ABSTRACT
<p><b>OBJECTIVE</b>To study the bioactivities of the extracts from Pinellia ternata against Plutella xylostella.</p><p><b>METHOD</b>The active material in P. ternata was Soxhlet extracted with petroleum ether, ethyl acetate, ethanol successively. The bioactivities of the extracts were determined.</p><p><b>RESULT</b>Results indicated that all extracts using three solvents showed inhibition of oviposition and ovicidal action activities, but the activity of ethanol extract was the strongest. The higher concentration, the more obviously the effect on the pest was. 24 h after treatment with 100 g x L(-1) ethanol extract in no-choice tests and choice tests, the deterrent rates were 85.13%, 73.38%, respectively. Furthermore, treatment with 100 g x L(-1) ethanol extract after 5 d could effectively reduced the percentage of eggs incubation, ovicidal rate could reach 62.40%.</p><p><b>CONCLUSION</b>These results suggest that extracts of P. ternata could be used to control pest.</p>
