不同颜色粘虫板对北方茶园昆虫的诱集效果评价OA

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.
