茶小绿叶蝉在不同茶树品种上的生长发育,生殖及空间分布

研究表明茶小绿叶蝉(Empoasca flavescens Fabricius)在云南大叶茶无性系良种云抗十号、云抗十四号、长叶白毫、矮丰上的生长发育历期、成活率、田间自然种群虫口数量、卵数量、卵分布等方面,皆有明显差异;说明这些品种对茶小绿叶蝉的抗性有差异,上述品种中矮丰对茶小绿叶蝉的抗性最强,云抗十号的抗性较差。在生产实践中对不同品种间存在的抗性差异应加以充分合理的利用。茶小绿叶蝉的空间分布型为随机分布型;在空间分布型方面,各品种间无明显差异。

THE DEVELOPMENT, REPRODUCTION AND SPATIAL DISTRIBUTION OF LESSER GREEN LEAF-HOPPER (Empoasca flavescens ) ON DIFFERENT TEA CULTIVARS

Studies showed great differences in development, survival rate, natural population level, natural egg density of the lesser green leafhopper (Empoasca flavescens Fabricius.) reared on different tea (Camellia sinensis) cultivars (YK10, YK14, CYBH, RF) . These results revealed that there were differences of resistance to the lesser green leafhopper among the four cultivars . In our study the tea cultivar EF has the strongest resistance to lesser green leafhopper, the YK10 has the lowest resistance. All the spatial distributions of the Empoasca flavescens over the four different tea cultivars belongs to Poisson's Distribution. The results of the different tea cultivars resistance to Camellia sinensiscan could be used in practice.
