Abstract: In order to evaluate the function of M. micrantha extracts on pest control, oral toxicity and antifeedant activity of M. micrantha extracts from 3 solvents on B. longissima were studied in laboratory. The results indicated that all the three extracts showed oral toxicity on B. longissima, and no significant difference was detected with overlaps among 95% confidence intervals of LC50. There was significant difference between N-butanol extract and Cyclohexane extract in antifeedent activity. M. micrantha extracts had potential on B. longissima control. The results may provide reference for IPM of B. longissima.
