Searching for a new alternative to A. diaperinus control, it was evaluated the action of spinosad in two concentrations (250ppm, 400ppm) and two doses (0.05 L/m2 and 0.1 L/m2), applied in poultry broiler facilities naturally infested by this coleoptera. Assessments of the infestation were held in weekly intervals, during 49 days after treatment, using traps following a modified model of Arend's. The percentage of effectiveness were calculated from the results of the number of adults and/or larval stages in control and treated groups. Spinosad at the concentration of 250ppm, applied at a dose of 0100L/m2, can be considered ineffective against these beetles. The application of 0050L/m2 of spinosad to 400ppm showed high efficacy, however, short residual period. The dose of 0100L/m2 (spinosad 400ppm) demonstrated, between treatments, greater persistence of effectiveness against Alphitobius diaperinus, reaching efficacy of 100% against larvae of A. diaperinus, observed after the 7 th day post-treatment.
