Resumo
Uma das principais estratégias de prevenção para as arboviroses é o controle vetorial. Nos últimos
anos, com o contínuo aumento no número de casos de dengue, a oferta de armadilhas direcionadas
ao controle da população desses mosquitos tem sido relevante, tanto em nível individual, para o
controle intradomiciliar, como no nível populacional, para a vigilância epidemiológica. Nesse contexto,
o presente trabalho se propõe a avaliar a eficácia da BioaedesTrap, desenvolvida para capturar
fêmeas fecundadas de mosquitos dos gêneros Aedes e Culex, por meio de três principais atrativos:
liberação de vapor d'água, ambiente escuro, atrativo bioquímico, além presença de um cartão adesivo
que reduz a possibilidade de escapes. Para tanto, foram instaladas 14 armadilhas em espaços
urbanos com diferentes finalidades e fluxo de pessoas, tais como clube esportivo, universidade, prédio
residencial, escritório comercial e complexos de quadras de areia, localizados nos municípios de São
Paulo-SP e Barueri-SP. As armadilhas ficaram expostas por um período aproximado de 50 dias, entre
as semanas epidemiológicas 13 a 21 de 2024, instaladas em áreas cobertas e descobertas. Nesse
período, foram capturados 840 espécimes, sendo 652 fêmeas de Aedes aegypti, 23 fêmeas de Aedes
albopictus e 15 fêmeas de Culex sp, resultando em uma eficácia de 77,4% para fêmeas de A. aegypti.
A influência dos determinantes ambientais como temperatura, umidade relativa e pluviosidade
também foi avaliada, confirmando boa funcionalidade da armadilha em temperaturas entre 16,6 -
32,8ºC, umidade entre 67-83% e pluviosidade entre 0 – 20,3 mm. Tais resultados nos permitem
afirmar que a BioaedesTrap tem bom desempenho em áreas urbanas, de alto e baixo fluxo
populacional, em áreas internas e externas, capturando predominantemente fêmeas de Aedes
aegypti, vetor de dengue, zika e chikungunya.
One of the main strategies for preventing arboviral diseases is vector control. In recent years, with the continuous increase in the number of dengue cases, the use of traps aimed at controlling the population and reproduction of these mosquitoes has become relevant, both at the individual level for household control and at the population level for epidemiological surveillance. In this context, the present study aims to evaluate the effectiveness of the BioaedesTrap, developed to capture fertilized female mosquitoes of the Aedes and Culex genera, through four main attractants: release of water vapor, dark environment, biochemical attractant, and the presence of an adhesive card that reduces the possibility of escape. For this reason, 14 traps were installed in urban spaces with different purposes and people flow, such as sports clubs, universities, residential buildings, commercial offices, and sand court complexes, located in the municipalities of São Paulo-SP and Barueri-SP. The traps were exposed for an approximate period of 50 days, from epidemiological weeks 13 to 21 of 2024, installed in both covered and uncovered areas. During this period, 840 specimens were captured, including 652 females of Aedes aegypti, 23 females of Aedes albopictus, and 15 females of Culex sp., resulting in an effectiveness of 77.4% for Ae. aegypti females. The influence of environmental determinants such as temperature, relative humidity, and rainfall was also evaluated, confirming good functionality of the trap at temperatures between 16.6 - 32.8°C, humidity between 67-83%, and rainfall between 0 – 20.3mm. These results allow us to conclude that the BioaedesTrap performs well in urban areas, with both high and low population flow, in both indoor and outdoor areas, predominantly capturing Aedes aegypti females, the vector of dengue, zika, and chikungunya.
