The present study evaluated the efficacy of a third-generation anthranilic diamide insecticide, tetraniliprole, against four pests of stored grains: Trogoderma granarium, Rhyzopertha dominica, Tribolium castaneum, and Sitophilus oryzae. Trials were conducted using wheat, rice, and maize treated with various doses (0.01–10 mg tetraniliprole/kg grain), to assess mortality, progeny suppression, and persistence. Surface treatments on steel, ceramic tile, cement, and plywood were also conducted. Results revealed that S. oryzae was the most susceptible species, suffering 97.27 % mortality on 10 ppm treated wheat, at 14 days of exposure, while the most tolerant was T. granarium. Among all tested insects, the highest mortality rates were noted on treated wheat, followed by rice and maize. The progeny proportion was significantly decreased on treated commodities, with complete suppression noted for S. oryzae on wheat and rice at 10 ppm. Persistence trials demonstrated that tetraniliprole retained efficacy over time, particularly against S. oryzae, though effectiveness diminished after 60 days of exposure. Surface treatments indicated higher mortalities on steel and cement compared to ceramic tile and plywood.
