Immediate and Delayed Mortality of Tribolium confusum Adults and Larvae on Concrete Surfaces Treated with Chlorantraniliprole

Adults and larvae of Tribolium confusum were exposed for 1, 2, 3, 4 and 5d on concrete treated with chlorantraniliprole SC at four doses (0.01, 0.05, 0.1 and 0.5 mg active ingredient/cm²). Then, the adults and larvae alive were transferred on untreated concrete and delayed mortality was evaluated after 7d. Larval mortality ranged from 61.1 to 78.9% while adult mortality ranged between 40.0 and 70.0%, after 5d. Delayed mortality was high for both life stages, reaching 97.2 and 100.0% for adults and larvae, respectively. To conclude with, chlorantraniliprole is an effective management tool against T. confusum on concrete surfaces.
