Ovitrap to monitor the incidence of Aedes aegypti

摘要

Dengue is considered an important arbovirus transmitted by female mosquito Aedes aegypti that affects humans, and is therefore a public health problem. Aim to monitor the incidence of A. aegypti through ovitraps in Ituiutaba municipality, MG and verify the influence of abiotic factors on the oviposition of the vector female. Were used 120 ovitraps in 29 neighborhoods the municipality to monitor the incidence of A. aegypti. The ovitraps were collected after 7 days, when egg counting was carried out and the association was made between abiotic factors. 70,821 vector eggs were collected, 22.8% during the month of October. The highest Ovitrap Positivity Index (69.47%) and Egg Density Index (106.17) occurred in October. It is noteworthy that in this period, the highest rainfall recorded in the year (317 mm) was verified. Our data show that ovitraps with beer yeast solution proved to be proved to be effective in monitoring A. aegypti and Culex incidence.
