Mosquitoes constitute a serious Public Health menace, resulting in millions of death worldwide each year. Emergence of insecticide resistant strains of the mosquitoes poses a serious threat and hence calls for alternative control measures. This study assessed the larvicidal efficacy of the methanolic leaf extract of Calotropis procera against the post emerged Adult of Culex quinquefasciatus after ten generations. Adulticidal activities of the leaf, of the plant was therefore studied on laboratory reared Adult of Culex quinquefasciatus. The result of longevity of post emerged adult Culex quinquefasciatus after ten (10) generations shows a higher longevity value recorded in females compared to the males and in both the males and females, decrease in longevity value was recorded from the first to the tenth generation. The results show a significant difference in the mean longevity values between the male and the female at P<0.05 level of significance and also between the test group and the control at P<0.05 with the control having the highest longevity values. The results of this research therefore under-scores the efficacy of the plant and further suggest the use of methanolic leaf extracts of Calotropis procera as an eco-friendly alternative in the control of filarial worm vector as Adulticide.
