Aedes notoscriptus (Skuse) mosquitoes colonized from Brisbane, Queensland, Australia, were fed on blood containing Ross River (RR) virus isolated from Brisbane, Queensland, Australia. This colony was highly susceptible to infection, ID50 = 10(3.2) CCID50 per mosquito, with titers in infected mosquitoes peaking 9 d after infection. Transmission occurred between days 9 and 14, with a maximum rate of 13% between days 12 and 14 after infection. Considering the peridomestic abundance and human blood feeding habit of Ae. notoscriptus, positive transmission of RR virus indicates the need to consider this species more seriously in the context of urban RR transmission.
从澳大利亚昆士兰州布里斯班采集的致倦库蚊（Skuse）被喂食含有从澳大利亚昆士兰州布里斯班分离出的罗斯河（RR）病毒的血液。该蚊群对感染高度敏感，半数感染剂量（ID50）为每只蚊子10(3.2) 组织培养感染剂量50（CCID50），感染蚊子的病毒滴度在感染后9天达到峰值。传播发生在第9天至第14天之间，感染后第12天至第14天的传播率最高，为13%。考虑到致倦库蚊在住宅周边的数量以及吸食人血的习性，RR病毒的阳性传播表明在城市RR传播背景下需要更严肃地考虑该蚊种。
