M. IlonduE. MarksonA.A. EkelemeE. 6201266A comparative laboratory bioassay of the essential oil extracts of M. koenigii
(seed), Citrus paradisi (seed) and the leaves, stem barks and roots of
Alstonia boonei, Alternanthera repens, Eclipta prostrata and Rothmannia
longiflora and their combination were compared with ivermectin against the
third infectious microfilaria larva of Simulium yahense. Bioassay test
showed remarkable larvicidal properties for ivermectin and the plant species under
study as they could induce significant mortalities at low and varying concentrations
in the larva of S. yahense. The LC50 and LC90 values
estimated for M. koenigii, Citrus paradisi, Alstonia boonei, Alternanthera
repens, Eclipta prostrata, Rothmannia longiflora, their combination and ivermectin
are 5.75 and 13.18, 8.38 and 15.49, 3.02 and 15.49, 2.472 and 9.33, 2.87 and 12.88,
2.93 and 13.49, 2.61 and 3.16 and 2.43 and 5.37 ppm, respectively. The study revealed
that ivermectin and the combination of the plant extracts could induce 100% mortality
of the larva at a dose dependent response.]]>Ali, M.M., O.Z. Baraka, S.I. AbdelRahman, S.M. Sulaiman, J.F. Williams, M.M. Homeida and C.D.
