Carotenoids in 38 species of Lepidoptera have been examined qualitatively and quantitatively. Comparisons are made between cryptic and aposematic species, pupae and adult, dried and fresh material, males and females, and certain polymorphic species. Although some selective storage is demonstrated, Lepidoptera chiefly store the carotenoids present in their food plants unchanged. It was found that the Large White (Pieris brassicae), a toxic species, stored more carotenoids than the less toxic Small White (P. rapae) while ab. coerulea (P. brassicae) contained only 25 % of the carotenoids found in typical specimens.read more

Sequestration of defensive substances from plants by Lepidoptera.
TL;DR: The biochemical, physiological, and ecological characteristics of phytochemical-based defense systems that can shed light on the evolution of the widely developed sequestering lifestyles among the Lepidoptera are illustrated.

Gut loading to enhance the nutrient content of insects as food for reptiles: A mathematical approach
TL;DR: Diets and insects were analyzed for moisture, Ca, phosphorus, and vitamin A, and regression equations allow for the calculation of the optimum nutrient concentration for gut-loading diets.

Aposematic and cryptic Lepidoptera tested on the mouse
N.A. Marsh,Miriam Rothschild +1 more
TL;DR: Points of interest which emerged from this study include (i) Pieris brassicae is toxic whether or not the larval diet contains sinigrin and mustard oils; and (ii) a marked sexual dimorphism in toxicity is noted in several species.

Insect Nutrition: Current Developments and Metabolic Implications
TL;DR: Three decade s ago nutritional investigation of insects had developed to the point of describing complete qualitative dietar y requirements of several nonfastidious spe cies that readily accepted chemically defined diets, allowing individually deleted nutrients to be assessed in terms of growth and develop ment.

The chemical acceleration of the maturation process and its hormonal control in the male of the desert locust
TL;DR: Extirpation and implantation of the corpora allata have demonstrated that in the male these endocrine glands are in control of sexual maturation and some associated processes, such as the production of the epidermal secretory substance, the colour change, the development of the accessory glands and the acceleration of maturation which results from wounding.
