Sampling comments: "we assessed the presence of A. azarae in six crop field borders (located at distances ranging between 200 and 500 m from each other) by placing 15 trapping stations spaced at 10-m intervals in each border. There were two Sherman traps at each trapping station, which were baited with a peanut butter, bovine fat and oat mixture. Traps were checked every morning for three consecutive days"
