Temperature is one of the most important factors that affect insecticide toxicity and daily and seasonal fluctuation of insect occurrence in crop field. However, there is little information on the relationship between the temperature and insecticide toxicity of the small brown planthopper (SBPH). In this study, the influence of temperature on the toxicity of insecticide was examined. The toxicities of fipronil and three neonicotinoids, dinotefuran, imidacloprid, and thiamethoxam were found to be positive temperature coefficient and that of etofenprox was negative one. Carbamates (carbosulfan and fenobucarb) were showed no relations with temperature increase. As for the resistant SBPH strains, the toxicity ratio (RT) between 20 and 30℃ of imidacloprid-resistant strain exhibited much higher (204.4 - fold) than that (1.0 - fold) of etofenprox-resistant one. The mean mortality of after-overwintering populations showed also significantly higher than that of before-overwintering populations. This study provides a clue to the effect of temperature rise on insecticide efficacy and gives the theoretical basis for the effective use of chemical insecticides and resistance management to control SBPH suffering the overwintering.
