is a significant agricultural pest that migrates annually based on the growth stages of its host plants. However, the role of host plant growth stages in the residency or migration of remains unclear. We allowed to feed on maize leaves and seeds, and results showed that maize seeds had higher amino acids, carbohydrates, and triglyceride (TG). that fed on seeds had longer adult stages; larger wings; higher TG, juvenile hormone II (JH II), and JH III; and more developed flight muscles, indicating tendencies toward migration. Interestingly, maize leaves were richer in sterols. that fed on leaves exhibited longer larval stages, higher 20-hydroxyecdysone (20E) and JH I, faster egg maturation, and earlier oviposition, suggesting tendencies toward residency. These findings suggest that the nutritional composition of host plants influences for migration or reproduction, offering new insights into its invasion and establishment patterns.
是一种重要的农业害虫，每年会根据其寄主植物的生长阶段进行迁徙。然而，寄主植物生长阶段在其居留或迁徙中的作用仍不清楚。我们让其取食玉米叶片和种子，结果表明玉米种子含有更高的氨基酸、碳水化合物和甘油三酯（TG）。取食种子的成虫阶段更长；翅膀更大；TG、保幼激素II（JH II）和JH III含量更高；飞行肌肉更发达，表明有迁徙倾向。有趣的是，玉米叶片中的甾醇含量更丰富。取食叶片的幼虫阶段更长，20-羟基蜕皮酮（20E）和JH I含量更高，卵成熟更快，产卵更早，表明有居留倾向。这些发现表明寄主植物的营养成分会影响其迁徙或繁殖的倾向，为其入侵和定殖模式提供了新的见解。
