肖尔沃特湾军事训练区（英语：Shoalwater Bay military training area，缩写SWBTA），位于澳大利亚昆士兰州罗克汉普顿以北50-80公里处，面积2，713公里（2），是澳大利亚及其盟国军队的训练基地。1998年3月至2000年2月，每月收集蚊子在15个地点进行了二氧化碳诱饵陷阱，研究蚊子的季节性发生和罗斯河病毒（RRV）和巴马森林病毒（BFV）的蚊子。共收集了72，616只蚊子，包括3，897个池，并使用逆转录酶-聚合酶链反应测试了2，428个池。共有15个蚊子池对病毒呈阳性，10个RRV和5个BFV呈阳性。通过凝胶扩散试验对另外763只蚊子的血粉进行了测试，其中大多数（96%）来自袋鼠，袋鼠是研究地区最常见的哺乳动物。结果表明，环喙库蚊和黄绿绒螯蚊是西南边境口岸RRV的主要传播媒介。
Shoalwater Bay military training area (SWBTA), 2,713 km(2) of land located 50-80 km north of Rockhampton, Queensland, Australia, is used by Australian and allied forces for training purposes. Between March 1998 and February 2000, monthly collections of mosquitoes at 15 sites were conducted using carbon dioxide-baited traps to study the seasonal occurrence of mosquitoes and Ross River virus (RRV) and Barmah Forest virus (BFV) in mosquitoes. A total of 72,616 mosquitoes, comprising 3,897 pools were collected, and 2,428 pools were tested using a reverse transcriptase-polymerase chain reaction. A total of 15 pools of mosquitoes were positive for virus, 10 RRV and five BFV. Blood meals from an additional 763 mosquitoes were tested by a gel diffusion assay, and the majority (96%) of those identified were from kangaroo, which was the most common mammal in the study area. The results indicate that Culex annulirostris Skuse and Ochlerotatus vigilax (Skuse) are the main vectors of RRV at SWBTA.
