摘要/Abstract

摘要： 研究茶丛距频振式诱虫灯和路边的距离与茶天牛(Aeolesthes induta Newman)幼虫危害程度的关系,以确定诱虫灯控制茶天牛危害的效果。以浙江苍南五凤香茗茶园为例,调查距诱虫灯约0～120 m半径范围、距路边约0～250 m的茶丛被茶天牛幼虫危害程度。结果表明,距诱虫灯约5 m以内的茶丛平均被害率(9.0%)显著低于距灯约20～50 m处的平均被害率(17.5%)；距茶园路边约50 m以内的茶丛受茶天牛幼虫危害较远离路边的重,平均被害率20.0%以上；远离路边约70 m以外,茶丛受害较轻,被害率小于10.0%；茶丛距诱虫灯距离超出约20 m、距路边约50 m以内,茶丛被害率近30%。频振式诱虫灯控制茶天牛危害的效果受双重距离因素影响,其中茶丛距路边的距离是主要影响因子。诱虫灯可以将距路边70 m以外、5 m半径内茶丛的茶天牛幼虫危害控制在10.0%以内。

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．
