1.豌豆蚜虫（Acyrthosiphon pisum）是由一系列宿主植物相关种群组成的分类单元，被广泛用作探索生态物种形成和专门化进化的模型系统。因此，了解母体和成年前的经历如何影响该物种对寄主植物的利用是很重要的。以3个草地山豌豆蚜虫无性系为材料，研究了母株和成虫前期寄主植物对蚜虫成虫生殖力和寄主选择性的相对重要性.母株对子代生殖力无显著影响.蚜虫生长的寄主植物影响成虫的生殖力，尽管是以一种复杂的方式，既取决于成虫的寄主植物种类，也取决于转移到试验植物后的生殖力.所有三个无性系都更喜欢在山豌豆上定殖，并且这种偏好对于在山豌豆上饲养的蚜虫更强。这一结果对研究利用A。pisum进行了讨论。
1. The taxon known as the pea aphid, Acyrthosiphon pisum, is composed of a series of host plant associated populations and is widely used as a model system to explore ecological speciation and the evolution of specialisation. It is thus important to know how maternal and pre-adult experience influences host plant utilisation in this species.2. The relative importance of the maternal and pre-adult host plant for adult fecundity and host preference was investigated using three aphid clones collected from Lathyrus pratensis and maintained on Lathyrus or Vicia faba.3. No significant effects of the maternal host plant on offspring fecundity were detected.4. The host plant on which the aphid grew up influenced adult fecundity, although in a complex way that depended on both the adult host plant species and when after transfer to the test plant fecundity was assessed.5. All three clones preferred to colonise Lathyrus over Vicia, and this preference was stronger for aphids raised on Lathyrus.6. The significance of the results for studies of the evolution of specialisation and speciation that employ A. pisum is discussed.
