Aedes albopictus is native to Asia and is ranked among the top 100 invasive species worldwide, with vector competence for dengue, Zika, and chikungunya viruses. Understanding Ae. albopictus dispersal is essential for effective monitoring and vector control strategies. In this study, we analysed and updated the distribution of Ae. albopictus in Brazil using data available from the Ministry of Health through the Rapid Index Survey for Aedes (LIRA) for the years 2015-2020. The results of this research were mapped to visually represent the current distribution of Ae. albopictus in Brazil. In 2015, the presence of the vector was confirmed in 271 of the 1,820 Brazilian municipalities sampled (14.9%), and in 2020 it was detected in 728 of the 2,937 municipalities sampled (24.8%). In 2020, all Brazilian states had recorded the presence of this critical vector with a broader geographic distribution in the Southeast and Midwest regions as compared to the North, Northeast, and South regions. It was possible to note some stabilization of dispersion of this species in the Brazilian territory. The record of Ae. albopictus distribution advanced in Brazilian states and municipalities from 2015 to 2020; it is suggested that surveys of this vector be conducted periodically in all Brazilian municipalities and authorities should developing control strategies for this species together with Ae. aegypti.
白纹伊蚊原产于亚洲，被列为世界上 100 种最具入侵性的物种之一，对登革热、寨卡和基孔肯雅热病毒具有媒介能力。了解白纹伊蚊的扩散对于有效监测和控制媒介策略至关重要。在这项研究中，我们分析并更新了 2015 年至 2020 年期间通过卫生部通过快速伊蚊指数调查（LIRA）获得的数据在巴西的白纹伊蚊分布。本研究的结果被绘制出来，以直观地表示巴西目前白纹伊蚊的分布情况。2015 年，在抽样的 1820 个巴西市政当局中有 271 个（14.9%）确认存在该媒介，而 2020 年在抽样的 2937 个市政当局中有 728 个（24.8%）检测到该媒介。2020 年，巴西所有州都记录到了这种关键媒介的存在，与北部、东北部和南部地区相比，东南部和中西部地区的地理分布更为广泛。可以注意到该物种在巴西境内的扩散有一定程度的稳定。从 2015 年到 2020 年，巴西各州和市政当局对白纹伊蚊分布的记录有所增加；建议在所有巴西市政当局定期对白纹伊蚊进行调查，同时当局应与埃及伊蚊一起制定针对该物种的控制策略。
