Abstract: 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.
