Ten-day-old, parous Aedes aegypti (L.) had a higher threshold of blood meal size for the inhibition of continued host-seeking than did 5 d-old, nulliparous females of the same size. Older females of a smaller-bodied cohort had a higher threshold of blood meal size for the initiation of egg development than did younger females. In contrast, older larger-sized females had a lower blood meal-size threshold for egg development. The blood of paired avian hosts was marked with rubidium and cesium to study the effect of age and body size on the frequency of multiple blood feeding. Chronologically old females had a higher frequency of multiple blood feeding than younger females. In the laboratory, the frequency of multiple blood feeding among larger-sized females was higher than among small-sized females.
10日龄的经产埃及伊蚊（L.）比同样大小的5日龄未产雌蚊对持续寻找宿主的抑制有更高的血餐量阈值。体型较小群体中的老龄雌蚊比年轻雌蚊对启动卵子发育有更高的血餐量阈值。相比之下，体型较大的老龄雌蚊对卵子发育的血餐量阈值较低。用铷和铯标记配对禽类宿主的血液，以研究年龄和体型对多次吸血频率的影响。按时间顺序，老龄雌蚊比年轻雌蚊有更高的多次吸血频率。在实验室中，体型较大雌蚊的多次吸血频率高于体型较小的雌蚊。
