Resumo
Nas cidades brasileiras, o processo de urbanização mal planejado, de forma geral, acarretou inúmeros problemas sob o ponto de vista de Saúde Pública. Atualmente, são muitos os exemplos de doenças que se tornaram endêmicas nos municípios. A degradação ambiental impulsionou um processo seletivo em que os atributos das espécies repercutiram em sucessos adaptativos para algumas delas. Dessa forma, tornaram-se bastante robustas as associações sinantrópicas, e mais difícil o controle de vetores. Possivelmente, esse sucesso adaptativo tenha sido potencializado por alguns fatores: o homem subestimou a capacidade dos animais de se adaptarem a ambientes urbanos ou simplesmente ignorou tal processo ecológico. O objetivo do presente trabalho foi realizar um levantamento através de visitas casa-a-casa, de larvas de Culicidae em diferentes tipos de criadouros, em área urbana do município de Santa Bárbara d´Oeste, SP. Pelo menos 10 espécies foram encontradas, sendo que algumas possuem elevada importância epidemiológica e estão envolvidas em diversos ciclos zoonóticos. As quatro espécies mais abundantes foram, pela ordem, Ae. aegypti, Ae. albopictus, Culex quinquefasciatus e Ae. fluviatilis. As espécies mais raras geralmente estiveram associadas a áreas com cobertura vegetal. Os criadouros que mais predominaram foram dos tipos 2 (prato e vaso de plantas), 3 (lata, pote, frasco) e 7 (outros removíveis). Foi possível identificar as áreas com maior probabilidade de encontro de cada uma das espécies de culicídeos, assim como os seus criadouros preferenciais. A confecção de mapas cartográficos auxiliou no processo de visualização das áreas do município e distribuição de espécies e criadouros. Quanto ao número de ocorrências, as espécies de culicídeos apresentaram preferência por alguns tipos de criadouros, e estes não foram independentes das Áreas do município...
On the whole, innumerable problems have been derived from the implementation of urbanisation processes that are misconceived. In the context of public health, there are several examples of diseases that are currently deemed to be endemic in the Brazilian municipalities. The degradation of the environment stimulated the development of selective processes in which the species attributes resulted in adaptive success regarding some of such species. Therefore, synanthropic associations became considerably robust, and the control of vectors became more difficult. This adaptive success may have been potentialised by some factors: humans underestimated the ability of animals to adapt to urban environments or they simply ignored such an ecological process. The current work is aimed at conducting a survey of Culicidae larvae present in different types of breeding sites (egg-laying containers or oviposition surfaces), on a home-by-home-visit basis. Santa Bárbara d’Oeste (state of São Paulo, Brazil) was the urbanised study area. At least ten species were found and some of them, which possess a high level of epidemiological importance, are entailed in several zoonotic cycles. The four more abundant species were, in decreasing order of occurrence, Ae. aegypti, Ae. albopictus, Culex quinquefasciatus, and Ae. fluviatilis. The rarer species were usually associated with vegetated areas, and the breeding sites “2”, “3”, and “7” predominated in this study. It was possible to identify the areas that presented the higher chances of encountering each of the culicid species and their respective preferential breeding sites. The cartographical mapping enabled the visualisation of the distribution of the species and breeding sites over the urban areas. Regarding the occurrences of the species, the culicids exhibited preference for specific breeding sites, and such sites were not independent... (Complete abstract click electronic access below)
