Toxicity and Field Efficacy of Four Neonicotinoids on Harlequin Bug (Hemiptera: Pentatomidae)
2012
Harlequin bug, Murgantia histrionica (Hahn), is a pest of cole crops in the USA. Laboratory toxicity assays revealed that the neonicotinoid insecticides imidacloprid, thiamethoxam, dinotefuran, and clothianidin are toxic to harlequin bug nymphs; LC₅₀ = 0.57, 0.52, 0.39, and 0.39 ppm, respectively. Field experiments were conducted to evaluate the efficacy of these insecticides over time when applied as a one-time soil drench. Each of the 4 neonicotinoids provided significant control of harlequin bug for at least 14 d after application.
