Description
Summary:Early detection of residual populations of domestic triatomine bugs that survive insecticide treatment is a key component of successful evaluation and vigilance for Chagas disease control. We have recently demonstrated that sheets of paper, tacked on to the walls of infested houses, can become streaked with the faeces of triatomine bugs and thus reveal thepresence of an infestation. In thispaper, wepresent a simple key to differentiate the faecal streaks of triatomine bugs from those of other domestic arthropods such as cockroaches, ticks and cimicid bedbugs. Determinar as populações de barbeiros residuais nas casas depois de borrifação com inseticidas é um componente importante na vigilância e evolução do controle dos vetores da doença de Chagas. Recentemente, mostramos que folhas de papel, afixadas na parede das casas infestadas, podem ser manchadas com fezes dos triatomineos, assim revelando a infestação. Neste trabalho, apresentamos uma chave simples para diferenciar as fezes dos triatomineos de outros artropodos, como baratas, carrapatos e percevejos de cama.
