Abstract

Abstract

Resistance of tea leafhoppers to bifenthrin was monitored consecutively from 2013 to 2015.Variations on the resistances of the insects to bifenthrin and acetamiprid at 4different sites in Fujian were determined using a tea tip-dipping method in 2014.The results indicated that the population at the tea gardens in Huanxi was 2.7times higher in its resistance to bifenthrin in 2014 and 8.6times higher in 2015 than in 2013.The resistance of leafhoppers to bifenthrin and acetamiprid differed significantly at different sites.The Huanxi population showed a low-resistance to bifenthrin and acetamiprid with a resistance index of 8.2times;at Jingu,a mid-resistance to bibenthrin and a low-resistance to acetamiprid were observed;at Huotong,a high-resistance to bifenthrin and a lowresistance to acetamiprid were found;and,at Dongfeng,high-resistances to both bifenthrin and acetamiprid with resistance indices of 75.7and 102.4times,respectively,were evident.Hence,continual application of bifenthrin and acetamipridin with large doses would further increase the leafhopper's resistance to the insecticides.It was,therefore,recommended alternating the use of different pesticides to curtail rapid development of insecticideresistance of the insects.
