| Abstract: | The bioactivity of the acetone extracts of 53 species wild plants collected from Xiaolongshan forest area were tested with Pieris rapae in the laboratory.Results showed that antifeedant rate to the test insects is more than 50% of them were 12 species,of which the antifeedant rate of 84.5% of Macleaya microcarpa(Maxim.) Fedde was highest,antifeedant rate also higher were Urtioca cannabina L.,Melia toosendan Sieb.et Zucc.,Celastrus orbiculatus Thunb.,Rheum palmatum L.,Melia azedarach L.,Nicatiana tabacum L.,Pulsatilla chinensis(Bge.) Regel,Datura stramonium L.,Urtiac laetevirens Maxim.,Euphorbia sieboldiana Morr.et Decne,Cicuta virosa L.,antifeedant rates were 73.7%,71.6%,64.5%,60.2%,(58.2%,)(56.1%,)(55.9%,)53.3%,52.8%,51.9%,51.2%. |
