Mosquitoes are responsible for the intolerable biting nuisance and the transmission of a large number of diseases, such as malaria, yellow fever, dengue, filariasis, chikungunya. Many studies on plant extracts against mosquito larvae have been conducted around the world. The present study were conducted in order to determine the phytochemical analysis, larval and pupal toxicity, ovicidal activity of Malvastrum coromandelianum and Mimusops elengi methanolic leaf extract against the dengue vector, Aedes aegypti. Phytochemical analysis of M. coromandelianum methanolic leaf extract revealed the presence of alkaloids, flavonoids, phenols, tannins, proteins, carbohydrates, steroids, triterpenoids and M. elengi leaf extract contains alkaloids, flavonoids, phenols, carbohydrates, steroids, triterpenoids and saponins. GC/MS analysis identified at least 25 bioactive compounds in the M. coromandelianum methanolic leaf extract and 10 bioactive compounds in M. elengi methanolic leaf extract. In mosquitocidal bio-assay, LC50 of M. coromandelianum leaf methanol extract against Aedes aegypti larvae and pupae were 378.59 ppm (larva I), 404.42 ppm (II), 415.35 ppm (III), 486.01 ppm (IV), and 509.59 ppm (pupa). LC50 of M. elengi were 345.31 ppm (I), 389.62 ppm (II), 417.41 ppm (III), 467.33 ppm (IV), and 499.17 ppm (pupa). In ovicidal assay, egg hatchability was reduced by 100% after treatment with 400 ppm of M. coromandelianum and M. elengi. Overall, our results highlighted that M. coromandelianum and M. elengi could be useful candidates to develop bio-formulated mosquitocidal effective against dengue vector, Ae. Aegypti.
