The polyphagous aphid exhibits host-specific biotypes, notably the cotton (Hap1) and cucumber (Hap3) types. While both can adapt to new hosts via zucchini induction, the underlying molecular mechanisms remain unclear. Our investigation revealed that both Hap1 and Hap3 underwent significant body size enlargement following host transfer to zucchini. Transcriptomic analysis revealed that zucchini-mediated host adaptation in the biotypes (Hap1/Hap3) involves insulin metabolism and detoxification pathways, with 17 co-differentially expressed genes (e.g., (type I collagen), , ) potentially critical for adaptation. The findings provide new insights into the molecular mechanisms regulating phenotypic plasticity and contribute to the development of resistance management strategies.
多食性蚜虫表现出宿主特异性生物型，特别是棉花（Hap1）和黄瓜（Hap3）类型。虽然两者都可以通过西葫芦诱导适应新宿主，但其潜在的分子机制仍不清楚。我们的研究表明，Hap1和Hap3在转移到西葫芦宿主后，体型都显著增大。转录组分析显示，西葫芦介导的生物型（Hap1/Hap3）宿主适应涉及胰岛素代谢和解毒途径，有17个共差异表达基因（如I型胶原蛋白、 、 ）可能对适应至关重要。这些发现为调节表型可塑性的分子机制提供了新见解，并有助于制定抗性管理策略。
