摘　　要：研究BtA对茶园重要害虫茶小绿叶蝉和蚜虫的田间控制效果,评估BtA对天敌昆虫草间小黑蛛数量的影响及在茶叶、土壤中的消解动态,结果表明:BtA对小绿叶蝉和蚜虫的控制效果与高效氯氰菊酯相当,对天敌昆虫的毒性较低。BtA施用14 d后在茶叶和土壤中可以完全消解,是一种高效、低毒、低残留的生物杀虫剂,可以在茶园害虫防治中大面积推广应用。In this study, the field control effect of BtA on green leafhopper and aphid was investigated, and its effect on the population of Erigonidium graminicolum（Sundevall） amount in tea garden plantation, as well as the degradation dynamics in tea and soil were evaluated. The results showed that the control efficiency of BtA on green leafhopper （Empoasca vitis） and aphid was similar as that of beta-cypermethrin, and had low toxicity to Erigonidium graminicolum （Sundevall）. BtA could be totally degraded in tea and soil after 14 days. Our research indicates that BtA is an effective biological insecticide with low- toxicity and low - residue, andcould be widely used in pests control of tea garden.
