The recent emergence of Xylella fastidiosa in Europe is a major threat to agriculture, including olive, almond and grape. Philaenus spumarius is the predominant vector of X. fastidiosa in Europe. Understanding vector movement is critical for developing effective control measures against bacterial spread. In this study, our goal was to set up a flight-mill protocol to assess P. spumarius flight potential and to analyse how different variables may affect its flight behaviour. We found that P. spumarius was able to fly ≈ 500 m in 30 min with a maximum single flight of 5.5 km in 5.4 h. Based on the observations, the flight potential of the females was higher in spring and autumn than in summer, and that of the males was highest in autumn. Moreover, we found that P. spumarius had a higher flight potential during the morning and the night than during the afternoon. Our results revealed that P. spumarius is likely to disperse much further than the established sizes of the infected and buffer zones designated by the EU. This knowledge on the flight potential of P. spumarius will be critical for improving management actions against P. spumarius and the spread of X. fastidiosa in Europe.
韧皮部难养菌在欧洲的新近出现对农业构成了重大威胁，包括橄榄、杏仁和葡萄。烟盲蝽是欧洲韧皮部难养菌的主要传播媒介。了解媒介的移动情况对于制定针对细菌传播的有效控制措施至关重要。在这项研究中，我们的目标是建立飞行磨协议来评估烟盲蝽的飞行能力，并分析不同变量如何影响其飞行行为。我们发现，烟盲蝽在 30 分钟内能够飞行 ≈ 500 米，在 5.4 小时内最大单次飞行距离为 5.5 公里。根据观察结果，雌性烟盲蝽在春季和秋季的飞行能力高于夏季，而雄性烟盲蝽在秋季的飞行能力最高。此外，我们发现烟盲蝽在早晨和夜间的飞行能力高于下午。我们的研究结果表明，烟盲蝽的扩散范围可能比欧盟指定的感染区和缓冲区的现有面积大得多。了解烟盲蝽的飞行能力对于改善针对烟盲蝽和欧洲韧皮部难养菌传播的管理措施至关重要。
