Efficacy of different concentration of azadirachtin isolated from fruits of Melia azedarach was investigated on the different stages of Anopheles pulcherrimus under lab. condition. Results showed that there was non-significant reduction in eggs hatching rate. There were high significant in larval mortalities which were depending on concentration. Different larval deformities were found. Second instars larvae were more sensitive then fourth larva instar , LC50 and LC90 for the second instars larvae were 35.99 and 67.99 ppm respectively and for the fourth instars larvae it was 63.09 and 139.8 respectively, significant prolongation in larval development period.
