Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 4 - Survey of resting adults and synanthropic behaviour in South-Eastern, Brazil

Abstract

Resting adults Culicidae were collected from January 1992 through January 1993 in several habitats of the Ribeira Valley region. The diversity of species found among them suggested that the vegetation remaining within human settlements favored the survival and the population increase of some mosquitoes. Among there are: Ae. scapularis, Ae. serratus, Cx. (Culex), Cx. nigripalpus and Cx. (Melanoconion) such as Cx. ribeirensis. That preservation role may be attributed to the rearing of livestock and the consequent increase in the number of blood sources. These species may be classified as hemisynanthropes and Cx. oedipus apparently evolving to the eusynanthropic status. On the other hand, An. cruzii showed an asynanthropic behaviour, with a low degree of survival in the modified human environment. Epidemiological implications of the data are mentioned.

Ecology of mosquitoes (Diptera: Culicidae) in areas of Serra do Mar State Park, State of São Paulo, Brazil. II - Habitat distribution

“…quinquefasciatus is historically considered as a typical urban mosquito (Causey et al 1945, Deane 1951, Forattini et al 1978b, 1993c. In the present study, this was the only truly eusynanthropic species found (Fig.…”

“…nigripalpus has demonstrated in other studies a more varied behavior. Lourenço-de-Oliveira (1984) collected this Culicinae in a deeply altered area in the State of Rio de Janeiro and Forattini et al (1993c) reported its preference for anthropic modified environment. Forattini et al (1995b) remarked that the behavior of Cx.…”

Periodic dynamic systems for infected hosts and mosquitoes

“…The main motivation for the construction of the model here presented as well as the applications made was the recent studies by Forattini et al 4 on mosquitoes at an experimental rice irrigation system 5,6,7,8,9 .…”

Novos registros e potencial epidemiológico de algumas espécies de mosquitos (Diptera, Culicidae), no Estado do Rio Grande do Sul

“…As fêmeas são ecléticas, mas parecem preferir grandes mamíferos para o repasto sanguíneo 1,11 . São encontrados com certa abundância em ambientes silvestres primitivos e matas secundárias e apresentam pouca tendência à domiciliação 21,22 . 15,16 .…”
