The tested insecticides were diazinon (EC 60%), cypermethrin (EC 40%), fipronil (EC 2.5%), imidacloprid (SC 35%) and a botanical insecticide oxymatrine (Kingbo, AS 0.6%). Fipronil had the highest efficacy among all tested insecticides (LC50 = 17.97 ppm). However, imidacloprid had the lowest efficacy (LC50 = 2303 ppm). The oxymatrine was effective (LC50 = 69.94 ppm) after fipronil. M3 ER -
