采用卵巢油注射技术对成年雌美根坎坦伊蚊种群的年龄结构进行了研究。结果表明，与普遍观点相反，卵巢囊不会形成淋病性扩张，不能用于生理年龄测定。只有在淋养循环的早期阶段退化的卵泡才会形成扩张。持续退化的比例（淋营养诊断指数）在每个连续周期中下降。结果表明，研究期间种群的平均年龄为2.04个，比预期少了一个淋养循环，可能是由于该地区宿主稀缺所致。
A study of the age structure of a population of adult female Aedes cantans Meigen was undertaken using the ovarian oil injection technique to determine parity. Results showed that, contrary to popular opinion, ovariolar sacs do not form gonotrophic dilatations and cannot be used for physiological age determination. Dilatations were formed only by follicles which degenerate at a very early stage in the gonotrophic cycle. The proportion which consistently do degenerate (the gonotrophic diagnostic index) decreases in each successive cycle. Results showed that the mean age of the population during the study was 2.04 parous, which was one gonotrophic cycle less than expected, possibly due to scarcity of hosts in the area.
