Abstract: The relative susceptible toxicity baseline of the tea green leafhopper, Empoasca vitis (GÖthe) to 8 insecticides were tested in this study. Also, the regional diversity of resisitance to 5 insecticides in Fujian Province was analyzed by the tea tip-dipping method. The results showed high toxicities to the tea green leafhopper of 8 insecticides, including Bifenthrin, Chlorfenapyr, Cyhalothrin, Imidacloprid, Beta-cypermethrin, Acetamiprid, Buprofezin and Cartap. Different resistance levels were found in the different sites. Higher resistance level was observed in Fuan population to Bifenthrin and Acetamiprid. The resistance indexes were 44.1 and 97.4 times, respectively. The resistance index to Imidacloprid was 11.8 times. The Beifeng population showed a middle-level resistance to Cartap and the resistance index was 16.4 times. The Wuyi mountain population showed a high-level resistance to Acetamiprid and the resistance index was 52.3 times. The tea green leafhopper collected from different sites displayed different sensitive to Chlorfenapyr.

Key words: Empoasca vitis (GÖthe);, insecticide susceptibility, regional diversity
