| As vespas integram a comunidade de visitantes florais e podem constituir uma parcela representativa dos polinizadores. Por este motivo, objetivou-se conhecer e analisar a preferência floral das espécies de Vespidae, bem como investigar o uso de recursos florais por estas vespas. Foram realizadas coletas entre o período de 2001 a 2008 em diferentes localidades do Estado do Rio Grande do Sul (Estrela Velha, Santa Cruz do Sul, São Francisco de Paula e Sinimbu), entre 08:00 a 17:00 horas, utilizando redes entomológicas para a captura dos vespídeos visitando flores. Os espécimes coletados foram depositados na Coleção Entomológica de Santa Cruz do Sul (CESC). Coletou-se 1.483 indivíduos alocados em 73 espécies de vespas, sendo que 78,9% são Polistinae (30... |

| Abstract Diptera is a megadiverse order, reaching its peak of diversity in Neotropics, although our knowledge of dipteran fauna from this region is grossly lacking. This applies even to the most studied families, such as Drosophilidae. Despite its prominence, most aspects of the biology of these insects are still poorly understood, especially those linked to natural communities. Field studies on drosophilids are highly biased towards fruit-breeding species. Flower-breeding drosophilids, however, are worldwide distributed, especially in tropical regions, although being mostly neglected. The present paper shows the results of a biodiversity inventory of flower-breeding drosophilids carried out in several localities in Brazil, based on samples of 125 plant... |

| Studies were carried out with Lagerstroemia speciosa Pers. on floral reproductive systems, diversity and constancy of visiting insects at different hours of day, the behaviour of these insects at the flowers and the influence of these environmental factors in relation to their visits. The fenology, anthesis and others particularity of this vegetal species was studied. A great diversity of insects was verified visiting the flowers with the predominance of bees. The most frequent and constant species encountered were: Nannotrigona testaceicornis (Lepeletier, 1836) (40,2%), Tetragonisca angustula (Latreille, 1811) (16,9%), Apis mellifera Linnaeus, 1758 (11,8%), Plebeia droryana (Friese, 1900) (9,1 %) e Exomalopsis fulvofasciata (Smith, 1879) (8,5%).
