Abstract

Since mosquito immatures had been previously reported found in bamboo internodes in the Brazilian state of Santa Catarina, a study was conducted from January to March 2011 to evaluate the mosquito fauna associated with artificially drilled bamboos in eight localities in the eastern region of this state. Ninety-one mosquitoes of the following species were recorded: Aedes albopictus (Skuse, 1894) (1.1%), Culex soperi Antunes & Lane, 1937 (11.0%), Onirium personatum (Lutz, 1904) (6.6%), Sabethes aurescens (Lutz, 1905) (38.5%), Sa. identicus Dyar & Knab, 1907 (16.5%), Sa. intermedius Lutz, 1904 (3.3%), Sa. purpureus (Theobald, 1907) (1.1%), Trichoprosopon pallidiventer Lutz, 1905 (6.6%), Trichoprosopon soaresi Lane & Cerqueira, 1942 (2.2%) and Wyeomyia limai Lane & Cerqueira, 1942 (24.2%). The finding of Ae. albopictus in perforated bamboos and the diversified mosquito fauna, whose biology is mostly poorly known, indicates the need of more detailed studies. Bamboo internodes constitute an important breeding place for mosquitoes of several species in the studied area. Sabethes intermedius and Culex soperi are reported for the first time in the state.

Highlights

The immature forms of several mosquito species develop in bamboos and have been studied in southern Brazil (LOZOVEI, 2001; MÜLLER et al, 2008), and those found in artiicially drilled bamboo internodes from the Atlantic Forest in Santa Catarina State have been reported (MÜLLER et al, 2008)
From January to March 2011, immature forms of mosquitoes were collected from bamboos in a secondary forest in Peri Lagoon Park, Pantanal (27°36’35.27”S and 48°28’56.3”W), two growths of bamboos in Conceição Lagoon Hill (CLH, 27°35’59.00”S and 48°28’54.34”W, 27o35’53.65”S and 48o28’47.11”W), Ratones (27°30’17.33”S and 48°27’57.15”W) and Environmental Conservation Unit Desterro (UCAD, 27°31’55.69”S and 48°30’43.08”W), all on Santa Catarina Island, Florianópolis Municipality, and in Spitzkopf Park (SKP, 26°59’42.22”S and 49°6’25.72”W, Blumenau Municipality), Itapema (27°5’20.87”S and 48°38’19.52”W) and Santo Amaro da Imperatriz (SAI, 27°43’57.33”S and 48°48’31.38”W), in the eastern mainland part of that state
Immature forms were reared in small vials in the laboratory, utilizing distilled water mixed with water from internodes, at 25±1oC, until obtaining adults, which were identiied, preserving exuviae in 80% ethanol

Summary

Introduction

The immature forms of several mosquito species develop in bamboos and have been studied in southern Brazil (LOZOVEI, 2001; MÜLLER et al, 2008), and those found in artiicially drilled bamboo internodes from the Atlantic Forest in Santa Catarina State have been reported (MÜLLER et al, 2008). From January to March 2011, immature forms of mosquitoes were collected from bamboos in a secondary forest in Peri Lagoon Park (abbreviated PLP, 27°43’59.30”S and 48°30’54.41”W), Pantanal (27°36’35.27”S and 48°28’56.3”W), two growths of bamboos in Conceição Lagoon Hill (CLH, 27°35’59.00”S and 48°28’54.34”W, 27o35’53.65”S and 48o28’47.11”W), Ratones (27°30’17.33”S and 48°27’57.15”W) and Environmental Conservation Unit Desterro (UCAD, 27°31’55.69”S and 48°30’43.08”W), all on Santa Catarina Island, Florianópolis Municipality, and in Spitzkopf Park (SKP, 26°59’42.22”S and 49°6’25.72”W, Blumenau Municipality), Itapema (27°5’20.87”S and 48°38’19.52”W) and Santo Amaro da Imperatriz (SAI, 27°43’57.33”S and 48°48’31.38”W), in the eastern mainland part of that state.
