云南大叶种茶园中?小绿叶蝉和蜘蛛的数量动态研究

Quantitative Dynamics of Empoasca onukii(Matsuda) and Araneida in Different Large Leaf Tea Plantations in Yunnan

通过调查云瑰、云抗10号、云抗14号3类茶园的小绿叶蝉、蜘蛛数量的种群变化,探讨正常人工管理和自然生长2种处理方式对茶园中小绿叶蝉和蜘蛛数量的影响。初步认为,3个茶树品种对小绿叶蝉的抗性没有明显差异,蜘蛛在云瑰中的数量显著小于云抗10号和云抗14号;采茶、耕作等人工操作和喷施生物农药能显著控制小绿叶蝉的数量,而对蜘蛛数量的影响有限,夏季需要加大对小绿叶蝉的防控。

Through the investigation on the population changes of Empoasca onukii(Matsuda)and Araneida in three types of tea plantations planted with Yungui,Yunkang 10 and Yunkang 14,influences of normal production and natural growth on the populations of Empoasca onukii(Matsuda)and Araneida in tea plantations were compared.Results showed that there was no significant difference in resistances of the three tea varieties to Empoasca onukii(Matsuda);the number of Araneida in Yungui is significantly smaller than in Yunkang 10 and Yunkang 14.Artificial tea picking,cultivation and biological pesticides can significantly control the number of Empoasca onukii(Matsuda),but have less influnce on Araneida.We should pay more attention to prevention of Empoasca onukii(Matsuda)in summer.
