Larvicidal activity of extracts of Dacryodes edulis (G. Don) H. J Lam on Aedes vittatus Bigot and Culex quinquefasciatus Say (Diptera: Culicidae)

Author(s): Halima T Akande-Grillo and Humphrey C Nzelibe
Abstract: Crude extracts of Dacryodes edulis seed and leaf were tested on Aedes vittatus and Culex quinquefasciatus late third and early fourth instar larvae. The ethanol extract of the seed gave mortality of 70.6% against the larvae of Aedes vittatus at 48 hours while the ethanol and hexane extract of the seed gave values of 74.6% against Culex quinquefasciatus. The hexane extract of the leaf produced the highest mortality at 48 hours with 70.6% against Aedes vittatus while the ethanol and hexane extracts of the leaf gave significant mortality of 82.67 and 93.3% respectively against Culex quinquefasciatus. LC50 values of the ethanol extract of the seed was 150.54 and 110.18ppm at 48 hours against Aedes vittatus and Culex quinquefasciatus respectively and the hexane extract of the leaf gave 1177 and 508.28ppm against Aedes vittatus and Culex quinquefasciatus also at 48 hours.
