Aedes taeniorhynchus were collected on the wing at several times during the day and night, in Indian River and Brevard County, Florida. Nonblooded females were individually analyzed for fructose and glycogen. Fructose content of mosquitoes collected early in the morning and held without food during the day diminished to approximately the same level as in mosquitoes collected late in the afternoon. However, fructose content of mosquitoes collected before sunset and held without food overnight diminished greatly, whereas that of mosquitoes collected in the morning always exceeded that of evening collections. Maximum fructose content occurred within one or 2 hours after sunset. Apparently, these mosquitoes take little or no nectar during the day, and feed soon after the onset of darkness.
在佛罗里达州印第安河县和布雷瓦尔德县，于白天和夜间的不同时段采集了带纹伊蚊。对未吸血的雌蚊个体进行了果糖和糖原分析。清晨采集且白天未喂食的蚊子，其果糖含量降至与下午晚些时候采集的蚊子大致相同的水平。然而，日落前采集且整夜未喂食的蚊子，其果糖含量大幅下降，而清晨采集的蚊子的果糖含量始终超过傍晚采集的蚊子。果糖含量在日落后1至2小时内达到最高。显然，这些蚊子在白天很少或根本不摄取花蜜，而是在夜幕降临后不久就进食。
