Larvicidal activity of crude petroleum ether (PE), ethyl acetate (EtOAc) and methanol
(MeOH) extracts of leaves and stem barks of Sterculiaquinqueloba (Garcke) K. Schum
were testedagainst the late 3
instar larvae of Anopheles gambiae, Aedesaegypti and
Culexquinquefasciatusat 5 different concentrations50 – 800µg/ml. The larval mortality was
observed after 24h, 48h and 72h of exposure. At 24h of exposure all extracts showed
moderate larvicidal effects, except for methanolic extracts which showed very week
effect at LC
50
rd
>750µg/ml.The highest larvicidal activityrecorded for leaf extracts against
each species used were LC
50
27.61µg/ml(EtOAc extracts), LC
50
43.9µg/ml(PE extracts)
and LC
50
68.2µg/ml(EtOAc extracts) for A. gambiae, C. quinquefasciatus and A. aegypti
respectively. Only EtOAc extract of stem against A. gambiae gave LC
50
range between 50 -
100µg/ml. Generally leaf extracts showed higher activity than stem extract. This is an
ideal eco-friendly approach aid for the control of mosquito species A. gambiae, A. aegypti
and C. quinquefasciatus. |
