Abstract

The insecticidal property of Parthenium hysterosphorous and vitex nigundi leaf extract in acetone’ against the rice weevil were very effective to control the pest Different concentration, dose were checked and the result showed that high doses or the extract of Parthenium and vitex were significantly more toxic to Sitophilus oryzae compared to lower dose.

 The probit analysis of data demonstrated mortality rate for acetone extract was mortality % of Parthenium leaf extract in acetone 5%,10%, 15% = 25%, 40%, 60% mortality % of vitex left extract in acetone 5%, 10%, 15 %= 15%, 35% 65%, Mortality % of mixture of Parthmium and vitex leaf extract in acetone =5% 10%, 15%, 30%, 40%, 80%, respectively from10 days. Hence we concluded that leaf extract of Parthenium hysterosphorous and vitex nigundi served as a potential insecticide used against (Rice weevil).

Keywords: Parthenium hysterosphorous, vitex nigundi, rice weevil, stored grain mortality insecticide
