| Abstract: | Reported the insecticidal activity of ＂Chachongqing＂,a botanical pesticide and it＇s effect on non-target organisms.At the concentration of 80 mg/mL,the extract showed significant antifeedant effect on Lipaphis erysimi,Pieris rapae,Plutella xylostella,and Empoasca vitis.The AFC50 after 48 h were 12.03,35.37,15.05 and 55.07 mg/mL.The water extracts showed larvicidal activity against 2nd larvae of Ectropis obliqua.Under the concentration of 200 mg/mL,the larval mortality after 96 h was 77.78%（LC50=71.4 mg/mL）.＂Chachongqing＂ also had strong growth inhibitors to Pieris rapae and Plutella xylostella,but the effect of growth inhibitory to Pieris rapae（75%） was better than to Plutella xylostella（52.78%）.Immersion method was also used to test the toxicity of ＂Chachongqing＂ on two natural enemies of insects： two species of spider（Pardosa pseudoannulata,Pirata subpiraticus） and a chrysopa（Chrysopa septempunctata）.The results showed that the ＂Chachongqing＂ was safe to them. |
