The Hindustan citrus mite, Schizotetranychus hindustanicus Hirst (Acari: Tetranychidae), is a quarantine pest present in the state of Roraima, Brazil. This mite, which was described in India in 1924, was reported in 2002 in Venezuela and spread to Roraima, where it was reported in 2008, and to Colombia, where it was reported in 2010. Its possible spread to other regions of Brazil is a threat to Brazilian citriculture. This study reports the current distribution of S. hindustanicus and potential predators of this pest and other mites associated with citrus in Roraima. A survey was conducted in August and September 2015 in the 15 municipalities of the state. In each municipality, orchards and citrus plants in backyards and public areas along highways and in urban areas were sampled. Samples of leaves and fruits were collected to identify the mite and its natural enemies. Schizotetranychus hindustanicus was found in all 15 municipalities in the state of Roraima. In total, 308 associated mites were found, with S. hindustanicus being the most abundant phytophagous mite, followed by Brevipalpus yothersi Baker. Amblyseius aerialis (Muma) was the most abundant predator, followed by Iphiseiodes zuluagai Denmark and Muma and Euseius concordis (Chant). The broad dispersal of S. hindustanicus in Roraima increases the risks of this pest reaching the main citrus-producing regions in Brazil.
印度斯坦柑橘螨，即裂爪叶螨（Schizotetranychus hindustanicus Hirst）（蜱螨亚纲：叶螨科），是巴西罗赖马州的一种检疫性害虫。这种螨于1924年在印度被描述，2002年在委内瑞拉被报道，随后传播至罗赖马州（2008年在此被报道）以及哥伦比亚（2010年在此被报道）。它有可能传播到巴西的其他地区，这对巴西的柑橘种植业构成威胁。本研究报告了印度斯坦柑橘螨在罗赖马州的当前分布情况，以及该害虫和与柑橘相关的其他螨类的潜在捕食者。2015年8月和9月在该州的15个市进行了一项调查。在每个市，对果园以及公路沿线和市区公共区域后院中的柑橘植株进行了采样。采集叶片和果实样本以鉴定螨类及其天敌。在罗赖马州的所有15个市均发现了印度斯坦柑橘螨。总共发现了308只相关螨类，其中印度斯坦柑橘螨是数量最多的植食性螨类，其次是尤氏短须螨（Brevipalpus yothersi Baker）。空中钝绥螨（Amblyseius aerialis (Muma)）是数量最多的捕食者，其次是祖鲁钝绥螨（Iphiseiodes zuluagai Denmark and Muma）和康氏钝绥螨（Euseius concordis (Chant)）。印度斯坦柑橘螨在罗赖马州的广泛分布增加了这种害虫扩散到巴西主要柑橘产区的风险。
