摘要:
茶树遭受小绿叶蝉等刺吸式害虫危害会严重影响茶叶品质。以自制便携式LED节能诱虫灯为诱捕器,研究不同滤色光波对皖南茶园主要昆虫的诱集效果。试验结果表明,6种滤色光波以金黄色、土黄色和橙黄色光波对植食性害虫的诱集效果较好,其诱集数量分别为469头,410头和403头。以橙红色,土黄色和金黄色光波对天敌昆虫的诱集数量较小,其诱集数量分别为29头,31头和33头,诱集益害比分别为0.09,0.08和0.07。利用金黄色、土黄色和黄绿色3种滤色光波连续诱杀茶小绿叶蝉3晚(每晚诱杀2 h),诱杀结束后11 d茶园茶小绿叶蝉的虫口减退率分别为47.2%、64.8%和57.3%,校正防效分别为72.2%,81.5%和77.5%。茶园灯光诱杀防治小绿叶蝉推荐采用土黄色光源。

Abstract:
Some sucking?mouthparts insect?pests, such as tea leafhopper, could seriously?affect the tea?quality. Using the home-made portable LED energy-efficient trap lamp as a trapping device, the trap effect of several lights produced by color filter on the main insects was researched in tea field of southern region of Anhui province. Result indicated that the three trap lights of the golden-yellow, khaki and orange-yellow showed good trapping effect on the major phytophagous insects, and the number of insect trapped by above lights was 469, 410 and 403 respectively. The trap lights of the orange-red, khaki and golden-yellow showed weak trapping effect on the major natural enemy insects, and the number of natural enemy trapped by above lights was 29, 31 and 33 respectively, and the ratio of?natural enemy?to?insect pest above was 0.09, 0.08 and 0.07, correspondingly. After the trap lights of the golden yellow, khaki and yellow-green were continuously applied to trap tea leafhopper adult in the tea field for three nights (2 hours per night), the reduce?rates of tea leafhopper at 11 days post-treatment were 47.2%, 64.8% and 57.3%, and the control effect against the tea leafhopper were 72.2%, 81.5% and 77.5%, correspondingly. The khaki light was recommended to control tea leafhopper in tea field.
Key words:  tea tree pest  leafhopper  portable energy-efficient trap lamp  khaki color
