Monitoramento dos mosquitos Aedes aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae) na Universidade Federal de Mato Grosso, campus Cuiabá

Abstract

This study aimed to verify the infestation levels of Aedes aegypti in the Federal University of Mato Grosso, Cuiabá Campus. Ovitraps were installed, monthly, in 10 different locations, where there was a great influx of people, throughout the Campus, from January to June 2015. The traps remained installed for 5 days and then collected and sent to the UFMT’s Medical Entomology Laboratory. Each ovitrap consisted of a black plastic container and an Eucatex ovipaddle, and a solution containing 270 ml of water and 30 ml of hay infusion, prepared in the proportion 20.8 g of hay to 2.5 L of water and left in a gallon closed by a week for decomposition of the vegetable matter. Ovitrap Positivity Index (OPI) and Egg Density Index (EDI) were used to calculate the infestation site and the females’ most and least reproductive seasons, respectively. The Sanitary Engineering was the place that had the highest number of mosquito eggs, and April the period with the greatest female reproduction of the Aedes aegypti. It was concluded that, with the constant presence and homogeneous distribution of Aedes aegypti in the Campus, it is necessary a more rigorous monitoring, with more efficient strategies and practices to combat the mosquitoes, and continuing health education, so that local people acquire habits that promote health and prevent the diseases.
