木薯单爪螨全球潜在地理分布的MaxEnt预测

Prediction of worldwide potential geographic distribution of Mononychellus tanajoa with MaxEnt

木薯单爪螨(Mononychellus tanajoa Bondar)是木薯产区重要的毁灭性害螨之一,是世界上重要的具有检疫意义的有害生物。本文利用MaxEnt软件预测全球范围内气候条件适宜该虫存活的区域,在此基础上结合寄主分布预测了木薯单爪螨的全球潜在地理分布。预测结果显示,在104个木薯种植国家或地区中,除了非洲北部和亚洲部分木薯种植国外,该螨在其余国家或地区的生存适宜值均大于10,为该螨的潜在地理分布区,加强这些区域的调查监测对保护当地木薯种植有重要意义。

Mononychellus tanajoa Bondar,one of the most serious pests in Cassava planting areas,was one of the most important quarantine pests worldwide.In this paper,the areas with suitable climate conditions for the M.tanajoa survival were predicted using MaxEnt software,based on which,the worldwide potential geographic distribution of the M.tanajoa were predicted combinging the parastisu distribution.The results showed that among 104 cassava planting countries or regions,except the north Africa and part areas of Asian,the suitable survival values of the M.tanajoa are all above 10,defined as the potential geographic distribution of the M.tanajoa.Thus,enhancing the investigation and monitoring of the M.tanajoa in these areas has great effect on the local Cassava planting.
