Four experiments were carried out to evaluate the efficiency of some powdered formicides on the control of the black leaf cutting ant, Acromyrmex crassispinus (Forel, 1909) (Hymenoptera: Formicidae), in Santa Maria county, from 1996 until 1998. Powdered formicides containing Fenthion at 50g a. i./kg, Imidacloprid at 4g a. i./kg, Betacyfluthrin at 2g a. i./kg, Chlorpyrifos at 20g a. i./kg and at 50g a. i./kg, Deltamethrin at 2g a. i./kg, Acephate at 750g a. i./kg and Diazinon at 10g a. i./kg were evaluated on big nests (>80cm of diameter). The big nests of this ant were efficiently controlled with 30g/nest of the commercial formulations of Fenthion, Diazinon and Chlorpyrifos (20g a. i./kg and 50g a. i./kg); with 3g/nest of the formulation of Acephate; with 5g/nest in dry season and 30g/nest in wet season of the powdered formulation of Deltamethrin.
