| Abstract: | Using 95% alcohol,the plant extracts of Podocarpus nagi,Lllicium micranthum,Ervatamia divaricata,Cornus controversa and Polygonum hydropiper were extracted.Every kind of extracts was diluted to three concentrations:1,5,and 10 times.The bioassays of contact toxicity were tested by micro-drip on Aphis citricola in laboratory.The contact toxicity of the 5 kinds of plant extracts on A.citricola were Polygonum hydropiper>Podocarpus nagi>Cornus controversa>Ervatamia divaricata>Lllicium micranthum. |
