== Occurrence == Azadirachtin is found in the neem tree, Azadirachta indica, from which its name is derived, as well as Azadirachta excelsa. It is found in all parts of the tree but the highest concentration is in the seeds (0.2 to 0.8 percent by weight). It was first isolated pure in 1968 following the antifeedant activity towards the desert locust (Schistocerca gregaria), but its chemical structure was finally established later in the 1980s.
