Effect of insecticides on the larvae of loquat psyllid, Cacopsylla biwa Inoue

Abstract

The toxicities of various insecticides were determined using a bait twig method on larvae of the loquat psyllid, Cacopsylla biwa, collected from loquat trees in Wakayama Prefecture. Chlorpyrifos, malathion, methidathion, phenthoate, ethiprole, fenpropathrin, tralomethrin, acetamiprid, clothianidin, imidacloprid, and cartap were toxic and resulting in a corrected mortality rate >90%.
