When the tree reaches maturity, it can produce until 50Kg of fruits what is equivalent to 30Kg of seeds. These ones constitute the main source of components with some insecticidal properties as the azadirachtin. However, the quantity of azadirachtin contained in the seeds considerably changes according to the climatic conditions, the soil conditions and the genotype of the tree (Ermel 1986 ; Singh 1986).
