- Abstract
In the present investigation, larvicidal potential of hexane, choloroform, ethyl acetate, acetone, and methanol extracts of seven aromatic plants, viz., Blumea mollis, Chloroxylon swietenia, Clausena anisata, Feronia limnonia, Lantana camera, Plectranthus amboinicus, and Tagetes erecta were screened against Culex quinquefasciatus, Aedes aegypti, and Anopheles stephensi. The larval mortality was observed after 12 and 24 h of exposure period. The results revealed that all the extracts showed varied levels of larvicidal activity against the mosquito species tested. However, the ethyl acetate extract of Chloroxylon swietenia showed the remarkable larvicidal activity against C. quinquefasciatus, Ae. aegypti, and An. stephensi. After 12 h of exposure period, the larvicidal activity was LC = 194.22 and LC = 458.83 ppm ( C. quinquefasciatus), LC = 173.04 and LC = 442.73 ppm ( Ae. aegypti), and LC = 167.28 and LC = 433.07 ppm ( An. stephensi), and the larvicidal activity after 24-h exposure period was LC = 94.12 and LC = 249.83 ppm ( C. quinquefasciatus), LC = 80.58 and LC = 200.96 ppm ( Ae. aegypti), and LC = 76.24 and LC = 194.51 ppm ( An. stephensi). The larvicidal potential of other plant extracts were in order of ethyl acetate extract of Clausena anisata > methanol extract of P. amboinicus > acetone extract of F. limonia > methanol extract of T. erecta > methanol extract of B. mollis > and methanol extract of L. camera. The results of the present study offer a possible way for further investigations to find out the active molecule responsible for the activity.
