Over the fifth larval instar, caterpillars were pretreated on one of three diets that varied in protein and carbohydrate content (p35:c7, p21:c21 or p7:c35; % dry mass). After moulting to the sixth instar, they were transferred to one of three no-choice diets (p35:c7, p21:c21 or p7:c35) or a food choice where they received two nutritionally complementary diets (p35:c7 versus p7:c35). Approximately 80% of caterpillars that had been protein-deprived (p7:c35) during the fifth instar moulted to the seventh instar and developed into heavier pupae than those pupating after the sixth instar. The threshold body mass for...
