摘要: 目的 观察新疆额尔齐斯河下游北湾地区蚊虫季节消长情况。方法 选择北湾地区3种生境,从4月开始至蚊虫活动消失,每月上、中、下旬调查3次,每次在日出前、后1h,日落前、后1h以及12:00、16:00做人帐诱蚊虫密度调查。结果 在3种生境中营院外树林蚊虫密度最大,营院内树林和营院外荒漠蚊虫密度较低,刺扰伊蚊是室外3种生境的优势蚊种(90.18%~96.83%),里海伊蚊在荒漠生境中数量较多(9.78%);蚊虫4月中旬出现,9月初活动消失,6-7月为北湾地区蚊虫活动高峰;不同生境及不同蚊种其季节消长曲线不同。结论 北湾地区各种生境中蚊虫密度都较高,特别是野外树林茂密、杂草丛生的生境,在6-7月蚊虫活动高峰时间危害十分严重。

Abstract: Objective To study the season variety of mosquito at Beiwan region of the lower reach of the river Erqis,Xinjiang. Methods Using human-baited bed net method to collect mosquitoes in different habitats six times a day and once every ten days from April to September. Results The density of mosquitoes in the wood out of the camp court was the highest and that in the woods in the camp court and the desert out of the camp court was lower. Aedes vexans(90.18%-96.83%) was the dominant species in all the habitats. The amount of Aedes caspius(9.78%) in the desert was more than the other two habitats. The mosquitoes came to appear in the middle ten days of April and disappeared in the first ten days of September. The active peak was from June to July for mosquitoes at Beiwan. The curves of season distribution were different in distinct habitats for different species. Conclusion The density of mosquitoes was fairly high in all the three habitats,especially in the heavy wood and grass. The harm of mosquitoes was very serious from June to July at Beiwan region.
