Abstract
The antifeedant and
larvicidal activities of Madhuca longifolia leaf (ethyl acetate) extract
fractions were evaluated at different concentrations against larvae of Spodoptera
litura. Antifeedant activity values
for fraction I at concentrations of 500ppm, 250ppm, 125ppm, and 62.5ppm were
41.10%, 30.54%, 23.92% and 14.14%; for fraction II is 55.47%, 32.46%, 23.64%,
and 14.67%; for fraction III is 78.23%, 48.54%, 33.28%, and 21.04%; for
fraction IV is 56.10%, 38.69%, 25.97%, and 16.27%; for fraction V is 47.78%,
30.74%, 21.27%, and 14.12% respectively. The larvicidal activity of Madhuca
longifolia fractions against larvae of Spodoptera litura were values
recorded in fraction I at concentrations 500ppm, 250ppm, 125ppm, and 62.5ppm
were 36.52%, 23.73%, 17.56%, 13.17%, for fraction II is 50.68%, 31.37%, 20.44%,
15.54%, for fraction III is 71.13%, 51.57%, 39.71%, 23.54%; for fraction IV is
51.55%, 37.41%, 23.14%, 14.67%; for fraction V is 31.48%, 26.51%, 19.21%,
11.12%. The antifeedant and larvicidal activities for maximum values recorded
in Madhuca longifolia leaf (ethyl acetate) extract fraction III against
larvae of Spodoptera litura respectively.
