Effects of insecticides on adult loquat psyllids, Cacopsylla biwa

Abstract

We investigated the toxicity of 31 insecticides to adult loquat psyllids, Cacopsylla biwa, collected from loquat trees in Wakayama Prefecture. Alanycarb, chlorpyrifos, malathion, methidathion, phenthoate, ethiprole, silafluofen, and cartap were toxic, resulting in a corrected mortality of more than 90%.
