摘　　要：2018~2020年连续3年在试验地松针萌发前开展5%阿维菌素打孔注药防治松褐天牛,结果表明:松树施药36 240株,存活株数34 660株,平均存活率95.64%,明显高于空白对照平均存活率88.77%;施药后的各类长势松树平均死亡率:长势良好的A类占3.82%;长势一般的B类占4.13%;长势较差的C类占38.29%;防治效果A类优于B类,又明显优于C类;防治成本平均单价45.2元·株。得出用5%阿维菌素打孔注药防治松褐天牛具有可行性和一定的优越性,为防治松褐天牛措施提供一定的参考依据。5% avermectin injection was carried out to control Monochamus alternatus before the pine needle germination in Dangyang City from 2018 to 2020 for three consecutive years.The results showed that 36 240 pine trees were applied with 34 660 survival trees, with an average survival rate of 95.64%,which was significantly higher than the average survival rate of the blank control of 88.77%;the average mortality rate of all kinds of growing pine trees after application of insecticide was 3.82% for class A,4.13% for class B and 38.29% for class C.the control effect on class A was better than that on class B,and was significantly better than that on class C;the average unit price of control cost was 45.2 yuan per plant.Therefore, it can be concluded that it is feasible and advantageous to use 5% avermectin to control M.alternatus,which provides a reference basis for the control measures of M.alternatus.
