An experiment was conducted to test three plant products under laboratory conditions against woolly-bear caterpillar, Pericallia ricini (F.) (Arctidae: Lepidoptera). The Sweet flag, Acorus calamus Linn. (Rhizomes), Cinnamonum aromaticum Nees. (Seeds) and nirgundi, Vitex negundo Linn. (Leaves) petroleum ether extract were tested on castor-bean, Ricinus communis. Chemical control of woolly-bear caterpillar, Pericallia ricini using insecticides of common use has done in many time leave residues that may remain viable for noticeable periods and uneconomical, hence studies have been made at the Department of Zoology, Dayanad Brijendra Swaroop Collage, C.S.J.M. University, Kanpur, Uttar Pradesh, India Concentrations 0.5,1.0 and 2.0 per cent formulations of above mentioned plant extracts. Acorus calamus Linn. Rhizomes extract showed 73.33, 83.33 and 100.00 per cent, Vitex negundo leaves extract 73.33, 76.66 and 93.33 per cent whereas Cinnamonum aromaticum gave only 16.66, 23.33 and 33.33 per cent mortality of woolly bear caterpillars of Pericallia ricini were observed after 72 hours in field trials. All the extracts were considerably superior over control.
