山东地区常见蚊种嗜血习性的研究

目的调查和分析山东不同地区蚊类的嗜血习性,并对常见蚊种选择吸血宿主的嗜好作出判断。方法用人帐诱捕法、人体诱捕法、网捕法、人工小时法等采集不同场所的蚊虫,鉴定蚊种后,将其杀死作胃血沉淀试验,对血源相近的宿主在不易鉴别时,采用凝集抑制试验方法。结果从人房、家畜舍及野外共采集蚊虫14种,获得胃血标本13 283份。不同蚊种的偏嗜性不同,淡色库蚊的嗜血范围广泛,但以人血和鸡血为主,兼吸其他动物的血;三带喙库蚊主要嗜吸牛(羊)、马(驴、骡)、猪等家畜血,并兼吸人血;中华按蚊的主要嗜血对象是牛、羊,其次是马、驴、骡、猪,而吸人血者较少;骚扰阿蚊主要吸人血、牛血并兼吸猪、鸡及其他家畜、禽血。另对山东地区其他6种蚊虫也进行了选择吸血宿主嗜好的判断。结论蚊虫对人或不同动物的血液有不同的偏嗜性。
