Abstract

A comprehensive knowledge of the nutritional ecology of insects is a requirement to understand their biology, behavior, and impact in natural ecosystems and agro-ecosystems. Although, major insect nutritional requirements for growth and reproduction are known for years, only a few dozen insects have been studied to learn their nutritional requirements. Extraordinary nutritional requirements were found in a few insects from even these few studies. It is important to understand comparative nutritional requirements in order to study insects. Nutritional ecology is a useful way to synthesize research on both the basic and applied aspects of insect behavior, and it allows us to achieve a better understanding of the evolution of different lifestyles. In this review, emphasis will be placed on insect nutritional ecology, requirements for specific nutrients, phagostimulants, and feeding deterrents.
