【摘要】 狄斯瓦螨是全世界蜜蜂最严重的寄生虫,目前,它对主要防治药物——拟除虫菊酯类的氟胺氰菊酯已产生明显抗性,严重影响其防治效果。近年来神经生理学研究结果证实:电压门控的钠离子通道是拟除虫菊酯作用的靶变点。钠通道结构的改变,是拟除虫菊酯类杀虫剂毒理的主要基础,也是产生抗药性的基础。本文介绍了近年来国内外研究电压门控钠离子通道、拟除虫菊酯对钠通道的作用、钠通道与拟除虫菊酯的抗性和狄斯瓦螨(V.destructor)对氟胺氰菊酯抗性机理研究的新进展。更多还原

【Abstract】 Varroa (Varroa destructor)is an ectoparasite of honeybee and Distributed worldwide. The beekeeping industry around world has been severely impacted by the mite. Tau-fluvalinate, a kind of pyrethroids are routinely used to control this mites. Unfortunately, varroa recently developed resistance to tau-fluvalinate in the world .Genetic and biochemical studies have contributed to our understanding of pyrethroids resistance. Recent study shows that Target site ( sodium channel)insensitivity emerged as one of the most important pyrethroid resistance mechanisms in many insect specis. so this paper introduced : Voltage sensitive sodium channels; Action of pyrethroids on Voltage sensitive sodium channels; Sodium channels gene mutation underlies the mechanisms of pyrethroids resistance; Advances in research of f luvalinate resisitance in Varroa destructor.更多还原
