Abstract: The ovicidal activities of extracts from 35 species of plants (including Coronilla varia) against Mythimna separata were measured by immersion methods. The acetone extract from Levisticum officinale seeds, chloroform extract from Cnidium monnieri seeds, methanol, petroleum ether and ethyl acetate extracts from Ricinus communis seeds, methanol, ethanol, acetone and ethyl acetate extracts from C. varia roots all had strong ovicidal activities against M. separata. Corrected non-hatching ratios of eggs were 100% after 5 days treatment. Extracts of 75% methanol, and petroleum ether from L. officinale roots and of methanol and petroleum ether extracts from L. officinale seeds had strong ovicidal activities with corrected non-hatching ratios of eggs of 39.65%, 35.31%, 55.99%, 34.51% respectively. Petroleum ether extracts from C. varia roots, Datura stramonium seeds and Abutilon theophrasti seeds had some ovicidal activities - corrected non-hatching ratios of eggs were 11.45%, 11.79% and 10.60% respectively. Other extracts had no ovicidal activity. Four species of plants (C. varia, L. officinale, C. monnieri and R. communis) with effective ovicidal activities are worth further research and development.
