Nova técnica para o estudo da fauna de mosquitos (Diptera: Culicidae) em internódios de bambus, com resultados preliminares

Developmental time of immature forms of Sabethes aurescens Lutz (Diptera, Culicidae) from artificially perforated bamboo in the rain forest of southern Brazil

“…The developmental periods of immature mosquitoes are usually 8-10 days, but those species in small, stable breeding places, such as bamboo internodes, spend more time to complete (Forattini 2002). However, the slower development may increase the risk of predation by Toxorhynchites (Lopes 1997), very frequent in our studies (Marcondes & Mafra 2003).…”

“…Holes, five-millimetres wide, were produced by an electric driller, in eight internodes of each of eight bamboo plants (Marcondes & Mafra 2003) University of Santa Catarina). The water sampled was discarded after one month of observation.…”

“…The present study intends to examine the period for development of larvae and pupae of Sa. aurescens, which are common in perforated bamboo internodes at Atlantic forest of southern Brazil (Marcondes & Mafra 2003).…”

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

“…aurescens and Wy. limai, collected in bamboo near the river Chapecó, are the predominant mosquitoes in artificially drilled bamboo at Santa Catarina Island (Marcondes & Mafra 2003). Both species occurred also in bamboo with natural holes near Curitiba, State of Paraná, among 17 species of mosquitoes (Lozovei 1998).…”

“…Immature forms were obtained from holes in stones, cut bamboo or bamboo with natural or artificial holes (Marcondes & Mafra 2003), and bromeliads. Immature forms were transported to the laboratory in Florianópolis in insulated packaging, which maintained the temperature between 15 and 20 o C. In the laboratory, the immature forms were separately reared in plastic vials, in 500 ml cups, covered with netting.…”
