Abstract

This study reports the results of a molecular screening for Wolbachia (Wb) infection in Aedes albopictus (Skuse) populations recently established in the Yucatan Peninsula, Mexico. To do so, collections of free-flying adults with BG traps and emerged adults from eggs after ovitrap field collections were performed in three suburban localities of the city of Merida, Yucatan. Overall, local populations of Ae. albopictus present a natural Wb infection rate of ~40% (18 of 45). Wb infection was detected in both field-collected adults (76.5%, 13 of 17) and eggs reared (17.8%, 5 of 28) and in 37.9% (11/29) of females and 43.7% (7/16) of male Ae. albopictus mosquitoes. An initial screening for Wolbachia strain typing showed that native Ae. albopictus were naturally coinfected with both wAlbA and wAlbB strains. The knowledge of the prevalence and diversity of Wolbachia strains in local populations of Aedes mosquitoes is part of the baseline information required for current and future Wolbachia-based vector control approaches to be conducted in Mexico.

来自墨西哥尤卡坦半岛的白纹伊蚊（双翅目：lic科）的原种群中的Wolbachia

摘要

这项研究报告了最近在墨西哥尤卡坦半岛建立的白纹伊蚊（Skuse）人群中Wolbachia（Wb）感染分子筛查的结果。为此，在尤卡坦州梅里达市的三个郊区进行了带BG诱捕装置的自由飞行成虫的收集以及卵子田间收集后从卵中出来的成虫的收集。总体而言，大江本地人口。白化病患者的自然Wb感染率约为40％（45中的18）。在野外采集的成年人（76.5％，17个中的13个）和饲养的卵（17.8％，28个中的5个）中都检测到Wb感染，女性中37.9％（11/29），男性43.7％（7/16）中检测到Wb感染e 白化病蚊子。最初对Wolbachia菌株进行分型的筛选结果显示该菌株为天然Ae。白纹伊蚊是自然与两个合并感染wAlbA和wAlbB株。有关伊蚊的当地种群中Wolbachia菌株的流行和多样性的知识，是目前和将来在墨西哥进行的基于Wolbachia的病媒控制方法所需的基本信息的一部分。
