Adaptation of acaricide stress facilitates Tetranychus urticae expanding against Tetranychus cinnabarinus in China.

ABSTRACT: The two-spotted spider mite, Tetranychus urticae, and the carmine spider mite, Tetranychus cinnabarinus, are invasive and native species in China, respectively. Compared with T. cinnabarinus, T. urticae has expanded into most parts of China and has become the dominant species of spider mite since 1983, when it was first reported in China. However, the mechanism of the demographic conversion has not been illuminated. In this study, one T. urticae field population and one T. cinnabarinus field population were isolated from the same plant in the same field, and the toxicological characteristics were compared between these two species. Laboratory bioassays demonstrated that T. urticae was more tolerant to commonly used acaricides than T. cinn
