Azadirachta indica : a source of insect feeding inhibitors and growth regulators /

Nontoxic, environmentally sound methods of pest control are of prime importance.For this reason neem tree components have been suggested as insect feeding inhibitors and growth regulators for 16 years.The activity of neem components upon Acari, Insecta, and Nematoda has been compiled.Some of these components, such as meliantriol, azadirachtin, and salannin, have been obtained in pure form.The structures of these triterpenoids along with the structures of other untested triterpenoids from neem have been incorporated into this review.All of these structures can serve as model compounds for the synthesis of commercially feasible insect feeding inhibitors and growth regulators to control larval and adult forms of stored-grain pests, termites, grass¬ hoppers, locusts, and nematodes.
