Anti termite activity of Jatropha curcas Linn. biochemicals

Jatropha curcas oil and its toxic fraction were evaluated at different dilutions i.e., 1%,5%,10%,20% against microcerotermes beesoni, the test termite. the maximum wood protection against termites of both the treatments were obtained at their highest concentration i.e. 20%. the weight loss ranged from 18.77% to 48.80% at concentrations of 20% to 1% of jatropha curcas oil formulation. the protection afforded by toxic fraction was enhanced, with the % weight loss ranging from 10.48 to 35.19. however, all the treatments proved to be effective over the control (50.84%).
