Neem extracts and pure azadirachtin influence the behaviour and physiology of large number of insects. These compounds affect the sensory receptors, thereby inhibit food intake. This anti-feedant property is exploited by using neem extracts and azadirachtin for plant protection. The gut motility and movement of food in the digestive tube are regulated by azadirachtin.
Azadirachtin and neem extracts regulate the reproductive functions of insects through their endocrine system. Morphogenesis, ovarian development, fecundity, egg viability and moulting are adversely affected by azadirachtin. Radioimmunoassays show that the ecdysteroid level falls drastically on azadirachtin treatment. Juvenile hormone synthesis also is inhibited in
