management of fall armyworm (FAW), Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae), success of the measure could be compromised by the prevailing environmental temperature since it significantly affects toxicity of insecticides and thus their efficacy. To determine the temperature-toxicity relationship in FAW, the effect of post-bioassays temperature (range, 15-35 °C) on the toxicity of eight insecticides from different classes was evaluated using a feeding bioassay method. From 20–35 °C, the toxicities of emamectin benzoate, lufenuron, imidacloprid, chlorpyrifos, and chlorantraniliprole increased 1.24, 1.31, 2.25, 2.29, and 3.46-fold (i.e. positive temperature coefficient), respectively, whereas the toxicities of methomyl, spinosad, and cypermethrin decreased 2.24, 3.17, and 3.95-fold (i.e. negative temperature coefficient), respectively.
