Toxicity of Insecticides on Thrips palmi Karny and Thrips tabaci Lindeman (Thysanoptera: Thripidae) in Osaka Prefecture, Japan

Abstract

We determined the toxicity of insecticides by using the leaf-dipping method on two thrips species, Thrips palmi and Thrips tabaci. They were collected from 3 populations in Osaka Prefecture in 2017 and 2019, and the effects of 11 and 7 insecticides, respectively, for the two species were examined. The most effective insecticides against T. palmi were emamectin benzoate, fluxametamide, and flometoquin, whereas MEP and thiocyclam were effective against T. tabaci.
