Abstract:
Screening test was done for antifeedant activity of some indigenous natural botanical extractives as discovery of new biorational agents for insect-pest management. The test insect leaf webber, Eucosma critica Meyrick (Lepidoptera: Eucosmidae) is a serious pest, causing enormous qualitative and quantitative losses to various leguminous crops and vegetables. The eleven edible and non-edible essential oil-containing plants growing wildly in India namely: Ageratum conyzaides Linn., Argemone maxicana Linn., Arachis hypogea Linn., Azadirachta indica A. juss., Brassica juncea Linn., Chenopodium ambrosioides Linn., Mentha arvensis Linn., Mentha longifolia Linn., Ocimum basilicum Linn., Pongamia glabra Vent. Ricinus communis Linn and Endosulphan were tested for their antifeedant biopotency against larvae of. Eucosma critica and one synthetic insecticide also used in the present investigation. Based on relative EC50 values Chenopodium ambrosioides seeds extract showed highest protectivity (EC50=0.013) to the larvae of Eucosma critica followed by Argemone maxicana Linn. (EC50=0.017), Brassica juncea Linn. (EC50=0.037), Azadirachta indica A. Juss. (EC50=0.197), Ageratum conyzaides Linn. (EC50 = 0.209), Pongamia glabra Vent (EC50 = 0.279), Arachis hypogea Linn. (EC50 = 0.317), Ocimum basilicum Linn. (EC50=0.339), Ricinus communis Linn. (EC50=0.413), Mentha arvensis Linn. (EC50=0.447), Mentha longifolia Linn (EC50=0.532), times repellent than Endosulfan (EC50=0.516), respectively. Thus, Chenopodium ambrosioides, Argemone maxicana and Azadirachta indica seed oils showed a sound commercial herbal antifeedant alternatives to the more persistence synthetic pesticides for managing the against larvae of Eucosma critica Meyrick
