Adult longevity and lifetime fecundity, but not fertility, of northern (Maine, USA) Wyeomyia smithii (Coquillet) increase with female pupal weight. Mean egg size does not vary with pupal weight, but the standard deviation in egg size shows a marginally significant increase with pupal weight. Egg sizes are not skewed but are leptokurtic in their distribution; neither skewness nor kurtosis changes with female pupal weight. Mean egg size is not correlated with weight-specific adult longevity or with weight- and longevity-specific lifetime fecundity. Reproductive effort early in adult life does not affect longevity, reproductive effort late in life, or reproductive rate late in life. Finally, there is no significant correlation late in adult life between weight-specific rate of egg production and the size of eggs being produced. Egg size does vary within females but is not a variable entered into the physiological allocation of resources among survivorship, fecundity, or rate of egg production.
美国缅因州北部的斯氏伊蚊（Wyeomyia smithii (Coquillet)）成虫的寿命和终生产卵量（而非繁殖力）随雌蛹体重增加而增加。平均卵大小不随蛹体重变化，但卵大小的标准差随蛹体重呈略微显著增加。卵大小分布不呈偏态，但呈尖峰态；偏度和峰度均不随雌蛹体重变化。平均卵大小与体重特定的成虫寿命或与体重和寿命特定的终生产卵量均无相关性。成虫生命早期的繁殖投入不影响寿命、生命后期的繁殖投入或生命后期的繁殖率。最后，成虫生命后期，体重特定的产卵率与所产卵子大小之间无显著相关性。卵大小在雌蚊个体内确实存在差异，但不是影响资源在生存、繁殖力或产卵率之间进行生理分配的变量。
