Abstract: The present manuscript covers the preliminary screening of feeding toxicity of certain naturally occurring crude extract against chickpea bruchid, Callosobruchus chinensis Linn. (Coleoptera: Bruchidae) infesting on chickpea, Cicer arietinum L. ver. K 850 seeds. The selected plant materials viz; aerial parts of Vitex negundo Linn., Withania somnifera Dun., Swertia chirayita Roxb., Tabernamontana devaricata Linn., ripe fruites of Jatropha curcus Linn., Nyctanthes arbortristis Linn., unripe fruits of Lantana camara Linn., Momordica charantia Linn., rhizomes of Zingiber officinale Rosc. and Saussurea lappa C.B. Clarke were used for their insecticidal effectiveness against early emerging adults of pulse beetle, C. chinensis Linn. in laboratory trials. The crude extract of each plant was selected and tested by dry film technique for early emerging beetles of C. chinensis on pulse grain. The data depicted from the results that among selected bioactive crude plant extracts maximum mean mortality was observed in L. camara (77.0) followed by V. negundo (75.40) and W. somnifera (71.14), respectively. It can be concluded on the basis of result obtained that these plant could be use as biorational insecticide in their soxhlet extract or their biochemical farm in future for the protection of grains under storage conditions.
