Diel patterns of human host attack by Aedes albopictus in the laboratory were studied in relation to mosquito body size, age, parity, and time of day. Analysis of responses in 10-, 15-, and 20-day-old females indicated a significant main effect due to time of observation in the diel period, as well as significant time x parity and time x age interactions. The distribution of mean host attack responses during the diel period was bimodal with approximately 70% of all activity during photophase (0800-2000 h); attack rates were highest in the morning (0800 h) and evening (1400-2000 h) and lowest between 0200 and 0600 h. The diel pattern of attack responses was bimodal for nulliparous and parous females, but parous females were more active than nulliparous females between 1400 and 2000 h. This pattern became increasingly bimodal during photophase, as mosquitoes aged, regardless of mosquito body size or parity. Variations in host avidity patterns between young and old females suggest that mosquito repellent bioassays initiated early in the day, that last > or = 6 h, or that use young females (approximately 5 days old) overestimate the protection period of deet against mosquitoes > 10 days old.
在实验室中研究了白纹伊蚊对人类宿主的攻击昼夜模式，该模式与蚊子的体型、年龄、产次和时间有关。对10日龄、15日龄和20日龄雌蚊反应的分析表明，在昼夜期间，观察时间产生了显著的主效应，以及时间×产次和时间×年龄的显著交互作用。昼夜期间平均宿主攻击反应的分布是双峰的，在光照期（08:00-20:00）所有活动约占70%；攻击率在早晨（08:00）和傍晚（14:00-20:00）最高，在02:00至06:00之间最低。未产卵雌蚊和已产卵雌蚊的攻击反应昼夜模式均为双峰，但已产卵雌蚊在14:00至20:00之间比未产卵雌蚊更活跃。随着蚊子年龄增长，在光照期这种模式的双峰性越来越明显，与蚊子的体型或产次无关。年轻雌蚊和年老雌蚊宿主偏好模式的差异表明，在一天中较早开始、持续≥6小时或使用年轻雌蚊（约5日龄）的驱蚊生物测定法，高估了避蚊胺对10日龄以上蚊子的保护期。
