Tetranychus urticae Koch is one of the most common and harmful pests in vegetable production areas. Similar to other countries, control of T. urticae is mainly based on acaricides in Turkey. However, T. urticae rapidly develops resistance and failures in chemical control have occurred frequently. The toxicity of various acaricides was investigated in ten T. urticae populations collected from vegetable crops in Turkey. In addition, populations were screened for the presence of currently known target-site resistance mutations. It was shown that resistance to bifenthrin was the most widespread, but also half of the populations were resistant to abamectin and hexythiazox. Resistance mutations in the voltage-gated sodium channel (VGSC) and chitin synthase 1 were found in various populations. Moreover, for the first time, F1538I and L1024V VGSC mutations were reported for Turkish populations. Mutations that confer resistance to abamectin, bifenazate and METI-I acaricides such as pyridaben were not detected. These results will contribute to the design of an effective resistance management program in Turkey.
土耳其真叶螨（Tetranychus urticae Koch）是蔬菜产区最常见和危害最大的害虫之一。与其他国家一样，土耳其对土耳其真叶螨的防治主要依赖杀螨剂。然而，土耳其真叶螨的抗药性发展迅速，化学防治经常失败。本研究在土耳其从蔬菜作物中采集的 10 个土耳其真叶螨种群中，对各种杀螨剂的毒性进行了调查。此外，还对种群中目前已知的靶标抗性突变进行了筛选。结果表明，对溴氰菊酯的抗性最为普遍，但也有一半的种群对阿维菌素和噻虫嗪具有抗性。在不同种群中发现了电压门控钠离子通道（VGSC）和几丁质合成酶 1 的抗性突变。此外，首次报道了土耳其种群中 VGSC 的 F1538I 和 L1024V 突变。未检测到赋予阿维菌素、吡丙醚和甲氰菊酯等杀螨剂抗性的突变。这些结果将有助于在土耳其制定有效的抗性管理方案。
