The tea leafhopper, E mpoasca vitis ( G öthe) ( H emiptera: C icadellidae), is a major pest of the tea plant, C amellia sinensis ( L .) O . K untze ( T heaceae). In this study, the RGB color model was used to describe the colors of sticky traps. The most effective color for attraction of E . vitis was investigated by orthogonal optimization. The selected color was verified in tea gardens and the most effective height for positioning of color sticky traps for capturing tea leafhoppers was investigated. After the determination of the effect of the three color parameters and their interactions by orthogonal optimization, the color gold ( RGB : 255, 215, 0) was selected as the most effective color to trap tea leafhoppers. In tea gardens, more leafhoppers were captured using gold sticky traps ( RGB : 226, 204, 4) than using commercially available yellow sticky traps. The most effective height of gold sticky traps for trapping leafhoppers was 40–60 cm above the tea canopy. Few lady beetles were captured at this height. We conclude that the orthogonal optimization method is a convenient and efficient method to screen digitally generated colors for attracting and trapping of pests.
