Environmental suitability of the red spider mite Tetranchus cinnabarinus (Acari: Tetranychidae) among cassava in China

摘要

The red spider mite (Tetranchus cinnabarinus Boisduval) is one of the main pests in the world and the risk of invasion posed by this mite is becoming more and more serious with regard to increasing areas of planting cassava in China. It is urgent to analyze the potential geography distribution of T. cinnabarinus among cassava in China. The environmental suitability of T. cinnabarinus in China was studied in this paper using Maxent and ArcGIS, based on the biological data and known distribution of T. cinnabarinus. The results showed that there were 4 levels of suitability assessment of T. cinnabarinus in China. The prediction showed T. cinnabarinus mainly distributed in South China, especially in Hainan, Guangdong and Guangxi provinces. The potential geographic distribution of T. cinnabarinus in China defined in this paper constructed the theory basis and technical support for scientifically forming of control measures for T. cinnabarinus in China.
