A comunidade de abelhas (Hymenoptera, Apidae s. l.) em uma área restrita de campo natural no Parque Estadual de Vila Velha, Paraná: diversidade, fenologia e fontes florais de alimento

Abstract

ABSTRACT. The bee community (Hymenoptera, Apidae s. l.) in a restricted area of native grassland in the Vila Velha State Park, Paraná: diversity, phenology and food plants. A standardized survey of bees visiting blooming plants in an area covered by natural grasslands in the Vila Velha State Park was conducted from October, 2002, to October, 2003. A total of 1552 specimens belonging to 181 species were collected. These species are distributed in 58 genera, 24 tribes and 5 subfamilies. The visited plants belong to 113 species, in 72 genera and 38 families. Megachile, with 20 species, was the richest genus, while Ceratina was the most abundant native genus. Apis mellifera was the most abundant species, with 28% of all bees collected. Among the native species, Bombus atratus was the most abundant. Monthly richness and equitability varied along the year, March being the richest, and November, the most equitable. As plantas visitadas correspondem a 113 espécies, em 72 gêneros e 38 famílias. Megachile com 20 espécies foi o gênero mais rico e Ceratina o gênero mais abundante dentre os gêneros nativos. Apis mellifera foi a espécie mais coletada, correspondendo a 28% do total de indivíduos, e Bombus atratus foi a espécie mais abundante dentre as abelhas nativas. A riqueza e a equitabilidade nos meses foram variáveis, sendo março o mais rico e novembro o de maior equitabilidade. Apesar de tradicionalmente considerados parte das estepes sulinas, os campos de Vila Velha apresentam uma fauna de abelhas contendo várias espécies típicas de cerrado. O igual número de espécies entre as subfamílias Apinae e Halictinae também apontam para uma peculiaridade de sua fauna. Listas de abelhas e plantas coletadas são apresentadas em anexo.

Composition and diversity of bees (Hymenoptera) attracted by Moericke traps in an agricultural area in Rio Claro, state of São Paulo, Brasil

“…Specimens of the genus Oxaea is found only in Vila Velha State Park, Paraná, which is not considered an altered area (GONÇALVES & MELO, 2005). DUTRA & MACHADO (2001) collected visiting insects of Stenolobium stans (Bignoniaceae) in the city of Rio Claro, and recorded bees of Oxaea on the university campus, however the species was not found in an altered area in nearby Charqueada, state of São Paulo, probably due to the destruction of natural habitats, as discussed earlier.…”

Bees (Hymenoptera: Apoidea) and flowers in natural forest patches of southern Pantanal

“…In Brazil, studies on bee fauna have been conducted across a diversity of habitats: the Atlantic Forest (Wilms et al 1996, Alvesdos-Santos 1999, Ramalho, 2004, the Cerrado (Pedro & Camargo 1991, Silveira & Campos 1995, Viana et al 1997, Andena et al 2005, the Caatinga (Carvalho & Marchini 1999, Zanella 2000, Zanella & Martins 2003, Lorenzon et al 2003, Aguiar & Zanella 2005, in sand dunes (Alves-dos- Santos 1999, Viana & Kleinert 2005, in the southern grasslands (Schlindwein 1998, Alves-dos-Santos 1999, Gonçalves & Melo 2005, Gonçalves et al 2009) and in transitional areas of the Cerrado-Amazonia (Santos et al 2004). Most of these records are concentrated in the eastern part of the country.…”

Angiosperm flora used by meliponine guilds (Apidae, Meliponina) occurring at rainforest edges in the state of Ceará, Brazil

“…Among studies that report on food resources used by bees, including meliponines, we point out Cure et al (1992), Souza et al (1994), FariaMucci et al (2003), Gonçalves and Melo (2005), in southeastern and southern Brazil; and more recently Viana et al (1997), Ramalho and Silva (2002), Locatelli et al (2004), Milet-Pinheiro and Schlindwein (2008), Monteiro and Ramalho (2010), in northeastern Brazil.…”
