Abstract: Cangnan County is one of important tea\|producing areas in Zhejiang Province. The investigation for the damage characteristics of tea longhorn beetle (Aeolesthes induta Newman) was carried out in Wufeng organic tea garden in Cangnan County. The results showed that the damage rate of tea longhorn beetle was about 6.7%-50.0%. Moreover, the damage characteristics of tea longhorn beetle were as follows: the damage occurred near hilltop (altitude 450 m)was more serious than that on the halfway hill (altitude 350 m);the damage occurred in the north side of road was more serious than that in the south side; the damage occurred at about 1 m away from roadside was more serious than that at 100 m away from the roadside. In all, the damage degree of tea longhorn beetle might be influenced by the depth of soil layer, root exposure, trapping light and so on.
