Akinneye and Afolabi, 2014, Toxicity and Fumigant Effect Of Powder and Oil Extracts of Cleisthopholis Patens (Benth) against Larvae and Adults Anopheles Mosquito, Journal of Mosquito Research, Vol.4, No.11, 1-6 (doi: 10.5376/jmr.2014.04.0011)

The ethanolic and aqueous extracts of the stem-bark of Cleisthopholis patens (Benth) were tested against the larvae and adults of Anopheles gambiae at varying concentrations (1g, 2g, 3g, 4g, 5g for powder, 1.0ml, 1.5ml, 2.0ml, 2.5ml, 3.0ml for oil extract and 0.1ml, 2.0ml, 3.0ml, 4.0ml, 5.0ml for aqueous extract). The ethanolic oil extract of C. patens had significant effect on larvae and adult of An. gambiae with percentage mortality range of 83-100% within 90mins of exposure periods. The aqueous extract of C. patens was relatively ineffective against the larvae of An. gambiae at all levels of concentrations while the fumigant effect of the powder was slightly effective against adult An. gambiae which achieved 23.30 - 36.70% mortality of the insect. The results obtained showed significant difference when the value of ethanolic extract, the aqueous extract and the powder form were compared (p<0.05). This shows that the plant oil (ethanolic extract) of C. patens is highly toxic to the larvae and adults of An. gambiae which resulted in the mortality effects.
