Brevipalpus yothersi mite is the main vector of Citrus leprosis virus (CiLV), the causal agent of citrus leprosis disease. The acaricide spirodiclofen has been widely used to control this mite. However, failures in control using spirodiclofen have been frequently reported by citrus growers. In this study, we estimated the diagnostic concentration to monitor the resistance to spirodiclofen of B. yothersi populations collected in nine citrus groves in Brazil. We then selected the B. yothersi population that showed lowest mortality with the estimated diagnostic concentration of spirodiclofen to characterize the frequency of resistant individuals, as well as demographic and life table parameters.

来自巴西柑橘园的 Brevipalpus yothersi（Acari：Tenuipalpidae）对螺环氯芬的抗性：检测、监测和种群表现

Brevipalpus yothersi mite 是柑橘麻风病毒 (CiLV) 的主要载体，柑橘麻风病毒是柑橘麻风病的病原体。杀螨剂螺螨酯已被广泛用于防治这种螨。然而，柑橘种植者经常报告使用螺环氯芬控制失败。在这项研究中，我们估计了诊断浓度，以监测巴西九个柑橘园中收集的约瑟斯双歧杆菌种群对螺环菌酯的抗性。然后，我们选择了死亡率最低的B. yothersi种群，并用估计的螺菌洛芬诊断浓度来表征耐药个体的频率，以及人口统计学和生命表参数。
