Mosquito larvicidal activity of Cadaba indica lam leaf extracts against the dengue vector, Aedes aegypti

Mosquitoes are associated with the transmission of malaria, dengue, chikungunya, Japanese encephalitis, filariasis and other viral diseases throughout the globe. The present study was carried out to establish the properties of leaf extract of Cadaba indica lam with different solvents Ethanolic, Hexane, Chloroform and Petroleum ether - were tested for larvicidal activity against mosquitoe such as dengue vector, Aedes aegypti. The Ethanolic, Hexane, Chloroform and Petroleum ether was moderate considerable mortality; however, the highest larval mortality was ethanolic extract observed in mosquito vector. The ethanolic extract had higher mortality with the values of LC50= 115.70, 96.09, 144.50, and 143.75 ppm and LC90= 215.46, 204.98, 233.82 and 260.86 ppm was observed. The results suggest ethanolic extract of C.indica lam have potential to be used as an good larvicidal activity an ideal eco-friendly approach for the control of dengue vector, A. aegypti as target species of vector control programs.
