摘　　要：为评价金龟子绿僵菌CQMa421对茶角胸叶甲田间防治效果,采用不同剂量组合的2亿孢子/g金龟子绿僵菌CQMa421颗粒剂和80亿孢子/mL金龟子绿僵菌CQMa421可分散油悬浮剂进行了田间试验。结果表明,采用每667 m^2土壤撒施绿僵菌颗粒剂5 kg和绿僵菌油悬剂80 mL连续喷药2次处理方式,对茶角胸叶甲的相对防效可达64.03%,保叶率达46.77%,当季保产效果达58.17%,用金龟子绿僵菌CQMa421防治茶角胸叶甲有较好的应用前景。To evaluate the field control effect of Metarhizium anisopliae CQMa421 on Basilepta melanopus Lefevre,different doses including 200 million spores per gram of CQMa421 granules and 8 billion spores per mL CQMa421 were applied.The field results show that the application of CQMa421 for the prevention of B.melanopus had a great application prospect.The field application of 5 kg M.anisopliae granules per 667 m^2 or spraying 80 mL M.anisopliae for twice reduced the rate of insect population by 64.03%,the rate of leaf preservation by 46.77%,and increased the production by 58.17%.
