摘要
采用毛细管点滴法 ,测定了浙江慈溪水稻二化螟对 4类 9种杀虫剂的抗性和敏感性水平。结果表明 ,该地的二化螟对杀虫双、杀虫单、杀虫安、甲胺磷 4种杀虫剂均已产生高水平抗性 ,对杀螟硫磷已产生中抗 ,对甲基对硫磷、三唑磷、氰戊菊酯则仍保持敏感水平 ,同时发现二化螟对氟虫腈极为敏感 ,对 6龄幼虫的LD50 仅 0 .
Resistance level of rice stem borer ( Chilo suppressalis Walker) to several conventional insecticides was tested with topical application in Cixi,Zhejiang Province.Results showed high level of resistance appeared to dimhypo and other two derivatives,methamidophos;moderate level of resistance to fenitrothion;but parathion methyl,triazophos,fenvalerate remained susceptible.The borer was discovered to be extremely susceptible to fipronil with LD 50 to 6 instar larvae being 0.3833 μg/g.
