1.许多迁徙动物经历生理和行为变化，以准备和维持长距离运动。由于昆虫迁徙是常见且多样的，因此迫切需要研究迁徙昆虫如何满足长距离迁徙的能量需求。黑脉金斑蝶（Danaus plexippus）每年从北美东部迁徙4000公里到墨西哥中部的越冬地。秋季世代的帝王蝶会因应环境的变化而进行生理和行为上的改变，以开始迁徙。特别是，在初秋暴露于较低的温度和较短的日照长度会导致帝王蝶进入生殖滞育的生殖诱导状态。本研究考察了在秋季样条件下实验饲养的帝王蝶（通常在向南迁移之前经历）相对于在夏季样条件下饲养的帝王蝶的飞行相关代谢率（MR）和飞行性能指标的差异。与夏季条件下饲养的帝王蝶相比，秋季条件下饲养的帝王蝶飞行后MR较低，飞行效率较高，生殖活动较低。飞行后代谢的增加与君主体重，年龄和飞行速度有关。这些发现表明，飞行能量学的跨代转变是帝王蝶复杂迁移综合征的重要组成部分，伴随生殖滞育的生理变化有助于飞行期间的能量保存。
1. Many migratory animals undergo physiological and behavioural changes to prepare for and sustain long‐distance movements. Because insect migrations are common and diverse, studies that examine how migratory insects meet the energetic demands of long‐distance movements are badly needed.2. Monarch butterflies (Danaus plexippus) migrate up to 4000 km annually from eastern North America to wintering sites in central Mexico. Autumn generation monarchs undergo physiological and behavioural changes in response to environmental cues to initiate migration. In particular, exposure to cooler temperatures and shorter day lengths in early autumn causes monarchs to enter the hormonally induced state of reproductive diapause.3. This study examined differences in flight‐associated metabolic rate (MR) and flight performance metrics for monarchs experimentally reared under autumn‐like conditions (typically experienced before the southward migration) relative to monarchs reared under summer‐like conditions.4. Adult monarchs reared under autumn‐like conditions showed lower post‐flight MRs, greater flight efficiency, and lower measures of reproductive activity relative to monarchs reared under summer‐like conditions. Increases in post‐flight metabolism were associated with monarch body weight, age, and flight velocity.5. These findings suggest that a trans‐generational shift in flight energetics is an important component of the monarch's complex migratory syndrome, and that physiological changes that accompany reproductive diapause facilitate energy conservation during flight.
