In recent decades, the epidemiological situation of vector-borne diseases has become progressively worse, as well as the introduction of new diseases, as a consequence of the alteration of the environment due to anthropogenic activities, which led to the adaptation and dispersion of originally wild urban areas. Thus, entomological surveillance methods should incorporate new surveillance technologies to allow for the attainment of risk indicators and better control of vector species in a timely manner. The use of chemical attractants is one of the prerequisites for improving insect traps, seeking to increase the sensitivity of these equipment. In order to do so, the target species will be created in the laboratory and tested for various chemical attractions in the market, as well as their association, such as carbon dioxide (CO2), 1-octen-3-ol (octenol), lactic acid (Lurex®), phenols and butanone, acetic acid among others. The tests will be performed in a controlled situation using olfactometers and later coupled in electric traps exposed in loosening rooms. The analysis of the results will be given by comparing the frequency of specimens attracted due to the exposure of certain attractiveness or associations between them and also by the optimum trap density with the addition of the selected attractive in a controlled situation.
