茶天牛（Aeolesthes induta Newman）发生危害严重影响茶树寿命和茶叶产量,如何高效地防治茶天牛已成为近年来有机茶园亟待解决的问题。本研究选择糖醋酒液、白糖和蜂蜜为食诱剂成分,筛选出蜂蜜20倍稀释液最适合用于诱集茶天牛成虫,高峰期每7βd的平均诱虫量可达（60.3±15）头,且雌虫数量是雄虫的2倍;应用技术研究结果显示,添加农药对搭配水盆诱捕器的食诱剂无显著增效作用,诱捕器的悬挂高度以平行或高于茶棚30βcm为宜,雨天食诱剂对天牛成虫的日诱集量会下降86%以上。本研究筛选出的食诱剂效果显著、成本低、使用方便,可用于今后茶园茶天牛的监测和防治。
The health and yield of tea trees will be seriously damaged by the longicorn beetle, Aeolesthes induta. In recently years, the effective control of A. induta in organic tea gardens had already been a serious problem. In this study, a suitable food attractant has been screened from sugar-acetic acid-ethanol, sugar and honey. The results showed that 20 times dilution of honey could attract longicorn beetles effectively, and the mean captures reached 60.3±15 per week during the outbreaks of A. induta. The number of trapped females was double that of males. Moreover, the application of this food attractant was studied. Pesticide addition was unnecessary for the food attractant combined with the water basin traps. The suitable hanging height of traps was parallel to or 30βcm above the tea canopy. Compared with the captures in the sunny days, the number of the trapped A. induta per day would drop more than 86 per cents in the rainy day. The screed honey food attractant had significant effects, low costs, and convenient usages, and should be an important technique for controlling and monitoring A. induta in tea gardens.
