Dendrolimus kikuchii Matsumura is a serious pest damaging Pinus massoniana in high altitude zone in Fujian province. This pest develops two generations a year, overwintering with larvae. The control test showed that the application of the compound biologic pesticide DCPV 5×10 7 PIB/ml + Bacillus thuringiensis 1.6×10 7 spores/ml + Beauveria bassiana 1.2×10 5 spores/ml was effective.
