The responses of Japanese encephalitis virus (JEV) mosquito vectors to 1-octen-3-ol (octenol) and CO2 were evaluated using Centers for Disease Control (CDC) light traps at 3 sites in northern Australia. There was no significant difference between the number of Culex sitiens subgroup mosquitoes or Cx. gelidus collected in CDC light traps baited with either CO2 alone or CO2 + octenol on Badu Island. At both mainland locations, using octenol in combination with CO2 significantly increased collections of Cx. sitiens subgroup mosquitoes. Collections of nontarget species, such as Ochlerotatus spp., Anopheles spp., and Verrallina spp. were also significantly increased with the addition of octenol. At all 3 locations, reducing collections of nontarget mosquitoes by not using octenol increased the proportion of Culex spp. collected, thus potentially reducing the time and resources required to sort and process collections for JEV detection. Our results also indicate that trials into the efficacy of using octenol as an attractant should be carried out in each area prior to the implementation of a mosquito-based arbovirus surveillance system.
在澳大利亚北部的3个地点，使用疾病控制中心（CDC）诱蚊灯对日本脑炎病毒（JEV）蚊媒对1-辛烯-3-醇（辛烯醇）和二氧化碳的反应进行了评估。在巴杜岛，单独用二氧化碳或二氧化碳+辛烯醇诱饵的CDC诱蚊灯捕获的致倦库蚊亚组蚊子或杰氏库蚊数量之间没有显著差异。在两个大陆地点，将辛烯醇与二氧化碳结合使用显著增加了致倦库蚊亚组蚊子的捕获量。添加辛烯醇后，诸如奥氏蚊属、按蚊属和维氏蚊属等非目标物种的捕获量也显著增加。在所有3个地点，不使用辛烯醇减少非目标蚊子的捕获量，增加了库蚊属蚊子的捕获比例，从而有可能减少为检测JEV而对捕获物进行分类和处理所需的时间和资源。我们的结果还表明，在实施基于蚊子的虫媒病毒监测系统之前，应在每个地区开展关于使用辛烯醇作为引诱剂效果的试验。
