不同颜色色板对茶角胸叶甲成虫田间诱集效果研究

摘要

为了比较评价不同颜色色板对茶角胸叶甲成虫诱虫效果,指导田间色板诱虫.采用4种不同颜色的色板研究茶角胸叶甲成虫的田间的诱虫效果,并进行了3个悬挂高度色板对该虫的诱集试验.结果表明:白色和黄色色板诱集到的茶角胸叶甲成虫数量高于蓝色色板和绿色色板;在置于茶丛下紧挨地面处4种颜色色板的诱集成虫数量也明显高于茶面平行处和茶面以上30cm处.因此,建议用白色和黄色色板监测和治理茶角胸叶甲成虫发生,高度以茶丛下紧挨地面处位置为宜.%In order to compare the response of Basileptamelanopus Lefevre to different colors and provide new guide for field trapping, sticky cards of 4 different colors and 3 hanging heights were used to study the taxis of the adults of Basileptamelanopusin the field. The results appeared that the number of fruit fly adults trapped by the white and yellow cards was significant higher than those trapped by blue and green cards. The hanging height test results indicated that the number of fruit fly adults trapped by sticky cards Close to the ground at the tea bushes was significantly higher than those at punta tea and upper 30 cm height of punta tea. Thus, the white and yellow cards were suggested to be used to monitor Basileptamelanopus adult population dynamics, and the optimum height was the close to the ground at the tea bushes.
