Among pests that have recently been introduced into the Americas, the red palm mite, Raoiella indica Hirst (Prostigmata: Tenuipalpidae), is the most invasive. This mite has spread rapidly to several Caribbean countries, United States of America, Mexico, Venezuela, Colombia and Brazil. The potential dispersion of R. indica to other regions of South America could seriously impact the cultivation of coconuts, bananas, exotic and native palms and tropical flowers such as the Heliconiaceae. To facilitate the development of efficacious R. indica management techniques such as the adoption of phytosanitary measures to prevent or delay the dispersion of this pest, the objective of this paper was to estimate the potential geographical distribution of R. indica in South America using a maximum entropy model. The R. indica occurrence data used in this model were obtained from extant literature, online databases and field sampling data. The model predicted potential suitable areas for R. indica in northern Colombia, central and northern Venezuela, Guyana, Suriname, east French Guiana and many parts of Brazil, including Roraima, the eastern Amazonas, northern Pará, Amapá and the coastal zones, from Pará to north of Rio de Janeiro. These results indicate the potential for significant R. indica related economic and social impacts in all of these countries, particularly in Brazil, because the suitable habitat regions overlap with agricultural areas for R. indica host plants such as coconuts and bananas.
在最近引入美洲的害虫中，印度红棕榈螨 Raoiella indica Hirst（Prostigmata：Tenuipalpidae）是最具入侵性的。这种螨虫已迅速传播到加勒比地区的几个国家、美国、墨西哥、委内瑞拉、哥伦比亚和巴西。R. indica 向南美洲其他地区的潜在扩散可能会严重影响椰子、香蕉、外来和本地棕榈以及热带花卉（如 Heliconiaceae）的种植。为了促进有效的 R. indica 管理技术的发展，例如采取植物检疫措施来防止或延迟这种害虫的扩散，本文的目的是使用最大熵模型估计 R. indica 在南美洲的潜在地理分布。该模型中使用的 R. indica 发生数据来自现有文献、在线数据库和实地采样数据。该模型预测了哥伦比亚北部、委内瑞拉中部和北部、圭亚那、苏里南、法属圭亚那东部以及巴西的许多地区（包括罗赖马、亚马逊东部、帕拉北部、阿马帕和沿海地区，从帕拉到里约热内卢北部）可能适合 R. indica 的地区。这些结果表明，在所有这些国家，特别是在巴西，R. indica 可能会带来重大的经济和社会影响，因为适宜栖息地与 R. indica 宿主植物（如椰子和香蕉）的农业区重叠。
