Abstract:A preliminary investigation on the population dynamics of Empoasca vitis including adults and nymphs was conducted on conventional tea plantations of Wuhan from 2010 to 2011 and the control effects of 4 insecticides on the leafhopper (E. vitis) were evaluated. The results showed that the population dynamics of E. vitis were generally similar between 2010 and 2011 in Wuhan, and there were two peaks of abundance each year during which the first peak appeared from early June to middle July, and the second peak occurred from middle September to middle November. The first peak showed larger amount of E. vitis, while the second peak lasted longer. The occurred periods of adults and nymphs were different, nymphs arrived from middle April to late November, while the adults could be observed throughout the year. The control efficiencies of 15% indoxacarb EC, 24% chlorfenapyr SC and 20% Thiamethoxam and Lambda Cyhalothrin (9.4% lambda-cyhalothrin and 12.6% thiamethoxam ZC) on small green leafhopper were 61%88% at 1 day after administration, and above 90% at 3 days after administration, indicating these insecticides were effective.
