Abstract: 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.
