Abstract

Occurrences of introduced and invasive pollinators are increasing worldwide. To predict the potential impacts of exotic bees on native ecosystems we need to understand their ecological interactions. Life history traits are fundamental for understanding ecological interactions and often help to explain the spread of exotic species. We conducted home-and-away comparisons of life history traits of the first invasive bee in Europe, the sculptured resin bee Megachile sculpturalis Smith 1853. We compiled information on nest architecture, offspring, natural enemies, body size and phenology using published literature, museum specimen, data from citizen science initiatives, field observations and reared specimen. Megachile sculpturalis uses a broad variety of nesting materials for brood cell construction, including even plastic at the exotic range. Body size at warm temperate climate was similar in the native and exotic ranges, but phenology shifted forward by about one month (28.9 ± 3.3 SE days) in the exotic ranges. The abundance of natural enemies was similar between native and exotic ranges but specialist enemies were missing in the exotic ranges. These trait shifts may be explained by founder effects or ecological filtering. The comparison of life history traits in native and exotic ranges sheds light on the ecological-evolutionary process of this quickly spreading species and provides a better understanding of invasion processes in solitary bees.

生活史特征的同地和异地比较表明了独居蜂Megachile sculpturalis的敌方释放和创始效应
在全球范围内,外来和入侵授粉昆虫的数量与日俱增。为了预测外来蜜蜂对本地生态系统的潜在影响,我们需要了解它们之间的生态相互作用。生命史特征是了解生态相互作用的基础,通常有助于解释外来物种的传播。我们对欧洲第一种入侵蜂--雕刻树脂蜂 Megachile sculpturalis Smith 1853 的生活史特征进行了同地和异地比较。我们利用已发表的文献、博物馆标本、公民科学活动数据、实地观察和饲养标本,汇编了有关巢穴结构、后代、天敌、体型和物候的信息。Megachile sculpturalis使用多种筑巢材料建造育雏室,在外来地区甚至包括塑料。在暖温带气候下,原生地和外来分布区的体型相似,但外来分布区的物候期提前了约一个月(28.9 ± 3.3 SE天)。原生地和外来地的天敌数量相似,但外来地缺少天敌。这些性状的变化可能是由于始祖效应或生态过滤作用造成的。原生地和外来地生活史特征的比较揭示了这一快速传播物种的生态进化过程,有助于更好地理解独居蜂的入侵过程。
