Evaluation of a low-cost trap on capture and possible control of the Aedes aegypti mosquito population

Abstract

The Aedes aegypti mosquito is the primary vector of Zika, Chikungunya and Dengue in Brazil and other parts of the world. Thus, its control is essential, but also a challenge for public health. This study aims to evaluate the performance of a low-cost trap in capturing eggs and its possible impact on reducing the infestation of Aedes aegypti. The interventional study was carried out in neighborhoods of Salvador, state of Bahia, Brazil, where mosquito capture was evaluated before and after the intervention using the low-cost trap. The study was performed comparing the results of the years 2019 and 2020. In the months before and after the intervention, a control trap, of proven efficiency, was used to determine mosquito infestations in the two districts. The analysis also took into account the rainfall in the periods of weeks prior to data collection. The influence of the low cost trap on the reduction of Aedes aegypti infestation was statistically observed.
