Ecologia de mosquitos (Diptera, Culicidae) em áreas do Parque Nacional do Iguaçu, Brasil: 1 Distribuição por hábitat

Abstract

A study of the mosquito fauna in the Iguaçu National Park focused on population behavior in four biotopes with different types of plant cover inside the Park. Systematic bimonthly diurnal and nocturnal human bait and Shannon trap captures were conducted in both forest and domiciliary environments over the course of 24 months. A total of 20,273 adult mosquito specimens belonging to 44 species were collected: Ochlerotatus serratus (10.3%), Haemagogus leucocelaenus (9.7%), Mansonia titillans (9.6%), and Chagasia fajardoi (8.8%) were the most frequently captured mosquitoes. Anopheles cruzii, Runchomyia theobaldi, Wyeomyia aporonoma, and Wy. confusa were captured almost exclusively in well-preserved areas with dense forest cover. Culex nigripalpus, Oc. pennai, Oc. serratus, Sabethes purpureus, and Sa. albiprivus were captured in three essentially sylvatic biotopes. Species captured in the forest areas around a dam were: An. albitarsis s.l., An. galvaoi, An. evansae, An. fluminensis, Coquillettidia venezuelensis, Cq. juxtamansonia, Wy. quasilongirostris, and Onirion personatum, Ch. fajardoi, Cq. fasciolata, Cq nitens, and Ma. titillans were the most frequently captured species in a residential area.

Spatial and temporal variation of the phytoplankton community in a section of the Iguaçu River, Paraná, Brazil

“…Temperature of the Foz do Iguaçu municipality varies from around 3 °C to 40 °C, with an average of approximately 26 °C. The climate in general is humid, mesothermal and subtropical, without defined dry seasons, having an average annual rainfall of around 1.600 mm (Salamuni et al, 2002;Guimarães et al, 2003).…”

Seasonal variation of the phytoplankton community structure in the São João River, Iguaçu National Park, Brazil

“…Iguaçu National Park (INP) encompasses approximately 180.000 ha and it has about a 400 km perimeter, part of which boarders the Iguaçu River directly (Guimarães et al, 2003). The INP covers the largest fragment of Brazilian protected area within the Atlantic Forest and is considered one of the last remnants of this kind of vegetation in the southern region of the country (Ibama, 2008 (Figure 1).…”

Mosquitoes (Diptera: Culicidae) near a reservoir in the Western part of the Brazilian State of Santa Catarina

“…(Forattini 2002, p. 362). More studies should be developed in reserve areas in the region, which might have these mosquitoes, as in the National Park of Iguaçu (Guimarães et al 2003).…”
