Larvicidal Activity of Neolamarckia cadamba Against the Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus

Larvicidal Activity of Neolamarckia cadamba Against the Anopheles stephensi, Aedes aegypti and... The excessive use of conventional insecticides to Culicidae leads to the emergence of mosquitoe resistant, adverse environmental and human effects. Therefore, the present study was carried out to explore the larvicidal efficacy of petroleum ether, chloroform, ethyl acetate and methanol extracts of roots, leaves, and bark of Neolamarckia cadamba against the early 4th instar larvae of Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus at concentrations ranging from 12.5 to 200 ppm under laboratory conditions. The root extracts showed the highest larvicidal potential than the leaf and bark extracts. After 24 h of exposure period, the highest larvicidal activities were observed in the methanol extract of roots with LC50 value of 43.29 and LC90 value of 202.85 ppm against An. stephensi; LC50 value of 70.82 and LC90 value of 253.73 ppm against Ae. Aegypti and LC50 value of 99.51 and LC90 value of 311.02 ppm against the Cx. Quinquefasciatus, respectively. Thus, the plant extracts of N. cadamba showed considerable mosquito larvicidal activities and can be considered for further investigation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Proceedings of the Zoological Society Springer Journals

Abstract

The excessive use of conventional insecticides to Culicidae leads to the emergence of mosquitoe resistant, adverse environmental and human effects. Therefore, the present study was carried out to explore the larvicidal efficacy of petroleum ether, chloroform, ethyl acetate and methanol extracts of roots, leaves, and bark of Neolamarckia cadamba against the early 4th instar larvae of Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus at concentrations ranging from 12.5 to 200 ppm under laboratory conditions. The root extracts showed the highest larvicidal potential than the leaf and bark extracts. After 24 h of exposure period, the highest larvicidal activities were observed in the methanol extract of roots with LC50 value of 43.29 and LC90 value of 202.85 ppm against An. stephensi; LC50 value of 70.82 and LC90 value of 253.73 ppm against Ae. Aegypti and LC50 value of 99.51 and LC90 value of 311.02 ppm against the Cx. Quinquefasciatus, respectively. Thus, the plant extracts of N. cadamba showed considerable mosquito larvicidal activities and can be considered for further investigation.
