摘　　要：【目的】探明LED光源对柳圆叶甲Plagiodera versicolora（Laicharting）成虫行为的影响，为城市亮化工程中害虫的预测预报或干扰其行为、控制其为害提供参考依据。【方法】在实验室条件下观察了6种LED光源（红光620～625nm、黄光580～585nm、蓝光465～467nm、绿光520～523nm、白光460～465nm和频闪）下柳圆叶甲成虫的行为。【结果】（1）在4d的节律行为观察中，雌或雄成虫不同光处理下暗时相活动频率差异均不显著，但在12h暗期：12h光期和12h白光：12h光期处理下雌成虫活动高峰在中午、12h黄光：12h光期和12h绿光：12h光期下均在18：00--19：00、其余处理下均在上午；12h黄光：12h光期和12h蓝光：12h光期处理下雄成虫活动高峰分别是18：00--19：00和08：00-09：00，其余活动高峰均在11：00-12：00；同一光照条件下，雌雄成虫在暗时相的活动频率差异均不显著。（2）在3h的连续行为观察中，雌成虫各行为发生率在不同光处理问差异不显著，而雄成虫的爬行、休息和展翅发生率在不同光处理间则有显著差异；同一光照条件下，雌或雄成虫爬行和休息行为发生率高于其他行为发生率。雌虫以白光下休息时间分配率最高、绿光下最低；雄虫以绿光下爬行时间分配率最低、黄光下休息时间分配率最高；同一光照条件下的同一种行为发生率和时间分配在两性问也有差异。【结论】LED光源对柳圆叶甲成虫行为有影响，但因LED光源颜色（波段）及性别、自身行为种类不同而异。[Objectives] To investigate the effects of different light-emitting diode （LED） sources on the behavior of adult Plagiodera versicolora （Laieharting） and thereby assess the potential of using this technology to predict the damage caused by this pest and disrupt its behaviour. [Methods] The circadian behavioral rhythm of P versicolora was monitored for four days and their behavior observed continuously for three hours under six different LED sources （red, 620-625 nm; yellow, 580-585 nm; blue, 465-467 nm; green, 520-523 nm; white, 460-465 nm and flashing LED source） under standard laboratory conditions. [Results] （1） There were insignificant differences in the circadian behavioral rhythms of female or male adults during the dark phase of different light treatments. Peak activity of female adults under a 12 h dark ： 12 h light and 12 h white ： 12 h light treatment occurred at noon, whereas peak activity of those under a 12 h yellow ： 12 h light and 12 h green ： 12 h light treatments occurred between 18：00-19：00. Peak activity of those under other light regimes occurred in the morning. Peak activity of male adults under a 12 h yellow ： 12 h light and 12 h blue ： 12 h light treatment regime occurred between 18：00-19：00 and 08：00-09：00, respectively, and that those under other light regimes occurred between 11：00-12：00. There were insignificant differences in activity frequency in the dark phase between females and males under the same light regime. （2） There were insignificant differences in the frequencies of various behaviors among females subject to different light treatments for three hours. However, there was a significant difference in the amount of time spent walking, resting, or wing-spreading among males under different light treatments. Under the same light regime, walking or resting were more frequent than other behaviors in both females and males. For female adults, the rate of resting was highest under white light and lowest under green light. However, for m
