[Objective] The main aim was to screen insecticidal plants in southwest of China. [Method] The insecticidal activities of 36 species plants methanol extracts against Brevicoryne brassicae, including Huperzia serrata, Ficus tsiangii, Ficus sarmentosa var. henryi and so on, were assayed. [Result]The corrected mortality rates of 3 species plants methanol extracts with 5 g/L concentration against B. brassicae, including F. tsiangii, F. sarmentosa var. henryi, Myrsine stolonifera, were over 60% at 12 h and 24 h after treatment. The toxicity of 3 species plants methanol extracts against B. brassicae was also studied and LC_(50) values of them were 1.26, 1.48 and 2.38 g/L, respectively. [Conclusion] The insecticidal active ingredients of 3 species plants would be worth studying.
