Eficiência de alfacipermetrina e cipermetrina no controle de triatomíneos em Camalaú, no sul da Paraíba (Hemiptera: Reduviidae)

We sprayed, in three groups of Domiciliary Units, 10 and 15 g of alphacypermethrin and 31.3 g of cypermethrin per pump of 10 liters, equivaling, if applied on 250 [squared meters), respectiveliy, to 60 and 40 mg of a alphacypermethrin [per squared meter] and 125,2 mg of cypermethrin [per squared meter]. The invasion, colonization and cumulative indices in the houses and the positivity index in shelters near houses were very low and similar in the three groups, in the 15 months of evaluation, indicating that alphacypermethrin can replace cypermethrin. Triatoma infestans predominated in the Domiciliary Units before treatment and T. brasiliensis and T. pseudomaculata predominated after it.
