应用粉虱座壳孢防治茶黑刺粉虱试验研究

摘要

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)×106 spores/mL 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.%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)×106个/mL 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。
