Insecticide toxicity on melon thrips, Thrips palmi Karny (Thysanoptera: Thripidae), collected from cucumber greenhouses in Osaka Prefecture

Abstract

The toxicity of five insecticides on adult melon thrips, Thrips palmi Karny, was compared among three populations collected from cucumber greenhouses in Osaka Prefecture by using the common bean leaf dipping method. The corrected mortality rates associated with avamectin, spinosad, and spinetoram were low in a population sampled in Kanan Town in 2014.
