The Brazilian Cerrado, a hotspot and the largest savannah in the world, has been undergoing intense changes in land use for urbanization. The creation and maintenance of urban parks and public squares is one efficient biodiversity conservation strategy in urbanized landscapes. In this study, our objective was to evaluate the potential of urban parks with native vegetation for conservation of flower chafer beetles (Coleoptera: Cetoniinae), a beetle group usually used as a bioindicator in African landscapes, in Brazilian Cerrado. We sampled Cetoniinae beetles using aerial fruit-baited traps, every 2 wk from January to December 2014 in 10 areas of Cerrado in Aquidauana, MS, Brazil. We compared the species richness, abundance, biomass, and species composition between six 'natural reserve' areas (outside the urban matrix) and four 'urban park' areas (within the urban matrix), and identified specialist species of each habitat type. A total 508 individuals of nine species were captured. The abundance, species richness, and biomass were similar between natural reserve and urban park. However, species composition differed among the habitats. Gymnetis flava (Weber) was classified as an urban park specialist, while Euphoria lurida (Fabricius), and Hoplopyga liturata (Olivier) were classified as natural reserve specialists. Our results demonstrate that urban parks conserve the abundance, biomass and species richness of flower chafer beetles in the Brazilian Cerrado. In this context, our results suggest that the maintenance of the urban park with native vegetation can be an efficient strategy for the conservation of Cetoniinae beetles in the urban matrix in the Brazilian Cerrado.
巴西塞拉多是世界上的一个生物多样性热点地区和最大的热带稀树草原，其土地利用因城市化正在经历剧烈变化。创建和维护城市公园及公共广场是城市化景观中一种有效的生物多样性保护策略。在本研究中，我们的目标是评估巴西塞拉多地区具有原生植被的城市公园对花金龟（鞘翅目：花金龟亚科）的保护潜力，花金龟通常被用作非洲景观中的生物指示物种。2014年1月至12月期间，我们每隔两周在巴西马托格罗索州阿基多阿纳的10个塞拉多地区，使用空中水果诱饵陷阱对花金龟亚科甲虫进行采样。我们比较了六个“自然保护区”（城市基质之外）和四个“城市公园”地区（城市基质之内）之间的物种丰富度、丰度、生物量和物种组成，并确定了每种栖息地类型的特有物种。共捕获了9个物种的508个个体。自然保护区和城市公园之间的丰度、物种丰富度和生物量相似。然而，栖息地之间的物种组成有所不同。黄斑裸花金龟（Weber）被归类为城市公园特有物种，而黄粉 euphoria lurida（Fabricius）和麻点 hoplopyga liturata（Olivier）被归类为自然保护区特有物种。我们的结果表明，城市公园保护了巴西塞拉多地区花金龟的丰度、生物量和物种丰富度。在此背景下，我们的结果表明，维护具有原生植被的城市公园可以成为巴西塞拉多城市基质中保护花金龟亚科甲虫的有效策略。
