进行了两种类型的小尺度选择实验。(1)进行了不同年龄雌虫繁殖力的人工选择实验。选择早繁殖力超过三代产生了统计上可检测的直接反应。其他生活史性状未见间接反应。晚育超过三代的选择没有产生任何可检测到的直接反应。间接反应：早期产卵减少，寿命增加。(2)自然选择对晚期适应性成分的影响增加了晚期繁殖力、延长了雌性寿命、延长了雌性繁殖时间，而降低了早期繁殖力和平均产卵率。
two types of small-scale selection experiments were performed. (1) Artificial selection experiments were performed on age-specific female fecundity. Selection for early fecundity over three generations produced a statistically detectable direct response. There was no detectable indirect response in other life-history characters. Selection for late fecundity over three generations did not produce any detectable direct response. Indirect responses were detected: early egg-laying decreased and longevity increased. (2) Natural selection for late-age fitness components increased late fecundity, female longevity, and the duration of female reproduction, while early fecundity and mean egg-laying rate decreased.
