This study presents a novel strategy for regulating caste ratio via maternal reproduction in a parthenogenetic social aphid, Pseudoregma bambucicola. Most mothers in the colony produce only soldiers or normal nymphs, whereas a small proportion of mothers can produce both castes. Changes in the expression of key genes, including those related to reproduction, fertility, and chemical communication, may be responsible for the differentiation in maternal reproduction and caste development.
本研究提出了一种通过孤雌生殖社会性蚜虫竹蚜的母性生殖来调节级型比例的新策略。群体中大多数母体能产生的后代只有兵蚁或正常若虫，而一小部分母体能同时产生这两种级型。关键基因表达的变化，包括与生殖、生育力和化学通讯相关的基因，可能是导致母性生殖和级型发育分化的原因。
