- Abstract
In the present study, pesticidal activity of lectin against different life stages of major groundnut defoliator Spodoptera litura has been studied under in vitro condition. Lectin was isolated from pulp of banana and partially purified by silica gel and mannose - sepharose 4B affinity chromatography and the total yield of affinity purified lectin was about 50 mg. Bio assay was studied against second and third instars of S. litura which reveals both the instars were susceptible to the lectin in concentration dependent manner. Distinct effect on lethal concentration 50 (LC 50), lethal time 50 (LT 50) against the larval instars, pupal, adult emergence and adult longevity was observed.
