“…All vector species found in this study were collected in plastic containers and tire larvitraps, with a greater abundance in the forest edge and peridomicile environments. These observations suggest that such artificial breeding sites may be risk factors for infection with typical wild arboviruses [58,75].…”

Anthropogenic environments provide favorable conditions for some species, which is especially true of mosquitoes that present eclecticism at the moment of choice for the site of oviposition. In the present study, the diversity of mosquitoes was assessed by providing plastic containers, bamboo internodes, and tires in a forest, the forest edge, and peridomicile environments in a rural settlement area. Eighteen sampling points were chosen, delimited by a buffer of 200 m, placed in three environments: forest, forest edge, and peridomicile. In each environment, larvitraps were installed, separated by a minimum distance of 7 m and 1 m from the ground. A total of 10,131 immature mosquitoes of 20 species were collected. The most abundant species was Culex urichii (29.5%), followed by Trichoprosopon digitatum (27.1%), and Cx. (Melanoconion) spp. (10.4%). There was a difference in the composition of immature mosquito populations between larvitraps (p < 0.0005), and the plastic container hosted a greater diversity of species, whereas tires presented a greater abundance of individuals. The forest, forest edge, and peridomicile environments were also different with regard to diversity of immature mosquito populations (p < 0.0010). The forest edge was the environment with the greatest diversity of species, followed by the peridomicile and forest environments. In the forest and peridomicile, plastic container larvitraps had the greatest diversity, whereas the forest edge tire presented the largest number of individuals. Further, tire larvitraps collected the largest number of individuals in all environments. Ten species associated with the bamboo internode and tire were identified. The preference of species for artificial larvitraps, such as the plastic container and tire, even in wild environments was noted. These artificial objects may represent a risk factor for the population living in this region, as all vector species found in the study were present in plastic containers and tires.

Anthropogenic environments provide favorable conditions for some species, which are especially suitable for mosquitoes that present eclecticism at the moment of choice for the site of oviposition. The present study, the diversity of mosquitoes in plastic container, bamboo internode, and tire placed in forest, the forest edge, and peridomicile environments in a rural settlement area was assessed. Eighteen sampling points were chosen, delimited by a buffer 200 m, placed in environments: forest, forest edge, and peridomicile.

There was a difference in the composition of immature mosquito populations between larvitraps (p<0.0005), and the plastic container hosted a greater diversity of species, whereas tires presented a greater abundance of individuals. The forest, forest edge, and peridomicile environments were also significantly different with regard to diversity of immature mosquito populations (p<0.0010). The forest edge was the environment with the greatest diversity of species, followed by the peridomicile and forest environments. In the forest and peridomicile, plastic container larvitraps had the greatest diversity, whereas the forest edge tire presented the largest number of individuals. Further, tire larvitraps collected the largest number of individuals in all environments. We identified 10 species associated with the bamboo internode and tire. We also observed the preference of species for artificial larvitraps, such as the plastic container and tire, even in wild environments. These artificial objects may represent a risk factor for the population living in this region, as all vector species found in the study were present in plastic containers and tires.

“…Ressalta-se que os pontos com maiores densidades de ovos foram os com maior trânsito de pessoas, os pontos 1 e 2 são mais isolados. Neste caso, pode-se levantar a hipótese que a presença de pessoas está relacionada à presença do vetor por constituírem fonte de alimentação por serem estes insetos altamente sinantrópico e antropofílico (GOMES et al, 2005;SANTOS et al 2014).…”

Introdução: O Aedes aegypti é o principal vetor transmissor do vírus causador da dengue, Chikungunya, Zika Vírus e vírus da Febre Amarela urbana no Brasil, tendo uma ampla distribuição em países de clima quente e úmido. Atualmente, novas metodologias são necessárias para o controle do Aedes aegypti (Diptera Culicidae) diante de recentes surtos e reemergência destes vetores. Entre os métodos de controle dos culicídeos as armadilhas de oviposição vem sendo testadas e avaliadas em vários países, principalmente no Brasil.Objetivo: Testar a eficácia de um novo recipiente proposto como armadilha de oviposição de fêmeas do mosquito Aedes aegypti, comparando-o com a tradicional armadilha ovitrampa na Unidade Faculdade de Saúde Pública, Campus Quadrilátero da Sáude e Direito/USP. Métodos:Foram selecionadas quatro áreas no campus da Faculdade de Saúde Pública para instalação mensal de quatro armadilhas ovitrampa e quatro recipientes novos, a 1,00 metro do solo, totalizando oito armadilhas, com a finalidade de testar a eficiência na postura de ovos por fêmea do Aedes aegypti. O estudo ocorreu ao longo do ano 2019, entre os meses de fevereiro e setembro, compreendendo os períodos sazonais Primavera-Verão, Outono-Inverno de 2019.
