在20 °C、18 L：6D ~ 10 L：14 D的光周期条件下，对豌豆蚜Acyrthosiphon pisum（Harris）无性系有性和无性型的产生进行了研究。在长时间的繁殖过程中，只产生胎生子。在中间世代，最老的后代是雌性，而最年轻的后代是雄性。在这两组的生产之间有1至2天的停顿。雌性仅产生3-4天，而雄性约产生12天。在较长的中间间期，雌性为胎生，而在较短的中间间期，雌性为卵生。在两种雌性变体都存在的家庭中，胎生子最先出生。在最短的生育期，家庭完全由女性组成，卵生在前半期，胎生在后半期。讨论了这些序列的生态学意义。
Production of sexual and asexual morphs of a clone of the pea aphid, Acyrthosiphon pisum (Harris), was monitored under photoperiods ranging from 18L:6D to 10L:14D at 20 °C. Under long photophases only viviparae were produced. At intermediate photophases families were produced in which the oldest progeny were females while the youngest progeny were males. A 1- to 2-day pause intervened between the production of these two groups. Females were produced only for 3–4 days while males were produced for about 12 days. At longer intermediate photophases the females were viviparae while at shorter intermediate photophases they were oviparae. In families containing both female morphs, viviparae were born first. At the shortest photophases, families consisted entirely of females, oviparae being produced in the first half and viviparae in the second half of the reproductive period. The ecological significance of these sequences is discussed.
