摘　　要：In the paper, the ultra-low-volume spraying of oil formulation of Beauveria bassiana was used to control Dendrolimus punctatus. The results indoor and outdoor showed that conidial powder of B. bassiana had a good control effect on D.punctatus with mortality of more than 80%, and started appearing white cadaver on the sixth day after spraying with concentrations of 200*!mL·(667*!m 2) -1 and the mortality reached 70.9% on the seventh day. Adding Femalerate in oil formulation had a significant addition toxicity effect, and the more the density of Fenvalerate,the more is the mortality of D.punctatus, and they attained death peak on the fifth day after spraying with Femalerate of 0.4*!mL·(667*!m 2) -1, and mortality attained 96.1% after fifteen days. There were the most droplet at a spraying distance of 4*!m, and effective spray width was from 2*!m to 6*!m with mortality of more than 85%, and mortality of pests were positively relative with quantities of droplet.In the paper, the ultra-low-volume spraying of oil formulation of Beauveria bassiana was used to control Dendrolimus punctatus.
