摘要
为探究茶园昆虫对不同颜色的偏嗜性差异,解决现有诱虫板选择性差等问题,本研究利用印刷色彩模式(CMYK)调色技术制备了25种不同颜色的诱虫板,对茶园昆虫进行了诱集试验.结果表明,韭黄色(C20M0Y70B0)对茶园叶蝉科昆虫诱集效果最好,诱杀量达到390.0头/板;绿色(C100M0Y100B0)对盾蚧科昆虫诱集效果最好,诱杀量为275.3头/板;紫色(C20M80Y0B0)对茶园蓟马诱集效果最好,诱杀量为107.0头/板.诱杀结果与生产中广泛使用的黄板和蓝板均具有显著差异.不同颜色的诱虫板对天敌昆虫也有不同引诱效果,其中,淡青色(C20M0Y20B0)、品红色(C0M100Y0B0)对肿腿蜂科和姬蜂科天敌影响较大;肉黄色(C0M20Y60B0)对草蛉影响较大.研究结果表明,茶园害虫对颜色均具有偏嗜性,而准确的颜色配比能针对昆虫的色彩偏嗜性开发出更匹配的诱虫板,以便发挥诱虫板的最大效益.本研究为诱虫板精细化应用、高效防控茶园害虫提供了理论依据.
In order to provide a theoretical basis for the fine application of insect trap boards and the effective control of tea garden pests,this experiment used the printing color mode(CMYK)toning technology to prepare 25 different color boards to trap insects in tea gardens.The results showed that trap boards of leek yellow(C20M0Y70B0),green(C100M0Y100B0)and purple(C20M80Y0B0)had the best trapping effect on Cicadellidae,Diaspididae and tea garden thrips in the tea garden,with a trapping amount of 390.0,275.3 and 107.0 head/board,respectively.The results were significantly different from those of yellow board and blue board which are currently used widely in production.Insect traps of different colors also had different attracting effects on natural enemy insects.Of the 25 different color traps tested,light blue(C20M0Y20B0)and magenta(C0M100Y0B0)had great effects on the natural enemy insects of Bethylidae and Ichneumonidae and Flesh yellow(C0M20Y60B0)had a greater effect on lacewing.The above results showed that different pests in tea gardens had a preference for color,and proper color matching could develop a better matching insect trap for this color preference of insects and maximize the benefits of the insect traps.
