Native to the Eastern United States and Eastern Canada, Aedes triseriatus (eastern tree hole mosquito) is an important vector of La Crosse virus and dog heartworm. Although its range has been well characterized in the United States, few studies have surveyed its distribution within Canada. In this study, mosquitoes were collected from a variety of urban and rural communities throughout Manitoba, Canada between the years of 2018 and 2020. Aedes triseriatus was identified and confirmed molecularly to be present in 13 communities. This includes localities that expand the species known distribution to new northern and western areas, and suggests that past surveillance efforts have not been comprehensive or environmental factors have caused this mosquito species to be present in areas in which it was not found previously. As Canada is showing signs of a changing climate, this may be driving the broader occurrence of Ae. triseriatus.
原产于美国东部和加拿大东部，白纹伊蚊（东部树洞蚊）是拉哥斯病毒和犬心丝虫的重要传播媒介。尽管其分布范围在美国已得到很好的描述，但很少有研究调查其在加拿大境内的分布情况。在这项研究中，2018 年至 2020 年间，从加拿大曼尼托巴省的各种城市和农村社区收集了蚊子。鉴定并通过分子确认白纹伊蚊存在于 13 个社区。这包括将该物种已知分布范围扩大到新的北部和西部地区的地点，并表明过去的监测工作不够全面，或者环境因素导致这种蚊子出现在以前没有发现的地区。随着加拿大显示出气候变化的迹象，这可能是导致白纹伊蚊更广泛出现的原因。
