The brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is an invasive species to North America and has spread throughout most of the territory. Understanding flight in H. halys is crucial to understanding the dispersal capacity and developing forecasting models for this pest. The purpose of this research was to assess the effects of starvation, age, mating status, sex, and preflight weight on flight parameters of laboratory-reared H. halys using computer-monitored flight mills. The mean flight distance observed over a 24-h period was 266 m and the maximum distance was 7.3 km. Overall, the flight capacity of males and females was similar, even though females weighed more than males. The proportion of H. halys that initiated flight was not affected by starvation, age, or mating status. The number of bouts of individual flights and velocity significantly increased with longer durations of starvation. The number of bouts significantly decreased with increasing age. The total distance flew and total flight time was not affected by starvation, age, or mating status. Although some statistical differences were seen across the experiments, these differences likely represent minimal ecological significance. Therefore, these results suggest that H. halys are remarkably resilient, which may contribute to their success as an invasive species. The findings of this study could help better predict the dispersal potential of H. halys in Minnesota.
黑带红蝽，Halyomorpha halys (Stål)（半翅目：Pentatomidae），是一种入侵北美的物种，已遍布其大部分领土。了解 H. halys 的飞行能力对于理解其扩散能力和开发该害虫的预测模型至关重要。本研究的目的是使用计算机监测飞行测功机评估饥饿、年龄、交配状态、性别和预飞行体重对实验室饲养的 H. halys 飞行参数的影响。在 24 小时内观察到的平均飞行距离为 266 米，最大距离为 7.3 公里。总体而言，雄性和雌性的飞行能力相似，尽管雌性比雄性重。起始飞行的 H. halys 的比例不受饥饿、年龄或交配状态的影响。个体飞行的次数和速度随着饥饿时间的延长显著增加。飞行次数随着年龄的增加而显著减少。飞行总距离和总飞行时间不受饥饿、年龄或交配状态的影响。尽管在实验中观察到一些统计差异，但这些差异可能代表最小的生态意义。因此，这些结果表明 H. halys 具有很强的弹性，这可能有助于它们成为入侵物种的成功。本研究的结果可以帮助更好地预测 H. halys 在明尼苏达州的扩散潜力。
