Abstract

Abstract

This study aimed to evaluate the effect of several pesticides used at tea gardens for controlling the tea green leafhoppers(TGLs)on mymarids,a TGL-egg-parasitoid.Sweeping nets and microscopic examination were used to determine the count and parasitism of mymarid population at the sites.It was found that 15% tolfenpyrad EC,15% indoxacarb EC and 2.5% bifenthrin EC significantly reduced the mymarid count as compared to CK(spread with water)after a 3-daypesticide treatments.The parasitism rates of mymarid on the 14 thand the 21 st day after treatments with the pesticides were also significantly lower than CK.The pesticides,15%tolfenpyrad EC and15%indoxacarbEC,were effective and fast in controlling TGLs.All 3 pesticides showed a greater effect on mymarids than the biopesticide,veratridine.It appeared that application of these pesticides negatively affected the population as well as the parasitism rate of mymarid.
