Abstract

Acetogenins isolated from the seeds of Annona squamosa shows a number of biological activities. In the present study acetogenins have shown larvicidal and growth regulating activities against Anopheles stephensi at concentrations of 1 to 2 mg. Fall in population as a result of mortality of larvae, pupae and adults ranged from 79-86% as compared to control. The average larval, pupal and developmental periods increase with the increase in the concentration of acetogenins. Further studies and field trials are needed to recommend the acetogenins of A. squamosa for mosquito control and to establish the cause of mortality.
