Vespas sociais Polistinae e a eficiência de armadilhas atrativas em parques municipais

Abstract

The diversity and abundance of social wasps are influenced by several environment factors such as the quality and quantity of available resources, and anthropized areas generally have lower richness and abundance when compared to areas with natural vegetation. In this sense, our objective was to evaluate the diversity of social wasps and the efficiency of attractive traps in municipal parks. The collections were carried out during one year using attractive traps base on sardines, honey and passion fruit. A total of 567 individuals of 15 species were collected, with the genera Polybia and Mischocyttarus being the most diverse, representing 53.55% of the total species. The most abundant species was Polybia sericea, with 25 individuals (46.73%), followed by Polybia paulista, with 85 individuals (14.99%). The Shannon-Wiener and dominance index were 5.89 and 3.79 respectively, indicating high species diversity in the locations. 50 Regarding the efficiency of attracting baits, sardines were the least attractive (n=80), followed by honey baits (n=223) and then by passion fruit (n=264). The non-metric multidimensional scaling showed that the most similar areas were the Rego D’água and Antenor Martins parks due to the predominance of the species P. sericea. Thus, our results help to understand the species that are suitable for anthropic environments, requiring further studies on the dynamics and ecology of social wasps in urban areas.
