摘　　要：利用粉虱座壳孢,以喷菌法防治油茶黑刺粉虱,结果表明:以(1±0.5)×10 6个/m L的孢悬液进行喷菌,1个月后,茶黑刺粉虱感染率73.47%,防治效果为71.76%,3个月后,感染率66.63%,防治效果为58.56%,1年后,还有32.16%的持续防治效果,该种防治方法在生产中有应用前景。Using Aschersonia aleyrodis Webb. to prevent Aleurocanthus spiniferus（Quaintanca） with spraying spore solution, the results showed that the infection rate and the control effect were 73.47% and 71.76%, respectively, with（1±0.5）×10 6 spores/m L for a month. And then they were 66.63% and 58.56%, respectively, after treatment for three months. For one year, the sustainable control effect of A.aleyrodis on A.spiniferus was still 32.16%. Therefore, this method has application prospects in production.
