Ecologia de mosquitos (Diptera: Culicidae) em áreas do Parque Nacional da Serra da Bocaina, Brasil.I - Distribuição por habitat

OBJETIVO: Estabelecer a influência exercida por três diferentes biótopos em áreas do Parque Nacional da Serra da Bocaina (PNSB) sobre a fauna local de mosquitos. MÉTODOS: Foram realizadas capturas mensais em ambiente silvestre e domiciliar, em isca humana, durante três diferentes períodos do dia, pelo período de 24 meses consecutivos, de janeiro de 1991 a dezembro de 1992. RESULTADOS: Foram capturados 11.808 espécimes adultos, pertencentes a 28 espécies. Ru. reversa e An. cruzii foram predominantes, respectivamente 52,5% e 17,9% do total de mosquitos. Ru. reversa representou 59,4% do total de espécimes no ambiente de mata fechada, seguida por Ru. frontosa com 10,5% e An. cruzii com 9,9%. No ambiente formado por campos de altitude e matas de galeria, o An. cruzii predominou com 48,1%, seguido por Ru. reversa com 28,1%. No ambiente modificado pelo homem, o An. cruzii predominou com 73,7% dos espécimes. Coquillettidia chrysonotum foi a única que se apresentou preferencialmente nesse biótopo: 14,9% no intra, 19,4% no peri e 65,7% no extradomicílio. An. cruzii e Ru. reversa foram constantes em todos os ambientes ao longo do ano. CONCLUSÕES: Com exceção de Cq. chrysonotum, com preferência pelo ambiente modificado pelo homem, os mosquitos apresentam hábitos assinantrópicos no PNSB. An. cruzii, embora assinantrópico, se aproxima e adentra o domicílio para realizar a hematofagia. A presença do Ae. serratus no extra e peridomicílio reforça a importância epidemiológica como vetora potencial de arboviroses. Os Sabethini apresentaram-se exclusivamente silvestres.

Entomological aspects of Chagas' disease transmission in the domestic habitat, Argentina

OBJECTIVE: To study the risk of Trypanosoma cruzi domestic transmission using an entomological index and to explore its relationship with household's characteristics and cultural aspects. METHODS: There were studied 158 households in an endemic area in Argentina. Each household was classified according to an entomological risk indicator (number of risky bites/human). A questionnaire was administered to evaluate risk factors among householders. RESULTS: Infested households showed a wide range of risk values (0 to 5 risky bites/human) with skewed distribution, a high frequency of lower values and few very high risk households. Of all collected Triatoma infestans, 44% had had human blood meals whereas 27% had had dogs or chickens blood meals. Having dogs and birds sharing room with humans increased the risk values. Tidy clean households had contributed significantly to lower risk values as a result of low vector density. The infested households showed a 24.3% correlation between time after insecticide application and the number of vectors. But there was no correlation between the time after insecticide application and T. infestans' infectivity. The statistical analysis showed a high correlation between current values of the entomological risk indicator and Trypanosoma cruzi seroprevalence in children. CONCLUSIONS: The risk of T. cruzi domestic transmission assessed using an entomological index show a correlation with children seroprevalence for Chagas' disease and householders' habits.

A comparison of bryophyte diversity in the Macaronesian Islands: island versus habitat approach

In this paper, we present a comparison of richness patterns and floristic similarity for bryophytes in the five most important altitudinal habitat types in the Macaronesian islands. We evaluate the importance of different factors discussed in the literature in predicting species diversity applying the traditional island approach and within the framework of the new habitat approach, including area, isolation, climatic factors, geological age and human influence. From the analysis of patterns of bryophyte species distribution for selected habitats across islands and archipelagos, we specifically test the hypothesis that (i) floristic similarity is primarily determined by climatic factors, but not by geographical distance due to high dispersal ability in this species group and (ii) bryophyte richness is best predicted by area, but not by geological age of the habitat due to very low endemicity or speciation rate and high colonization rate.

Synopsis of global scenario and forecasting surveys scenarios in risk habitat megacity (RHM)

The main objective of the paper is to provide a synopsis of global scenario and forecasting surveys. First, the paper will give an overview on existing global scenario and forecasting surveys and their specific scenario philosophies and storylines. Second, the major driving forces that shape and characterise the different scenarios will be identified. The scenario analysis has been provided for the research project Risk Habitat Megacity (HRM) that aims at developing strategies for sustainable development in megacities and urban agglomerations. The analysis of international scenario surveys is an essential component within RHM. The scenario analysis will be the basis and source for the development of own RHM-framework scenarios and for defining specific driving forces of change.

An unusual ground larval habitat of Aedes albopictus

Relata-se o encontro de criadouro de Aedes albopictus no solo. Tratou-se de buraco resultante da queda de árvore Piptadenia ("angico branco") onde foram coletadas larvas daquele mosquito, juntamente com representantes de Culex declarator, Cx. quinquefasciatus e Culex (Cux.) sp. do Grupo Coronator. O criadouro comportou cerca de 17 litros de água proveniente de chuvas locais. O achado deu-se em mata residual dentro de perímetro urbano da cidade de Pindamo-nhangaba no Vale do Paraíba, Estado de São Paulo, Brasil. Discute-se o significado do encontro como provável indicador de ecletismo comportamental e de adaptação do culicídeo ao ambiente antrópico.
