摘要
为调查新疆北湾地区刺扰伊蚊的吸血习性，2004～2005年6～8月在蚊虫活动高峰季节，在新疆额尔齐斯河下游北湾地区，通过采集宿主体表及家畜棚舍内蚊虫，每旬调查一次刺扰伊蚊在人房、猪舍内的密度，以人、马、牛为饵进行诱捕和调查昼夜24h吸血节律等方式，研究北湾地区优势蚊种刺扰伊蚊的吸血宿主、吸血趋性以及吸血节律。调查发现，北湾地区刺扰伊蚊在野外蚊虫种群数量组成中占89．61％，在猪舍内占90．78％，在人房内占55．20％，表明刺扰伊蚊主要栖息活动在野外以及家畜棚舍内。吸血趋性实验表明，刺扰伊蚊的吸血宿主广泛，人和马、牛、猪等家畜血液兼吸，并且偏嗜马、牛、猪血；日落前1h，刺扰伊蚊对人、马、牛的趋吸比例为1：18．58：9．84，人、马在1天中平均的趋吸比例为1：38．67。刺扰伊蚊在白天和夜晚都有吸血活动，但呈现出规律的晨、昏峰，晨峰最高峰在日出前1h，昏峰最高峰在日落后1h。研究表明刺扰伊蚊对人畜的刺叮危害十分严莺，在当地蚊虫刺叮吸血高峰时间应加强室内外人员的个体防护以及对家禽家畜的保护。
Aedes vexans is a dominant mosquito species in Beiwan region, Xinjiang, China. In order to investigate the bleeding habit in successive 24 h, as well as the host and blood preference, collection of Ae. vexans was performed at the active time of mosquitoes from June to August of 2004 and 2005 in Beiwan region. Cattle shed was selected as the collection site with human, equine and cattle as bait, and the population density was recorded as well. The results showed that Ae. vexans is the prevalent species in field （89.61% ）, pigsty （90.78%） and room （55.20%）. Ae. vexans may feed on human, equine, cattle and swine, but the equine, bovine and swine blood appeared to be their preference. The feeding preference of Ae. vexans to Human, Horse and cattle was 1 ： 18.58 ： 9.84 one hour before sunset. The bleeding activity happened in two obvious peak periods, one hour before sunrise and one hour after sunset, respectively. As the serious harm of Ae. vexans biting, individual protection and livestock preservation are necessary at the peak period of mosquito activaties.
