- Abstract
Empoasca vitis (Göthe) is a most serious pest in tea plantation. In this study, we sequenced 16S rRNA gene partial sequence for 101 individuals in 11 geographical populations of E. vitis. Based on them, we investigated genetic diversity, molecular variation and population genetic structure for the 11 populations. The 16S rRNA partial sequence is 493 bp long with a 77 % A + T-content. 11 variable sites and 13 haplotypes were obtained, and haplotype network showed that haplotypes in Sichuan province are far from original haplotype (H2). The haplotype diversity index was 0. 68812 of total population, ranging from 0 to 0. 80556 within each population. The Tajima’s D test for all populations or each single population did not reach significant level, it infered that the evolution and the abundance of E. vitis remained on quantitative level and fit well with the neutral model. AMOVA results demonstrated that genetic differentiation of E. vitis mainly occurred within population.
