Field studies were conducted with EVS (encephalitis vector surveillance) traps in south-eastern Queensland, Australia, to determine the relative response rates of mosquitoes to three levels (0.1, 4.5 and 30 mg/h) of 1-octen-3-ol (octenol) in combination with a standard bait of 2200 g carbon dioxide (CO2), compared with CO2 alone or CO2 with light from a 6V incandescent bulb. Compared to CO2 alone, Aedes vigilax collections increased significantly when CO2 was supplemented by all three octenol emission levels, but not by the addition of light. Furthermore, the 4.5 and 30 mg/h release rate of octenol gave a significant increase in numbers of Ae.vigilax relative to that from CO2+light. In contrast, collections of Culex annulirostris and Culex sitiens were not enhanced significantly by either the addition of light or octenol at all three levels. Fewer Cx sitiens were collected with octenol released at 4.5 mg/h in comparison to CO2 alone. These differential sampling rates should be taken into account when using EVS traps.
在澳大利亚昆士兰州东南部,使用脑炎媒介监测(EVS)诱捕器进行了实地研究,以确定蚊子对与2200克二氧化碳(CO₂)标准诱饵相结合的三种浓度(0.1、4.5和30毫克/小时)的1-辛烯-3-醇(辛烯醇)的相对反应率,并与单独使用CO₂或CO₂加6V白炽灯泡发出的光进行比较。与单独使用CO₂相比,当CO₂添加所有三种辛烯醇排放水平时,警觉伊蚊的捕获量显著增加,但添加光时捕获量没有显著增加。此外,相对于CO₂+光,4.5和30毫克/小时的辛烯醇释放率使警觉伊蚊数量显著增加。相比之下,添加光或所有三种浓度的辛烯醇对环纹库蚊和海滨库蚊的捕获量均未显著提高。与单独使用CO₂相比,以4.5毫克/小时释放辛烯醇时捕获的海滨库蚊较少。使用EVS诱捕器时应考虑这些不同的采样率。
