First report of Tetranychus evansi in China

Tetranychus evansi (Acari: Tetranychidae - EPPO A2 List) is reported for the first time from China. The pest was detected in three provinces (Guangdong, Guangxi and Sichuan) during studies conducted in 2016/2017. T. evansi was found on tomato (Solanum lycopersicum) in Ya’an (Sichuan); on aubergine (S. melongena) in Baise, Guangzhou and Ya’an (Guangxi, Guangdong and Sichuan, respectively); and in cucumber (Cucumis sativus) in Chengdu (Sichuan). The identity of the pest was confirmed by morphological and molecular methods. It is concluded that T. evansi may represent a new threat to tomato production in China and that further studies on its geographical distribution and incidence are needed.

The situation of Tetranychus evansi in China can be described as: Present, only in some areas (Guangdong, Guangxi and Sichuan provinces).
