Abstract: Control of vector mosquitoes naturally by using plants is very crucial for the prevention of the environmental toxicity that caused by insecticides. Hence, present work was focussed to evaluate the toxic nature of leaves extracts of Manihot esculenta (Cassava) against larvae and pupae of denuge transmitting vector Aedes aegypti. The fourth instars larvae of A. aegypti were used for larvicidal activity and kept a plastic container with 249 ml of distilled water and 1ml of known concentration of plant extracts and incubated for 48 hours. The mortality rate of larvae was observed frequently and recorded. Pupae of A. aegypti were put in a plastic container with 249 ml of distilled water and 1ml of desired concentration of plant extracts and incubated for 48 hours. The pupicidal activity of plant extracts was observed frequently and recorded. Different extracts of Manihot esculenta (Cassava) showed potential toxic to the larvae and pupae of the denuge transmitting vector Aedes aegypti. It was due to the presences of phytocompouds such as tannis, saponnin etc. Thus the medicinal plant Manihot esculenta (Cassava) was might be useful for control of mosquitoes after the details experiments.
