摘　　要：【目的】筛选对铜绿丽金龟和暗黑鳃金龟具有明显诱捕效果的光波波长,研究成虫夜间活动节律,优化金龟成虫的灯诱防控技术。【方法】2014~2015年评价19种不同波长(375~748 nm)LED灯对2种金龟成虫的田间诱捕效果,2019年分时段监测385 nm、395 nm的LED灯以及黑光灯(365 nm±50 nm)的诱捕数量。【结果】2014~2015年,395 nm的LED灯对铜绿丽金龟的诱捕效果显著高于其他18种波长,395 nm的LED灯对暗黑鳃金龟的诱捕数量同样最多,但与418 nm之间差异不显著。2019年385 nm的LED灯诱捕到的铜绿丽金龟、暗黑鳃金龟成虫数量均显著高于395 nm的LED灯,但与黑光灯之间无显著差异。2种金龟成虫的上灯高峰均在20:00~24:00,占整个夜晚(18:00~翌日06:00)诱捕量的68.9%~76.7%。【结论】诱捕铜绿丽金龟和暗黑鳃金龟的最优波长是385 nm,最佳时段为20:00~24:00。【Objective】To screen the light wavelengths with trapping effect on the adults of Anomala corpulenta Motschulsky and Holotrichia parallela Motschulsky,clarify their activity rhythm during night-time,and optimize the lamp-trapping prevention and control technology of these two scarab beetles.【Methods】The field trapping effect of 19 different wavelengths(375-748 nm)LED lights on 2 species of adult scarab beetles was evaluated in 2014 and 2015 andin 2019,the trapping effects of 385 nm,395nm LED lamp and black light lamp on scarabs was compared.At the same time,the night-time rhythm of scarab beetles was studied through experiments.【Result】In 2014 and 2015,the LED lights with 395 nm wavelength had a significantly higher trapping effect on A.corpulenta adults than the lights with other 18 wavelengths.The trapping number of 395 nm LED lights on H.parallela adults was also the highest,but there were no significant difference with that of 418 nm LED lights.In 2019,the trapping number of A.corpulenta adults and H.parallela adults on 385 nm LED lamps was significantly higher than that of 395 nm,but no significant difference was found with that of black light lamps.The trapping peaks of the two scarab beetles were 20:00-24:00,and the trapped amount accounted for 68.9%-76.7%of those during the whole night(18:00-06:00).【Conclusion】The 385 nm LED lamp had the best trapping effect on A.corpulenta adults and H.parallela adults.The peak trapping period of adult was between 20:00 and 24:00.The research results provide an important theoretical basis for lamp trapping prevention and control technology of the two scarab beetles.
