“…They are widely used in Aedes aegypti monitoring programs of Brazilian urban areas [ 16 ]. However, this trap also seems to work well for some groups of mosquitoes that occur in wild areas, especially those that use phytotelmata breeding sites, such as mosquitoes of the genera Aedes , Haemagogus , Limatus , and Toxorhynchites [ 17 , 18 ].…”

The present study aims to analyze the effectiveness of ovitraps in the capture of Hg leucocelaenus eggs and evaluate the influence of the dry and rainy seasons on their abundance and hatching rates. The eggs were collected in the Atlantic Forest of State of Rio de Janeiro, Brazil, an area in which the yellow fever virus is known to circulate. We distributed 15 ovitraps in three sampling points, with five ovitraps per point. We distributed 15 ovitraps in three sampling points on trees within a forested area, which were sequentially numbered, monitored, and replaced every two weeks from October 2016 to April 2018. There was a high dominance of Hg. leucocelaenus eggs (98.4%) and a variation in egg hatching rates between the wet and dry seasons. These rates were 1.5 times higher in the rainy season than in the dry season. The rainy season also showed a greater abundance of eggs and higher values of ovitrap positivity and egg density indexes in the installed ovitraps. The abundances of Hg. leucocelaenus eggs were positively correlated with mean monthly temperature and air humidity but not significantly correlated with accumulated precipitation. These results, as well as their implications for the possible use of ovitraps to monitor vector mosquitoes of yellow fever in the study region, are discussed.

Arboviral diseases such as dengue, Zika and chikungunya infect populations in countries with predominantly tropical and subtropical environments, where their vectors are adapted. This research aimed to identify potential favorable sites to Aedes aegypti reproduction at rural communities where dengue, Zika and chikungunya prevalence is high, geographically located in Goiás-Brazil, and to analyze the relationship between breeding sites quantity and these three arboviruses seroprevalence. In 137 families from 13 rural communities, information was obtained between October/2021 and November/2021. Data were analyzed quantitatively and qualitatively trough Pearson's correlation and Cluster analysis. 92.7% of the households, possessed, at least one potential mosquito breeding ground. Water containers, despite of being uncovered, retain water and create an ideal environment for mosquito's evolutionary cycle. Potential breeding grounds were observed related, mainly, to the lack or absence of precariousness of basic sanitation services. The community with the highest number of breeding grounds and suspected vectors of Aedes aegypti was also the one that resulted in the highest number of patients with dengue fever. The presence of places for Aedes aegypti development in the studied environment may be responsible for arboviruses spread, affecting a significant part of the population. Therefore, the present study might warn municipal health authorities for implementing public policies such universal sanitation, as a measure that indirectly provides vector control especially Aedes aegypti, when it also proliferates in rural areas, risking the population health.
