Various plant parts like unripe fruits of Momordica charantia Linn. (Cucurbitaceae), rhizomes of Zingiber officinalis Linn. (Zingiberaceae), leaves of Withania somnifera Dun and Solanum nigrum Linn. (Solanaceae), were taken for preparation of powder and extractions under laboratory condition. From obtained extract different concentrations (0.5, 1.0 and 2.0 percent) were prepared for experimentation against Bihar hairy caterpillar, Spilarctia obliqua Linn. (Lepidoptera: Arctiidae) and one untreated control was also done. The result from observations on mean mortality of three treatment and each treatments with three repelications were calculated. The highest mortality was recorded in Momordica charantia Linn. (72.83%) followed by Withania somnifera Dun. (64.82%) and Solanum nigrum Linn. (64.82V) whereas Z. officinalis Linn. (59.64%), and control (12.26%), respectively.
