Effects of insecticides on adult western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) collected from three eggplant greenhouses in Osaka Prefecture

Abstract

We determined the toxicity of 10 insecticides on adult western flower thrips, Frankliniella occidentalis (Pergande) using the leaf-dipping method. Two different populations of the thrips were collected from an eggplant greenhouse in Kaizuka City and one from Habikino City in Osaka Prefecture. Flometoquin achieved more than 90% mortality while acetamiprid, tolfenpyrad, and cyantraniliprole showed low corrected mortality in all populations.
