    摘要:

    用杀虫剂联合作用方法优选山鱼藤酮混氰戊菊酯(4:1)具明显增效作用,对5龄菜粉蝶幼虫共毒系数为342.2(触杀),449.8(胃毒),对菜蚜LC501.23mg/L。该混剂对菜粉蝶幼虫有明显拒食和抑制生长发育作用,AFC50为0.7mg/L;用18mg/L混剂处理幼虫,发育抑制率为84.4%,田间试验表明,鱼藤混剂对多种害虫有高效,30mg/L的混剂的对菜粉蝶幼虫的防效相当于50mg/L的氰戊菊酯

    Abstract:

    Results of experiment showed that an admixture,mainly consisting of rotenoneand fenvalerate(4:1)gave strong contact,stomach poison and antifeedant effectand the inhibitory effect on the growth and development of Pieris rapae L.,and the co-toxicity coeffcients for contact and stomach poison were 342.2 and449.8 respectively.The admixture was used to spray in 30mg/L in pot and fieldtrials,and it gave the same control efficiency to Pieris rapae as 50mg/L offenvalerate giving and was more effective than that of 75 mg/L of rotenonegiving alon.
