摘要: 目的 了解河西走廊地区蚊媒传染病传播媒介分布情况, 进一步确认河西走廊地区为无流行性乙型脑炎(乙脑)及其他蚊媒传染病地区。方法 采用灯诱法和人工小时法。灯诱法:用功夫小帅牌吸入式诱蚊灯悬挂于每个调查点离地面0.8~1.5 m处, 每次开灯诱捕12 h;人工小时法:采集者手持电动吸蚊器或口吸吸蚊管在人房、居民区楼道、猪圈、牛棚捕获蚊虫, 捕蚊时间一般为30~40 min。结果 共采集蚊虫23 584只, 通过初步鉴定, 发现该地区蚊虫4属18种。在所捕获蚊虫中, 数量最多的生境为畜舍, 占捕获总数的76.39%, 农户次之, 占14.23%, 居民区最少, 占4.49%。淡色库蚊、刺扰伊蚊为优势蚊种, 分别占捕获总数的55.87%和23.04%, 几乎分布整个河西5市。未捕获到乙脑主要传播媒介三带喙库蚊, 病毒检测未检出乙脑病毒, 但在该地区首次发现蚊传黄病毒和辽宁病毒, 且病毒阳性检出率较高。结论 河西走廊地区蚊虫种群分布较为广泛, 部分水系分布较为丰富的区域种群密度较高;今后应加强该地区蚊虫孳生地清理工作;河西地区蚊虫携带病毒的研究不可懈怠。

Abstract: Objective To investigate the distribution of vectors of mosquito?borne diseases in the Hexi Corridor of Gansu province, China and to further confirm the Hexi Corridor as the area free of Japanese encephalitis (JE) and other mosquito?borne diseases. Methods The light?trap method and labor hour method were used to capture mosquitoes. In the light?trap method, the suction?type mosquito lamp (Kung Fu Xiaoshuai) was hung 0.8-1.5 m above the ground at each investigation point, and the mosquito lamp worked for 12 hour each time. In the labor hour method, the hand?held electric mosquito trap or mouth suction?type mosquito trap was used to capture mosquitoes in the human house, residential passageway, pigsty, and cowshed for 30-40 min. Results A total of 23 584 mosquitoes were collected, which, as preliminarily identified, belonged to 18 species and 4 genera. Most of the captured mosquitoes were from animal houses, accounting for 76.39%, followed by farmer’s households, accounting for 14.23%, and the last one was residential area, from which 4.49% of mosquitoes were captured. Culex pipiens pallens and Aedes vexans were the dominant species, which accounted for 55.87% and 23.04%, respectively, of all mosquitoes and were distributed almost throughout the 5 cities in Hexi Corridor area. Culex tritaeniorhynchus, the main vector of JE, was not captured, and JE virus was not detected. However, mosquito?borne flavivirus and Liaoning virus were first found in this area, with a relatively high detection rate. Conclusion Various species of mosquitoes are widely distributed in the Hexi Corridor, and the mosquito population density is relatively in raprian areas. Cleanup of mosquito breeding sources should be strengthened, and the research on mosquito?borne viruses in the Hexi Corridor cannot be neglected.
