摘要:
 为明确陕西省关中地区苹果园苹果全爪螨(Panonychus ulmi)田间种群对4种常见杀螨剂的抗药性现状，并指导该螨的田间药剂防治。采用玻片浸渍法，对采自陕西兴平、礼泉、淳化、扶风和凤翔5个地区苹果园苹果全爪螨田间种群进行毒力测定，并分析其相对抗性水平。结果表明，礼泉种群对阿维菌素和噻虫嗪LC50值最低，分别为0.041 mg·L-1和58.578 mg·L-1，凤翔种群对哒螨灵和三唑锡LC50值最低，分别为11.202 mg·L-1和96.181 mg·L-1；各田间种群对阿维菌素的相对抗性倍数为1.11~1.88倍，对哒螨灵的相对抗性倍数为1.36~3.61倍，对噻虫嗪的相对抗性倍数为1.11~3.14倍，对三唑锡的相对抗性倍数为1.84~2.43倍。总之，不同地区苹果全爪螨田间种群对药剂抗性水平不同，兴平种群对哒螨灵和凤翔种群对噻虫嗪的致死中浓度明显高于其他4个地区，田间实际防治过程中应根据各地实际情况有针对性地进行用药。
Abstract:
 The aims of this study were to investigate the resistance levels of the field populations of Panonychus ulmi (Koch) collected from the apple orchards in Guanzhong (central area of Shaanxi Province,China) to four kinds of acaricides,and to provide guidance for chemical control of P.ulmi.The slide-dip method was used to test the toxicity,the apple orchards were located in Xingping,Liquan,Chunhua,Fufeng and and Fengxiang.The P.ulmi population from Liquan showed the lowest LC50 to abamectin (0.041 mg·L-1) and thiamethoxam (58.578 mg·L-1),and the population from Fengxiang showed the lowest LC50 to pyridaben (11.202 mg·L-1) and azocyclotin (96.181 mg·L-1).The field populations of P.ulmi had different relative resistance to different acaricides,with the relative resistance ratios of 1.11-1.88 to abmectin,1.36-3.61 to pyridaben,1.11-3.14 to thiamethoxam,and 1.84-2.43 to azocyclotin.In a word,the relative resistance levels to four acaricides varied within populations of P.ulmi from different locations.Xingping population showed the highest LC50 value to pyridaben,and Fengxiang population showed the highest LC50 value to thiamethoxam.Our results suggested that the application of acaricides should be varied significantly with the populations of P.ulmi from different locations.
