白纹伊蚊自1985年在美国发现以来,已证明可以传播多种蚊媒病毒病。本文的目的是调查北美温带区白纹伊蚊的吸血宿主类型。蚊虫标本的采集和制备:于1989年8～9月和1990年6～9月,在密苏里州华盛顿县Potosi东北部的废轮胎堆和周围的树丛中,用吸蚊器、扫网、人诱和干冰灯诱捕蚊,鉴定种类后,按腹部血食消化程度分级(0～4级),将吸血蚊腹部在0.4ml缓冲液中研碎,低温保存。测试程序:血食测定用沉淀管(PPT)和ELISA方法进行,蚊虫悬液先用PPT法测试哺乳动物和鸟的抗血清。鸟血清阳性标本进一步用雀、鸽、鹌鹑和鹳等鸟类的
Since Aedes albopictus was discovered in the United States in 1985, it has been demonstrated that a variety of mosquito vectors can be transmitted. The purpose of this article is to investigate the blood-sucking hosts of Aedes albopictus in the temperate zone of North America. Collection and preparation of mosquito specimens: Mosquito traps, sweeping nets, artificial lures And dry ice lamp trapping mosquitoes, identification of species, according to the level of abdominal blood digestion (grade 0 to 4), the snout abdomen in 0.4ml buffer grinding, cryopreservation. Test Procedures: The blood test was performed with a precipitation tube (PPT) and an ELISA method. The mosquito suspension was first tested for antisera in mammals and birds by the PPT method. Bird seropositive specimens were further treated with birds, birds, quails and storks
