During the summer 1994 outbreak of epidemic polyarthritis in suburban Brisbane, 29,931 adult female mosquitoes were collected by octenol-CO2 light traps and tested for virus by species in pools of approximately 20 using an in situ enzyme-linked immunoassay. Overall, 63 isolations of Ross River (RR) virus were made from 7 different mosquito species, including 23 from freshwater-breeding Culex annulirostris Skuse, 13 from peridomestic Aedes notoscriptus (Skuse), 4 from Aedes procax (Skuse), 12 from the brackish water-breeding Aedes funereus (Theobald), 9 from saltmarsh Aedes vigilax (Skuse), and 1 each from Culex sitiens Wiedemann and Aedes alternans (Westwood). The RR virus minimum infection rate in mosquitoes ranged from 1.6 to 2.5/1,000 from March to June 1994. This study implicates freshwater and brackish water mosquitoes as important suburban vectors of RR virus and indicates the need for refocusing mosquito control priorities.
在1994年夏季布里斯班郊区流行性多关节炎疫情爆发期间，用诱蚊烯-二氧化碳灯光诱捕器捕获了29,931只成年雌性蚊子，并以大约20只为一组进行分种检测，采用原位酶联免疫分析法检测病毒。总体而言，从7种不同蚊子中分离出63株罗斯河（RR）病毒，其中23株来自在淡水中繁殖的环纹库蚊（Culex annulirostris Skuse），13株来自家栖的致倦库蚊（Aedes notoscriptus (Skuse)），4株来自普罗克斯伊蚊（Aedes procax (Skuse)），12株来自在微咸水中繁殖的丧葬伊蚊（Aedes funereus (Theobald)），9株来自盐沼伊蚊（Aedes vigilax (Skuse)），还有1株分别来自威德曼库蚊（Culex sitiens Wiedemann）和交替伊蚊（Aedes alternans (Westwood)）。1994年3月至6月期间，蚊子中RR病毒的最低感染率在1.6至2.5/1000之间。本研究表明淡水和微咸水蚊子是RR病毒在郊区的重要传播媒介，并指出有必要重新调整蚊虫控制重点。
