The two-spotted spider mite Tetranychus urticae causes significant damage to ornamental, cotton, sugarcane and horticultural crops in Australia. It has a long history of developing resistance to many acaricides including bifenazate. A mutation in the conserved cd1- and ef-helices of the Qo pocket of cytochrome b is recognized as the primary mechanism of bifenazate resistance. To investigate the resistance mechanisms against bifenazate in Australian two-spotted spider mite, we sequenced the complete mitochondrion genome of five mite strains including a susceptible and bifenazate-resistant strain.

线粒体细胞色素 b 中的一个新突变赋予二斑叶螨 Tetranychus urticae Koch（螨虫：叶螨科）对联苯那酯的抗性

二斑叶螨（Tetranychus urticae）对澳大利亚的观赏作物、棉花、甘蔗和园艺作物造成严重损害。它对包括联苯那酯在内的许多杀螨剂产生抗药性有着悠久的历史。细胞色素 b Qo 口袋的保守 cd1- 和 ef- 螺旋的突变被认为是联苯那酯耐药的主要机制。为了研究澳大利亚二斑叶螨对联苯那酯的抗性机制，我们对五种螨虫菌株的完整线粒体基因组进行了测序，其中包括敏感菌株和联苯酯抗性菌株。
