Abstract

Background: The presence of Aedes albopictus in Bolivia has been a subject of controversy, with a lack of concrete documentation.

Objectives: This study aimed to provide evidence of Ae. albopictus presence in Bolivia.

Methods: Larval habitats were sampled in Rosario del Yata and San Agustín, Guayaramerín Municipality, Beni Department, northern Bolivia. Collected mosquito larvae were reared to the L4 and adult stages for morphological identification, with some specimens sequenced for confirmation.

Findings: Aedes albopictus was identified in multiple larval habitats within peridomestic areas, such as buckets, canisters, and cut plastic bottles used as flower vases in both localities, confirming its establishment in the area. This represents the first concrete documentation of the species in Bolivia. The collections (larvae and adults) have been deposited in the Medical Entomology Laboratory of the Universidad Mayor de San Simón in Cochabamba, Bolivia, and the Laboratory of Entomology of the Instituto Nacional de Laboratorios de Salud of the Ministry of Health in La Paz, Bolivia.

Main conclusion: Given its role as a vector for arboviruses such as dengue and Chikungunya, Ae. albopictus should be incorporated into the Bolivian National Programme of Vector Control for monitoring.

玻利维亚白纹伊蚊（Stegomyia）存在的第一份具体文献：消除以前的轶事。

背景：白纹伊蚊在玻利维亚的存在一直存在争议，缺乏具体的文献资料：本研究旨在提供白纹伊蚊在玻利维亚存在的证据：方法：在玻利维亚北部贝尼省 Guayaramerín 市 Rosario del Yata 和 San Agustín 的幼虫栖息地取样。采集的蚊子幼虫饲养到 L4 和成虫阶段，进行形态鉴定，并对一些标本进行测序确认：白纹伊蚊在两个地方的水桶、罐子和用作花瓶的塑料瓶等近郊区域的多个幼虫栖息地被发现，证实了白纹伊蚊在该地区的存在。这是该物种在玻利维亚的首次具体记录。采集的昆虫（幼虫和成虫）已存放在玻利维亚科恰班巴的圣西蒙市长大学医学昆虫学实验室和玻利维亚拉巴斯卫生部国家健康实验室研究所的昆虫学实验室：主要结论：鉴于白纹伊蚊是登革热和基孔肯雅热等虫媒病毒的传播媒介，应将其纳入玻利维亚国家病媒控制计划进行监测。

期刊介绍： Memórias do Instituto Oswaldo Cruz is a journal specialized in microbes & their vectors causing human infections. This means that we accept manuscripts covering multidisciplinary approaches and findings in the basic aspects of infectious diseases, e.g. basic in research in prokariotes, eukaryotes, and/or virus. Articles must clearly show what is the main question to be answered, the hypothesis raised, and the contribution given by the study. Priority is given to manuscripts reporting novel mechanisms and general findings concerning the biology of human infectious prokariotes, eukariotes or virus. Papers reporting innovative methods for diagnostics or that advance the basic research with these infectious agents are also welcome. It is important to mention what we do not publish: veterinary infectious agents research, taxonomic analysis and re-description of species, epidemiological studies or surveys or case reports and data re-analysis. Manuscripts that fall in these cases or that are considered of low priority by the journal editorial board, will be returned to the author(s) for submission to another journal.
