Research into the insecticidal effects of azadirachtin, a limonoid from the Indian Neem tree,
Azadirachta indica, has been ongoing for some 30 years. Its strong antifeedant, insect …

The word “limonoids” originated from the bitterness of lemon or other citrus fruit. Structurally,
limonoids are formed by loss of four terminal carbons of the side chain in the apotirucallane …

The neem tree has long been recognized for its unique properties both against insects and
in improving human health. It is grown in most tropical and sub-tropical areas of the world for …

After more than 70 years of chemical pesticide use, modern agriculture is increasingly using
biological control products. Resistances to conventional insecticides are wide spread, while …

Limonoids are the most distinctive secondary metabolites of the plant order Rutales. Recent
work has established a wide range of biological activities for these compounds, including …

Azadirachtin is the most effective compound of the neem tree, Azadirachta indica A. Juss,
