Four bioagents, viz., Coccinella septempunctata L., Menochilus sexmaculatus (F.), Chrysoperla carnea (Stephens) and Verticillium lecanii (Zimmerman), were evaluated against mustard aphid, Lipaphis erysimi (Kaltenbach), on single plants covered with muslin cloth in the field at National Research Centre on Rapeseed-Mustard, Sewar, Bharatpur (Rajasthan) during 2005-06 and 2006-07. C. septempunctata @ two adults/plant was found to be the most effective, reducing 96.19% of the aphid population in 10 days followed by C. septempunctata @ two larvae per plant (93.42%), V. lecanii @ 108 spores-ml (84.90%), M. sexmaculatus @ two adults (84.62%) and C. carnea @ four larvae-plant (82.98%). C. septempunctata @ one adult per plant reduced the aphid population by 77.49% and M. sexmaculatus by 69.08%.
