黄板诱杀茶园黑刺粉虱及假眼小绿叶蝉效果及特性研究

采用黄板诱杀茶黑刺粉虱和假眼小绿叶蝉,试验结果表明防治效果明显,诱杀区黑刺粉虱和假眼小绿叶蝉虫口平均校正减退率分别达到71.92%和53.73%,黄板表面所粘附的害虫具有规律性分布特征,即黄板离茶蓬越近的部位诱杀虫数越多,黄板两侧诱杀的虫数多于中部。因此,建议在茶园中使用黄板防治黑刺粉虱和假眼小绿叶蝉时黄板下缘应尽量靠近茶蓬,并根据茶蓬宽度,采用高20~25 cm,宽35~45 cm规格的黄板,可提高其诱杀效果,降低防治成本。

Study on the Effect and Characters of Yellow Sticky Trap Sticking Aleurocanthus spiniferus and Empoasca vitis Gothe in Tea Garden

The significant effects using yellow sticky trap for trapping Aleurocanthus spiniferus and Empoasca vitis (Gothe) were observed. The results showed that the declining rate of vermin population reached 71.92 % and 53.73 %,respectively. And the vermin stuck on surface of the yellow sticky trap had the regular distribution characteristics, namely the trapped vermins closer to the tree crown were more,and the trapped vermins in the edge were more than that in the middle. It was suggested that the yellow sticky trap should used as closer as possible to the tree crown, and in accordance with the width of tree crown of the tea plant, as height 20-25 cm, width 35- 45 cm for sticking Aleurocanthus spiniferus and Empoasca vitis (Gothe) in the tea garden,which could enhance the effectiveness of trapping, and reduce the costs of prevention and treatment.
