不同茶树品种间小绿叶蝉类群数量动态与抗虫性比较

Comparison on the Population Dynamics and Leafhopper Resistance on Different Tea Cultivars

在不同无性系茶树品种中,小绿叶蝉类群数量的动态和抗虫性的强弱存在明显的差异。其中矮丰、云抗10号和云瑰具有较强的抗虫性,其次是长叶白毫、波上金台、云梅、雪芽100号和短节白毫,抗虫性弱的为景谷大白茶和云桃。两处茶地的比较表明,矮丰是抗虫性强的理想品种,景谷大白茶和云桃则是抗虫性差的茶树品种。这对无性系良种的筛选与推广,特别是对我国和云南省无性系良种茶园的建设与推广,提供了一定的科学依据。

The difference on the population dynamics of the leafhopper and resistance existed on different clonal tea plants. In our study the clonal EF showed the strongest resistance to leafhopper than other cultivars. The clonal JGDBC and YT showed the highest susceptibility. These represent the differences of insect resistance among tea cultivars cultivated in production.
