摘要
枸杞蛀果蛾(Scrobipalpa erichiodes Bidzilya et Li)是枸杞的重要害虫,以幼虫钻蛀枸杞花蕾或果实为害。由于幼虫为害过程和栖息场所隐蔽,仅成虫期暴露,化学防治困难。作者采用便携悬挂式太阳能光控型诱虫试验装置,研究红色、橙色、黄色、绿色、青色、蓝色、紫色7种不同波段LED光源对枸杞蛀果蛾的诱集效果,并利用诱捕效果高的紫色光源灯具监测种群发生动态。结果表明,紫色光源灯具诱捕效果显著好于其他6种光源;与紫色光源波长接近的青色和蓝色也有一定的诱捕效果,但远不及紫色光源。紫色是枸杞蛀果蛾的敏感光源。枸杞蛀果蛾2022年越冬代羽出高峰期在4月下旬,诱虫量高;6月初出现第2个高峰,但虫量较小。
Scrobipalpa erichiodes Bidzilya et Li is a major pest on Lycium barbarum,which damages the flower buds or fruits of Lycium barbarum with larvae.The insects are only exposed during the adult stage,making chemical control difficult.Portable suspended solar light traps were used and studied the phototaxis of adult moths by inserting seven different wavelength Led light sources:red,orange,yellow,green,cyan,blue and purple.Then purple light sources with high trapping effects were used for monitoring of insect population dynamics.The results showed that the trapping effect of purple light source lamps is significantly better than the other six light sources;Cyan and blue,which have wavelengths similar to those of purple light sources,also have a certain trapping effect,but are far less effective than purple light sources.Purple is a sensitive light source for goji berry fruit moth.The peak period for the overwintering and feather emergence of goji berry fruit moth in 2022 is in late April,with a high amount of insect attraction;The second peak appeared in early June,but the insect population was relatively small.
