Abstract: In the present investigation, experiments were conducted in the Entomology Research plant product Laboratory, Department of Zoology, D.B.S. College, Kanpur, UP, India. Ten indigenous naturally occurring plants viz viz., aerial parts of Cichorium intybus (L.), Chromolaena odorata Linn., Chrysanthemum cinerariaefolium (trev.) Vis., Inula racemosa Hook. F., Mantisalca duriaeri Birq. Et Cavill., Rechardia tingitana (L.) Roth, Rhaponticum acaule (L.) DC, Scorzonera undulate Vahl, Spilanthes paniculata Well ex DC and Tagetes minuta Linn. were used for their repellent effectiveness against early emerging adults of pulse beetle, Callosobruchus chinensis (L.) (Bruchidae:Coleoptera).Under storage condition the botanicals like seed extract of Cichorium intybus gave the highest repellency to early emerging adults of pulse beetle, C. chinensis. It shows 7.41 times more repellent to C. chinensis than Acorus calamus (1.00), which is taken as unit. The result reveals that relative repellent biopotential of remaining extractives are as - > Inula racemosa (6.39) > Tagetes minuta (5.88) > Chrysanthemum cinerariaefolium (5.42) > Mantisalca duriaei (2.77) > Reichardia tingitana (1.67) > Scorzonera undulate (1.61) > Chromolaena odorata (1.61) > Chromolaena odorata (1.35) > Spilanthes paniculata (1.00), respectively.
