不同药剂对茶毛虫的防治效果研究

Study on Control Effect of Different Pesticides on Euproctis pseudoconspersa Strand

[目的]选择防治有机茶园茶毛虫的有效药剂。[方法]选择3种生物农药和1种化学农药进行茶毛虫防治效果筛选试验。[结果]化学农药10%联苯菊酯乳油对茶毛虫的防治效果最好,见效最快;生物农药16 000 IU/mg苏云金杆菌可湿性粉剂和0.3%苦参碱水剂对茶毛虫也具有较好的防治效果;0.3%印楝素乳油的防治效果相对较差。[结论]建议在有机茶生产中使用生物农药防治茶毛虫,采取几种药剂交替轮换使用。

[Ohjective]The aim of this study was to choose the efl＇ective pesti- cides to control Euproctis pseudocon- spersa in organic tea garden. [Method] The screening test for controlling Eu- proctis pseudoconspersa was conducted by using three biological pesticides and one chemical pesticide. [Resuh] 10% bifenthrin EC had the best and fastest control effect on Euprocti~ pseudocon- spersa. 16 000 IU/mg Bt WP and 0.3% matrine AS had better eontroi effect on Euproctis pseudoconspersn. The control effeet of 0.3% azadiraehtin EC was the worst.[Conclusion] It is suggested that biological pesticides be used alternative- ly to control Euproctis pseudoconspersa in organic tea production.
