选择不同颜色的色板对棉田中大青叶蝉进行诱集筛选试验,并对放置高度、放置位点、朝向和不同时段进行技术优化试验.结果表明,黄板诱集效果最佳;高度和朝向对诱集效果不存在显著影响;但放置位点和时段对诱集效果存在显著影响,色板在棉田中央或距离田边1 m处和19:00~7:00时诱集效果最佳.本研究对色板田间使用技术进行优化,为棉田大青叶蝉的综合防治奠定理论基础.%Effectiveness of color of the board, and hanging height, location, facing direction, and time of day in setting the traps for attracting leafhoppers,Cicadella viridis, in a cotton field was studied.It was found that yellow captured significant more of the adult insects than other colors.The height and orientation in hanging the traps did not alter the color preference of the insects.More leafhoppers were caught in the yellow traps placed 1 m from edges or at the center of the field than those placed on the ridge between two fields.Most adult leafhoppers were captured between the hours of 19:00 to 07:00 in a day.The results obtained would be useful for the establishment of an integrated management program on the cotton fields for the pest control.
