Phytochemical constituents and larvicidal efficacy of Calopogonium mucunoides leaf and Chrysophyllum albidum seed extracts against the Aedes aegypti larvae

The larvicidal efficacy of Calopogonium mucunoides leaf and Chrysophyllum albidum seed extract against 2nd 3rd larval instars Aedes aegypti was investigated in an acute bioassay. bioassay done triplicate ten laboratory-reared larvae Ae. at four different concentrations (250, 500, 750, 1000 ppm) with a simultaneous control 24 h, 48 72 h exposure. Phytochemical screening revealed the presence alkaloids, terpenoids, tannins, saponins extracts. C. extracts varied significantly concentration exposure time (p < 0.05). Lethal (LC50 LC90) for were 2.935 7.608 ppm, 2.096 6.302 1.626 5.866 ppm (2nd instar larvae), 2.923 11.067 9.686 2.033 6.946 (3rd while had values 3.231 7.393 2.755 6.123 2.278 4.584 3.731 7.021 2.843 4.526 2.774 4.202 larvae). chloroform fraction partitioning gave 100% mortality larvae, its being more potent than extract. potential bioactive compound extant these plants could become substitute conventional insecticides synthetic pesticides ought to be further explored mosquito larvae.
