Objective:To evaluate the potential efficacy of seed extracts of Annona squamosa and Annona muricata used as natural insecticides to control adult and larvae of the vectors Aedes albopictus and Culex quinquefasciatus under laboratory ***:Aqueous and oil extracts of the two plants were prepared from dried *** identifications of the chemical components of each seed extracts were performed using microreactional and GCP *** and adults of Aedes albopictus and Culex quinquefasciatus were collected from the breeding sites in coastal and highlands regions of *** standardized tests of susceptibility for larvae and imaginal stage of mosquitoes were realized to determine mortality and LC_(50) of ***:Chemical identifications showed that these extracts contain alkaloids and flavonoids compounds that probably confer their biological insecticidal *** analysis showed also the presence of various fatty *** adult mosquitoes,significant insecticidal effects were observed with both aqueous and oil extracts of the two plant seeds compared to mortality induced by deltamethrin,an insecticide used as *** of Annona muricata induced high mortality rate to both species of mosquito compared to extracts of Annona squamosa at all concentrations *** LC_(50) of seed extracts ranged from 1%to 5%for adults and 0.5%to 1%for ***:The seed extracts of these two plants may be used as mosquito controlling agents and offer a new approach to a less costly,practical and environmentally friendly control of vector borne diseases.
