摘　　要：【目的】探明光周期和LED光源对茄二十八星瓢虫Henosepilachna vigintioctopunctata成虫取食、移动、交配和产卵等行为的影响,为该害虫的预测预报和综合治理提供科学依据和技术指导。【方法】在光期光源为白色日光灯,光照强度约为500 lx, RH 75%±2%条件下观察并记录了30℃时6个不同光周期(16L∶8D, 15L∶9D, 14L∶10D, 13L∶11D, 12L∶12D和11L∶13D)下茄二十八星瓢虫成虫取食、移动、交配和产卵行为;26℃时暗期以不使用光照(12L∶12D)为对照,使用红、黄、蓝、绿和白光5个不同LED光照(分别记为12L∶12R, 12L∶12Y, 12L∶12B, 12L∶12G和12L∶12W)下茄二十八星瓢虫成虫取食、移动、交配和产卵行为。【结果】当光照时长从13 h延长至16 h时,茄二十八星瓢虫成虫取食频次有增加的趋势;当光照时长从12 h延长至15 h时,产卵量有增加的趋势。光周期为14L∶10D和13L∶11D时,成虫取食频次(分别为45.25和25.00次/5对)显著低于其他光周期下,光周期11L∶13D下产卵量(仅有7.25粒/5♀)显著低于其他光周期下。蓝光处理组取食频次(112.50次/5对)显著高于黄光和绿光处理组(分别为77.0和66.25次/5对);黄光和绿光处理组产卵量(分别为261.50和285.50粒/5♀)显著高于对照组。【结论】延长光照时间,茄二十八星瓢虫成虫取食频次和产卵量均有增加趋势;暗期使用蓝光时成虫取食频次增加,而使用黄光和绿光时则产卵量增加。光周期和LED光源对其移动和交配行为影响不显著。【Aim】 This study aims to clarify the effects of photoperiod and LED light on such behaviors as feeding, walking, mating and egg-laying of Henosepilachna vigintioctopunctata adults, so as to provide a scientific basis and technical guidance for forecasting and integrated management of this pest. 【Methods】 Experiments were conducted under the conditions of white fluorescent light intensity about 500 lx in photophase, and RH 75%±2%. The feeding, walking, mating and egg-laying behaviors of H. vigintioctopunctata adults were observed under different photoperiods （16L ∶8D, 15L ∶9D, 14L ∶10D, 13L ∶11D, 12L ∶12D and 11L ∶13D） at 30℃, and under different LED light （red, yellow, blue, green, and white light, represented by 12L ∶12R, 12L ∶12Y, 12L ∶12B, 12L ∶12G, and 12L ∶12W, respectively） with no light （12L ∶12D） as the control in scotophase at 26℃. 【Results】 When the photophase length increased from 13 h to 16 h, the feeding frequency of H. vigintioctopunctata adults increased. When the photophase length increased from 12 h to 15 h, the number of eggs laid also increased. The feeding frequencies in 14L ∶10D and 13L ∶11D groups （45.25 and 25.00 times/5 pairs, respectively） were significantly lower than those in other groups. Significantly fewer eggs were laid in 11L ∶13D group （only 7.25 eggs/5♀） than in other groups. The feeding frequency （112.50 times/5 pairs） in the blue light group in scotophase was significantly higher than those in the yellow and green light groups （77.0 and 66.25 times/5 pairs, respectively）. Significantly more eggs were laid in the yellow and green light groups （261.50 and 285.50 eggs/5♀, respectively） than in the control group. 【Conclusion】 With the increase of photophase, the feeding frequency and number of eggs laid of H. vigintioctopunctata adults increase. Blue light in scotophase can increase the feeding frequency of H. vigintioctopunctata adults, while the yellow and green light lead to the increase in th
