日本脑炎是亚洲的一种重要疾病，自1995年以来，其范围已扩展到澳大利亚北部。库蚊属库蚊亚群的环喙库蚊Skuse被认为是最可能的蚊媒。由于错误鉴定以前发生在这个亚组，我们的文件定义电泳方法来识别库蚊标本从昆士兰州和北领地在澳大利亚和来自西部省在巴布亚新几内亚。在1996年至1998年的采集中，库蚊Wiedemann，Cx。palpalis Taylor和Cx. annulirostris包括93.1%的总登陆长鼻库蚊收集，6.9%仍然不明物种的形态或电泳检查。Cx的患病率。“须”的数值变化不定，似乎与一九九七年的降雨量低于平均水平有关。在巴布亚新几内亚，这一物种包括高达97.4%的带状长鼻库蚊，从托雷斯海峡岛，mds和约克角收集的数量较少;没有从其他昆士兰州地方收集。库蚊annulirostris在平均或高于平均降雨量的年份更为普遍，在大多数地区占优势，特别是在托雷斯海峡和昆士兰州。这些数据证实了分离Cx中存在的问题。sitiens从Cx，palpalis和Cx，annulirostris形态特征。
Japanese encephalitis is a disease of major importance in Asia, which from 1995 has extended its range into the north of Australia. Culex annulirostris Skuse of the Culex sitiens subgroup of Culex was incriminated as the most likely mosquito vector. Because misidentifications previously have occurred within this subgroup, our paper defines electrophoretic methods to identify Culex specimens from Queensland and the Northern Territory in Australia and fi om Western Province in Papua New Guinea. In collections from 1996 to 1998 Culex sitiens Wiedemann, Cx. palpalis Taylor, and Cx. annulirostris comprised 93.1% of the total Landed proboscis Culex mosquitoes collected; 6.9% remained unidentified to species by morphological or electrophoretic examination. The prevalence of Cx.. palpalis was variable and appeared to be associated with below average rainfall during 1997. In Papua New Guinea, this species comprised up to 97.4% of banded proboscis Culex, with smaller numbers collected from the Torres Strait Isl;mds and Cape York; none was collected from other Queensland localities. Cx. annulirostris was more prevalent during years of average or above average rainfall and was predominant in most localities, especially in the Torres Strait and Queensland. These data confirmed the problems in separating Cx. sitiens From Cx, palpalis and Cx, annulirostris using morphological characters.
