The Development,Reproduction and Spatial Distribution of Lesser Green Leafhopper (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 Poissons Distribution.The results of the different tea cultivars resistance to Camellia sinensiscan could be used in practice.
