Abstract: To determine the effect of frequency\|vibration trap lamp (FTL) on controlling TLB, tea longhorn beetle (Aeolesthes induta Newman), a case study was carried out on the relationship between TLB larvae damage degree and the distances of tea clumps to trap lamp (about 0-120 m) and to road side (about 0-250 m) in a tea garden in Cangnan County, Zhejiang Province. The result showed that 9.0% tea clumps, about 5 m close to FTL was damaged by TLB larvae, which was significantly lower than that (17.5%) of tea clumps about 20－50 m away from trap lamp; the clumps, about 50 m near to road side, was damaged by TLB larvae more seriously than that of far away from the road, the average injured rate was more than 20.0%; the clumps about 70 m away from road side was damaged lightly, the injured rate was less than 10.0%; approximately 30% injured rate was observed in the tea clumps where about 20 m farther away from trap lamp and about 50 m nearer to road side. The effect of FTL on controlling TLB was affected by two kinds of distances, in which the distance of tea clump to road side was major impact factor. FTL could control the damage of TLB larvae down to 10.0% where the clumps were 70 m farther away from road side and 5 m nearer to FTL．

Key words: tea longhorn beetle (Aeolesthes induta) larvae, frequent\|vibration trap lamp, tea clump
