摘　　要：茶树害虫是影响茶叶产量及品质的一个重要因素。采用灯光诱集法,研究了12种频振光源对皖南丘陵茶园主要昆虫的诱集效果。结果表明,5#、6#、3#和9#光源对植食性昆虫的诱集效果较好,其诱集数量分别为1719头、1 467头、1 223头和1 155头。6#、3#、8#和4#光源对天敌昆虫的杀伤作用较大,其诱集数量分别为100头、99头、81头和76头。皖南丘陵茶园主要害虫灯诱防治推荐采用5#(光谱范围295～490 nm,峰值350 nm)和9#(光谱范围300～390 nm,400～505 nm,峰值348 nm,452 nm)频振光源,其田间诱集益害比均为0.04,既能有效诱杀主要茶树害虫,又能最大限度地保护天敌昆虫。Tea pest is an important factor affecting the yield and quality of tea. Trapping effect of 12 light sources from frequency trembler grid lamp on major insect was tested in hilly tea fields of southern Anhui. The re- suits indicated that the major phytophagous insects trapped by light sources of number 5, 6, 3 and 9 were relatively abundant, and the number of the phytophagous insects accumulated was 1 719, 1 467, 1 223 and 1 155, respectively. Light sources of number 6, 3, 8 and 4 showed more trapping effect on the natural enemy, and the number of population trapped by above four light sources was 100, 97, 81 and 76, correspondingly. Light sources of number 5 （Spectral range： 295-490 urn; Peak value： 350 nm） and 9 （Spectral range： 300-390,400-505 nm; Peak value： 348, 452 nm） were the optimized trapping light sources, and the ratio of natural enemy to insect pest both was 0.04. The two optimized light sources could trap more major insect pests and well protect natural enemies in tea garden.
