Inula racemosa, Tagetes minuta, Callosobruchus chinensis, Chrysanthemum cinerariaefolium
Experiments were conducted in Bio-pesticide and herbal extract Laboratory, Department of Zoology, D.B.S. College, Kanpur. In the present investigations, repellent bioefficacy of ten indigenous asteraceous plant aquash extracts viz; Chrysanthemum cinerariaefolium (trev.) Vis., Chromolaena odorata Linn. Cichorium intybus (Chicory), Inula racemosa Hook. f, Reichardia tingitana Linn. Roth, Rhaponticum acaule (L.) DC., Scorzonera undulata Vahl., Spilanthes paniculata Well ex DC, Mantisalca duriaeri (Spach) Birq. Et Cavill. and Tagetes minuta L. were tested against early emerged adults of Callosobruchus chinensis under laboratory conditions. The aquash extract of C.cinerariaefolium, I.racemosa (roots), M.duriaeri, R.tingitana, R.acaule, T.minuta (flowers), C.intybus, S.undulate (aerial parts) and C.odorata, S.paniculatai (leaves) were tested to find out their repellent effect against the early emerged adults of C.chinensis. The Cichorium intybus extract proved to be the best repellent against emerging adults beetle C.chinensis. The other nine plant extracts have been shown in descending order as Inula racemosa > Chrysanthemum cinerariaefolium > Tagetes minuta > Mantisalca duriaeri > Scorzonera undulata > Reichardia tingitana > Spilanthes paniculata, respectively. The relative EC values of the above extracts are in descending order, 5.5529 > 50 5.2444 > 3.0353 > 2.4205 > 1.4842 > 1.3760 > 1.1668 > 1.0000 times as repellents, whereas Spilanthes paniculata is taken as a unit.
