Overall, treatments were highly significant ( F = 12.53; df = 6; p < 0.0001), causing greater mortality of all D. suzukii life stages (larvae at 4 DAA, pupae and adults at 10 DAA) than the control, with excellent activity (above 90%) in 3.5 × 10 8 and 3.5 × 10 7 cells mL −1 treatments, while the others showed fairly good efficacy of more than 60%.
