Ecological aspects of South American Trypanosomiasis: XI - domiciliation of Panstrongylus megistus and its enzootic potential

, 1977
Foram observadas algumas características de populações locais de Panstrongylus megistus e de mamíferos domiciliados e silvestres. Confirmou-se o papel das matas residuais na permanência local da população triatomínica, bem como o caráter agrupado da dispersão do inseto com nítida preferência pelos anexos domiciliares.

Ecological aspects of South American Trypanosomiasis: VIII - Local domiciled and wild pattern of Panstrongylus megistus

, 1977
Local pattern of domiciled and wild distribution of Panstrongylus megistus was observed through artificial and natural ecotopes investigation. The bug was found inhabiting periodomestic dwellings and hollow trees in the sylvatic environment serving as shelters for wild animals. This was mainly represented by spots of remaining forests.

Ecological aspects of South American Trypanosomiasis: XII - Regional variation of the Panstrongylus megistus domiciliary tred

, 1978
The development of spontaneous colonies of Panstrongylus megistus in experimental fowlhouses showed regional variation with positive results in regions with an annual dry season, and negative ones in regions without this well-marked period. Beside this, the influence of the forest cover was suggested.

Rationalizing Historical Successes of Malaria Control in Africa in Terms of Mosquito Resource Availability Management. [PDF]

, 2004
Environmental management of mosquito resources is a promising approach with which to control malaria, but it has seen little application in Africa for more than half a century. Here we present a kinetic model of mosquito foraging for aquatic habitats and

Global Climate Change and the Resurgence of Tropical Disease: An Economic Approach [PDF]

We study the impact of global climate change on the prevalence of tropical diseases using a heterogeous agent dynamic general equilibrium model. In our framework, households can take actions (e.g., purchasing bednets or other goods) that provide partial ...

[Ecological aspects of South American trypanosomiasis. XV. Development, variation and permanence of Triatoma sordida, Panstrongylus megistus and Rhodnius neglectus in artificial ecotopes].

Revista de saude publica, 1979
Spontaneous colonies of Triatoma sordida, Panstrongylus megistus, and Rhodnius neglectus developed in experimental fowlhouses were observed for the conditions for their development and the variation and permanence of their components. T. sordida colonization and dispersal is favored by open areas, mainly pasture lands where many dry trees remain as the

Ecological aspects of South American trypanosomiasis: XXI - Sylvatic triatominae behaviour related to the domiciliary and peridomiciliary environments

, 1984
Apresentam-se os resultados obtidos com a observação da presença triatomínea em três localidades, uma delas caracterizada por estar submetida a vigilância anual ininterrupta, e duas por terem sido expurgadas respectivamente seis e um ano e meio antes. As duas primeiras situam-se em áreas de endemicidade de Panstrongylus megistus e a terceira em região ...

[Ecological aspects of South American trypanosomiasis. XX-- Development and annual cycles of Panstrongylus megistus colonies in artificial ecotopes, in peri- and extradomiciliary environments].

Revista de saude publica, 1984
Spontaneous colonies of Panstrongylus megistus developed in experimental fowlhouses were observed for the conditions of their development, variation and permanence of their components. Data were also obtained on their annual cycles and survival. The annual cyclical rhythm showed an increase of adult production in the last quarter of the year, with a ...

Ecological aspects of South American Trypanosomiasis: XIII - Domestic enzootic potencial in Panstrongylus megistus area submitted to epidemiological surveillance

, 1978
In certain areas of the State of São Paulo, Brazil, where transmission of tripanosomiasis by Triatoma infestans has been interrupted for at least six years, ah investigation of domestic enzootic situations has been carried out. A low incidence (0.3%) of infected dogs was found and their infection associated to the existence of Panstrongylus megistus ...
