中文摘要：

采用玻片粘胶浸渍法测定＂绿满园＂水剂对柑桔红蜘蛛Panonychus citri的生物活性,同时采用浸渍法测定＂绿满园＂水剂对三突花蛛、斜纹猫蛛和拟环纹豹蛛3种蜘蛛的毒力.结果表明,16%＂绿满园＂水剂18.75倍稀释液对红蜘蛛毒性最强,处理72h后红蜘蛛死亡率可达99.0%.受药48h后,＂绿满园＂对红蜘蛛的毒力回归方程为y=5.175 6＋1.183 8x,致死中浓度LC50为0.710 6mg/mL.16%＂绿满园＂水剂对三突花蛛和斜纹猫蛛无毒性,但对拟环纹豹蛛有较强的毒性,75倍稀释液处理过的拟环玟豹蛛24h后死亡率可达70%.

英文摘要：

The slides viscose immersion method was taken to determine the toxicity of ＂Lümanyuan＂ to Panonychus citri,in the meanwhile,investigated the influence of ＂Lvmanyuan＂ on three kinds of spiders,Ebrechtella tricuspidata,Oxyopes sertatus and Pardosa pseudoannulata.The results showed that the toxicity of 16% ＂Lümanyuan＂ to P.citri was the strongest when diluted by 18.75 times,and the mortality could reach 99.0% after 72 h treated by the pesticide.48 h after treatment,the linear regression equation of ＂Lümanyuan＂ to P.citri was y=5.175 6＋1.183 8x,LC50=0.710 6 mg/mL.＂Lümanyuan＂ was non-toxic to E.tricuspidata and O.sertatus,but it had a strong toxicity to P.pseudoannulata,actually.The mortality of P.pseudoannulata can reach 70% after 24 h treated by the 75 times diluted pesticide.
