不同颜色粘虫板对北方茶园昆虫的诱集效果评价

Evaluation of the Trapping Effect of Sticky Insect Boards of Different Colors on Insects in Northern Tea Gardens

摘要

粘虫板是茶园广泛使用的物理防治工具，由于茶园害虫种类繁多，单一颜色粘虫板对天敌昆虫群落容易造成误杀，破坏茶园生态系统。为解决此问题，本试验探索多种有效颜色色板结合使用。采用RGB配色法，设置16种不同颜色的粘虫板，在6月、10月进行害虫和非靶标昆虫的诱集试验，评价不同颜色诱虫板对北方茶园主要害虫以及非靶标昆虫的引诱效果。结果表明，不同颜色粘虫板对北方茶园主要害虫及天敌的诱集效果差异极显著：黄色（255/255/0）对多数昆虫都有较强的诱集性，但在使用中对天敌类昆虫有一定的威胁；深红色（200/8/82）及橙色（234/85/32）对绿盲蝽诱集性较强；土黄色（135/143/0）对小贯小绿叶蝉的诱集效果最好。不同粘虫板在6月与10月的诱集量和诱集益害比都有所波动：黄色色板诱集量下降；土黄色色板益害比由0.037提升至0.143。根据试验结果得出颜色分组：黄色因高诱虫数目单独分为一类，红色与土黄色诱虫效果相似分为一类，深红色和橙色因色彩与绿盲蝽寄主颜色相似并入同一类。本试验通过量化北方茶园色板诱杀技术的生态权衡效应，为北方生态茶园不同时期使用不同颜色粘虫板组合进行更有效的物理防控提供参考。

Abstract

Sticky boards are widely used physical control tools in tea gardens. However, due to the diversity of pest species, single-colored sticky boards may inadvertently harm natural enemy communities and disrupt the plantation ecosystem. To address this issue, this experiment explores the combined use of multiple effective colored boards. Using the RGB color matching method, it sets up 16 different-colored sticky boards, and conducts pest and non-target insect trapping trials in June and October to evaluate the trapping efficacy of different colored boards against major pests and non-target insects in northern tea gardens. The results show significant differences in the trapping effects of different colored sticky boards on major pests and natural enemies in northern tea gardens: yellow (255/255/0) exhibits strong attractiveness to most insects but poses a certain threat to natural enemy insects during use; ruby (200/8/82) and orange (234/85/32) show strong trapping efficacy for green leafhoppers; ochre (135/143/0) demonstrates the best trapping effect on Empoasca onukii. The trapping quantities and beneficial-to-harmful ratios of different sticky boards fluctuates between June and October: the trapping quantity of yellow boards decreases, while the beneficial-to-harmful ratio of ochre boards increases from 0.037 to 0.143. Based on the experimental results, the colors are categorized as follows: yellow is classified separately due to its high insect-trapping efficiency; red and ochre are grouped together due to their similar trapping effects; ruby and orange are merged into the same category because their hues resemble the host plant colors of green leafhoppers. By quantifying the ecological trade-offs of colored board trapping technology in northern tea gardens, this study provides a reference for more effective physical control of pests using different combinations of colored sticky boards during various periods in northern ecological tea gardens.
