中文摘要:用有效成分为1000?μg/L的氟胺氰菊酯药液对雅氏瓦螨Varroa jacobsoni Oudemans敏感个体的腹部表皮进行穿透性测定,结果表明:药液无法通过表皮起毒杀作用。通过添加酶抑制剂多功能氧化酶(PBO)和酯酶(DEF)的增效测定,结果显示:PBO在抗性和敏感螨中分别增加毒效为3.27和
英文摘要:Mechanisms of fluvalinate resistance in the mite Varroa jacobsoni Oudemans, a parasite of honeybees, were tested.PBO and DEF had significant synergism to fluvalinate in the resistant and susceptible mites, and the synergism ratio was 3.23 and 1.67
