This paper describes the temporal and spatial abundance of the mosquito fauna of the Ross River Dam (Stage 1) in northern Queensland, Australia. Culex annulirostris, Anopheles annulipes s.l., Mansonia uniformis, Mansonia septempunctata, and the nondam breeding Aedes vigilax were the major species collected by dry ice-supplemented light traps set at various distances from the edge of the reservoir. To estimate the level of arbovirus activity in these different zones, sentinel chicken flocks were bled 4 times a year and their antibody conversion rates determined by the hemagglutination-inhibition test. Although mosquito abundance at sites close to the reservoir were 1.5-6.1 times higher than at the more distant sites, arbovirus conversion rates, particularly to the alphaviruses Ross River and Sindbis, varied according to zone and year, suggesting that risk of infection was no greater around the dam than elsewhere.
本文描述了澳大利亚昆士兰州北部罗斯河大坝（第一阶段）蚊虫动物群的时空丰度。环喙库蚊、环纹按蚊复合组、纯色曼蚊、七点曼蚊，以及不在大坝繁殖的警觉伊蚊是通过在距水库边缘不同距离处设置的补充干冰的诱蚊灯诱捕到的主要物种。为了估计这些不同区域虫媒病毒的活动水平，每年对哨兵鸡群采血4次，并通过血凝抑制试验测定其抗体转化率。尽管靠近水库的地点蚊虫丰度比距离较远的地点高1.5至6.1倍，但虫媒病毒转化率，尤其是罗斯河病毒和辛德毕斯病毒等甲病毒的转化率，因区域和年份而异，这表明大坝周围的感染风险并不比其他地方更高。
