Floral resources used by insects in a grassland community in Southern Brazil

Abstract: -(Floral resources used by insects in a grassland community in Southern Brazil). The goal of the present study was to identify plant species used as food source, the floral resources utilized, and the insects that visit flowers in a grassland community in southern Brazil. The study was carried out in an area of one hectare, located in a grassland formation in the Parque Estadual de Itapuã, State of Rio Grande do Sul, Brazil. The flowering pattern was seasonal, and richness and abundance of insects was higher d… Show more

“…Considering anthophilous fauna, the groups of insects recorded in the community were similar to those found in other vegetation types of cerrado (Aoki & Sigrist 2006), grasslands (Freitas & Sazima 2006;Pinheiro et al 2008) or anthropic habitats, such as eucalyptus plantations (Lopes et al 2007). In our study, the richest and most abundant groups, including bees, flies and wasps, were mainly potential pollinators of the sampled plant species.…”

“…Esses resultados são similares aos obtidos por Pinheiro et al (2008), em uma formação campestre no Parque Estadual de Itapuã, RS, com precipitação anual entre 1.100 e 1.300 mm, em que 41,5% das espécies vegetais ofereceram néctar; 21,6%, pólen; e 27,3%, néctar e pólen. No entanto, Nunes et al (1996) <1, pouco florida; <2, medianamente florida; <3, muito florida; e <4, abundantemente florida (Fournier, 1974).…”

“…Os levantamentos sobre a flora melífera com avaliação da disponibilidade e da época de floração das plantas são geralmente realizados pela observação direta da planta visitada pelas abelhas nativas ou africanizadas (Carvalho & Marchini, 1999;Marchini et al, 2001;Moreti et al, 2006;Pinheiro et al, 2008;Vieira et al, 2008), ou pela observação indireta por meio da análise do pólen apícola (Mendonça et al, 2008) e dos grãos de pólen presentes no mel (Mendonça et al, 2008;Sodré et al, 2008) ou na própolis (Santos et al, 2003).…”

“…Apesar da grande representatividade do grupo, poucos são os estudos acerca da ecologia da reprodução e polinização de Iridaceae. Destacamse os estudos que avaliaram a radiação dos sistemas de polinização de Iridaceae (Goldblatt & Manning 2006), a entomofauna visitante de Belamcanda chinensis (L.) Redouté (Vitali et al 1995) e os recursos florais utilizados por insetos em uma comunidade campestre no sul do Brasil (Pinheiro et al 2008).…”
