Objective To determine the killing effects of tetramethrin and dinotefuran mixtures on Blattella germanica, and to screen for the formula with a synergistic effect. Methods SPSS 22.0 software was applied to determine the regression equation of toxicity and median lethal concentration (LC50). The co-toxicity factor and co-toxicity coefficient were employed to evaluate the killing effects of tetramethrin and dinotefuran mixtures on B. germanica, and identify the optimal ratio of tetramethrin to dinotefuran. Results At 72 h after treatment, the LC50 values of tetramethrin and dinotefuran against the male adults of B. germanica were 1 376.86 mg/L and 3.97 mg/L, respectively. When the mass ratio of tetramethrin to dinotefuran was between 231:1 and 3 123:1, the mixture had a significant synergistic effect. The optimal mass ratio was 360:1, with a co-toxicity coefficient of 190.09 and an LC50 of 366.70 mg/L at 72 h after treatment. Conclusion The mixture of tetramethrin and dinotefuran shows a significant synergistic killing effect on B. germanica.
