Due to its prevalence and the severity of its manifestations Chagas disease is still today a major public health problem in affected countries. Knowing the importance of an active, participatory and permanent surveillance involving community participation for the success of prevention and harm reduction the present study aimed to evaluate the knowledge of the vector of Chagas disease living in rural communities with a history of triatomine capture the city of Natal, Rio Grande do Norte - Brazil, and to verify the presence and association of environmental indicators of risk for infestation of insects in these communities. For this, we used a semi-structured questionnaire administered to the resident responsible for the residence containing questions about their socioeconomic profile and also issues related to the vector of Chagas disease. For assessment of environmental risk indicators, we used a structured interview. It was observed lack of knowledge of the residents on issues related to the life cycle of the insects and on the time of day and the time of year when more appear and how are born. In addition, lack of guidance was detected in the population as to what action to take when a vector is found at his residence. It was an observed association between socioeconomic profile and knowledge of residents about the triatomine. In 10.75% of the homes visited were captured triatomine and association was observed between the catch and the presence of risk factors for the presence of these insects. Among the indicators are present the structure of households, peridomicile characteristics and the presence of wild animals (p<0.05). In this study, it is evident the need for greater disclosure of information related to the vector of the disease, in order to prevent its spread in the studied areas. The observed association between the capture of insects and the presence of environmental risk indicators in the communities emphasize the importance of early identification of these factors in order to improve prevention and control
