摘要: 【目的】摸清温度、日龄和性别对悬铃木方翅网蝽Corythucha ciliata成虫飞行能力的影响,分析其远距离扩散轨迹。【方法】本研究通过飞行磨系统、高空系留气球和HYSPLIT-4模型相结合的方法测定了悬铃木方翅网蝽飞行能力及模拟其种群随气流远距离扩散轨迹。【结果】飞行磨研究结果表明,随着悬铃木方翅网蝽日龄的增加其飞行距离和飞行时间逐渐增加,10日龄成虫飞行距离和飞行时间最长,随后逐渐下降。不同测试温度(19℃, 22℃, 25℃, 29℃和31℃)下,10日龄成虫飞行距离和飞行时间在19℃时最小,随着温度的升高飞行距离和飞行时间都逐渐增加,在25℃时两者都达到最大,随后逐渐降低,在25℃时的飞行距离显著大于其他测试温度下;28℃时平均飞行速度最快,显著高于其他测试温度下。雌虫在飞行距离和飞行时间上显著高于雄虫。高空系留气球观测结果表明,在5和10 m处悬铃木方翅网蝽种群密度较大,随着高度的上升诱捕数量逐渐下降,在35 m高度处种群数量最低,随后又随着高度的升高诱捕数量逐渐增加,65 m以上高度未能诱捕到试虫。利用HYSPLIT-4模型模拟了2015年悬铃木方翅网蝽由南向北的扩散路线为:河南省郑州市-山西省晋城市陵川县-长治市沁县-沂州市繁峙县-河北省张家口市。【结论】室内悬铃木方翅网蝽成虫在10日龄、25℃温度下飞行能力最强。田间悬铃木方翅网蝽成虫可随气流上升至65 m高度,具备随气流进行低空扩散的能力。

Abstract: 【Aim】 This study aims to investigate the effects of temperature, age and sex on the flight capacity of the alien species Corythucha ciliata, and to analyze its long-distance diffusion trajectory. 【Methods】 The flight capacity of C. ciliata adults and the diffusion trajectory of the population with air flow were measured by using the flight mill system, the high altitude tethered balloon and the HYSPLIT-4 model. 【Results】 The results revealed that the flight distance and flight time of C. ciliata adults were age-dependent, reaching the peak at 10 d after emergence and then decreasing gradually. The flight distance and flight time of 10 day-old adults were the minimum at 19℃ among the test temperatures (19, 22, 25, 29 and 31℃), gradually increased with the increase of temperature, reached the peak at 25℃, and then decreased gradually. The flight distance at 25℃ significantly increased compared with that at the other test temperatures. The average flight speed reached the maximum at 28℃, which was significantly higher than that at the other temperatures. The flight distance and flight time of females were significantly higher than those of males; however, males had significantly higher flight speed than females. The results of the high altitude tethered balloon survey showed that the population density of C. ciliata reached the maximum at 5 and 10 m. With the increase of altitude, the number of insects caught by trap decreased gradually, the population density at 35 m reached the minimum, and no adults were trapped over 65 m. The southern-northern diffusion routes of C. ciliata in 2015 simulated using the HYSPLIT-4 model were from Zhengzhou city, Henan province to Lingchuan county of Jincheng city, and then to Qinxian county of Changzhi city, and then to Fanshi county of Yizhou city, Shanxi province, and finally to the Northeast of Zhangjiakou city, Hebei province.【Conclusion】 In the laboratory the 10 day-old adults of C. ciliata at 25℃ show the strongest flight capacity. In fields C. ciliata adults could rise up to the altitude of 65 m with air flow, and have the ability to diffuse at low altitude with air flow.
