Color sticky cards are extensively used to trap or monitor pests. One obvious disadvantage of color sticky cards is that a lot of non-target insects are also trapped. To ameliorate this problem, we investigated the influence of different components of color sticky cards in tea gardens. Specifically, we examined the effects of substrate pattern design, glue thickness, and auxiliary volatiles on the number of captured target pests, Empoasca onukii, a serious pest of tea plants, and major beneficial arthropods. Field results showed that some colors were repellent to beneficial arthropods. Therefore, we designed a bicolor pattern that combined an attractive color (gold, RGB: 255, 215, 0) with a repellent color (red, RGB: 255, 0, 0) to significantly decrease the number of beneficial arthropods captured on color sticky cards without affecting the number of captured target pests. The pattern shape had no impact on effectiveness, but more target pests and beneficial arthropods were captured when the proportion of the attractive color or the glue thickness increased. A suitable attractive color proportion (50 %) and glue thickness (0.4 mm) can help reduce the number of captured beneficial arthropods. As an auxiliary measure, the effect of volatile compounds was significant but complicated, and satisfactory volatiles were difficult to identify. The effectiveness of a bicolor pattern design would vary by target pest and community composition. Nevertheless, this method could become an important component of pest trapping if color traps are redesigned to reduce unintended impacts on beneficial arthropods.

彩色粘卡广泛用于诱捕或监控害虫。彩色粘卡的一个明显缺点是，很多非目标昆虫也被困住了。为了改善这个问题，我们研究了茶园中彩色粘卡的不同成分的影响。具体而言，我们研究了基材图案设计、胶水厚度和辅助挥发物对捕获的目标害虫Empoasca onukii数量的影响，一种严重的茶树害虫，也是主要的有益节肢动物。现场结果表明，一些颜色对有益的节肢动物有排斥作用。因此，我们设计了一种双色图案，将吸引人的颜色（金色，RGB：255, 215, 0）与排斥色（红色，RGB：255, 0, 0）相结合，以显着减少在颜色粘性上捕获的有益节肢动物的数量卡而不影响捕获的目标害虫的数量。花纹形状对有效性没有影响，但当诱人颜色的比例或胶水厚度增加时，捕获更多的目标害虫和有益节肢动物。合适的有吸引力的颜色比例 (50%) 和胶水厚度 (0.4 毫米) 可以帮助减少捕获的有益节肢动物的数量。作为辅助措施，挥发性化合物的作用显着但复杂，并且难以鉴定令人满意的挥发物。双色图案设计的有效性因目标害虫和群落组成而异。尽管如此，如果重新设计颜色陷阱以减少对有益节肢动物的意外影响，这种方法可能成为害虫诱捕的重要组成部分。
