Aphidicidal compatibility of certain ecofriendly asteraceous biorational extractives against okra aphid, Aphis gossypii Glover (Hemiptera: Aphididae) under field conditions
Author(s): Anju Bharti and BS Chandel
Abstract: Plants products are increasingly used in the management of insect pest. They are superior to chemical pesticides because of their biodegradable nature and lesser environmental toxicity. Experiments were conducted in the Departmental Research Laboratory and experimental field of farmer affiliated to Department of Zoology, D.B.S. College, Kanpur, U.P., India. In the present investigation, indigenous naturally occurring ten biorational asteraceous plant extractives have been used for their aphidicidal bioefficacy against okra aphid, Aphis gossypii Glover (Hemiptera: Aphididae) on okra; Abelmoschus esculentus Linn. Moench (Malvaceae). Three concentrations viz. 0.5 per cent, 1.0 per cent and 2.0 per cent of each plant extract were selected and tested by dry film technique against nymphs and adults of Aphis gossypii on okra field. The results showed that maximum mean mortality was observed in extract of Chromolaena odorata (75.77%) against nymphs and adults of Aphis gossypii which is followed by Acmella paniculata (74.25%) > Tagetes minutia (69.32%) > Chrysanthemum cinerariifolium (68.69%) > Ropanticum acaule (66.80%) > Scorzonera undulate (66.46%) > Mantisalca duriaeri (66.20%) > Reichardia tingitana (53.84%) > Inula racemosa (53.55%) > Cichorium intybus (40.37%), respectively. The extracts of C. odorata differs from significant remaining once except Acmella paniculata and T. minuta, which does not differ significantly to one another. Cichorium intybus proved least toxic giving only 40.37 per cent mortality of the nymphs and adults of Aphis gossypii. This paper was aimed to use the biorational asteracious extractives for the ecofriendly management of okra aphid infesting on bhindi, Abelmoschus esculentus Linn.
