Syrphid flies (Diptera: Syrphidae) are a cosmopolitan group of flower-visiting insects, though their diversity and importance as pollinators is understudied and often unappreciated. Data on 1,477 Syrphid occurrences and floral associations from three years of pollinator collection (2017-2019) in the Southern Illinois region of Illinois, United States, are here compiled and analyzed. We collected 69 species in 36 genera off of the flowers of 157 plant species. While a richness of 69 species is greater than most other families of flower-visiting insects in our region, a species accumulation curve and regional species pool estimators suggest that at least 33 species are yet uncollected. In order to further the understanding of Syrphidae as pollinators in the Southern Illinois region, we produced a NMDS ordination of floral associations for the most common syrphid species. The NMDS did not sort syrphid species into discrete ecological guilds, and syrphid floral associations generally fit those predicted by traditional pollination syndromes. We also conducted a preliminary analysis of the pollen-carrying capacity of different syrphid taxa, which found several Eristalis species to carry pollen loads comparable to the European Honey Bee, Apis mellifera, and showed significant differences in the pollen-carrying capacity of various syrphid species. Notably, the extremely common genus Toxomerus and other small Syrphinae species carried very little pollen, while large and pilose Eristalinae species carried large pollen loads.

伊利诺伊州南部的 Syrphidae:多样性、花卉协会及其作为传粉媒介的功效的初步评估

Syrphid 苍蝇(双翅目:Syrphidae)是一个世界性的访花昆虫群,尽管它们作为传粉媒介的多样性和重要性尚未得到充分研究,而且往往未被重视。此处汇编和分析了美国伊利诺伊州南部伊利诺伊州地区三年传粉媒介收集(2017-2019 年)中 1,477 次蚜虫发生和花卉关联的数据。我们从 157 种植物的花朵中收集了 36 属 69 种。虽然 69 种物种的丰富度高于我们地区大多数其他访花昆虫科,但物种积累曲线和区域物种库估计表明,至少有 33 种物种尚未收集。为了进一步了解作为南伊利诺伊州地区传粉媒介的 Syrphidae,我们为最常见的食蚜蝇物种制作了花卉协会的 NMDS 排序。NMDS 没有将 syrpid 物种分类为离散的生态行会,并且 syrpid 花卉协会通常符合传统授粉综合征预测的那些。我们还对不同梅毒类群的花粉携带能力进行了初步分析,发现几种Eristalis 种携带的花粉量与欧洲蜜蜂Apis mellifera 相当,并且显示出各种梅毒类的携带花粉能力存在显着差异。 . 值得注意的是,极其常见的 Toxomerus 属和其他小型 Syrphinae 物种携带的花粉很少,而大而柔毛的 Eristalinae 物种携带大量的花粉。和 syrphid 花卉协会通常符合传统授粉综合征的预测。我们还对不同梅毒类群的花粉携带能力进行了初步分析,发现几种Eristalis 种携带的花粉量与欧洲蜜蜂Apis mellifera 相当,并且显示出各种梅毒类的携带花粉能力存在显着差异。 . 值得注意的是,极其常见的 Toxomerus 属和其他小型 Syrphinae 物种携带的花粉很少,而大而柔毛的 Eristalinae 物种携带大量的花粉。和 syrphid 花卉协会通常符合传统授粉综合征的预测。我们还对不同梅毒类群的花粉携带能力进行了初步分析,发现几种Eristalis 种携带的花粉量与欧洲蜜蜂Apis mellifera 相当,并且显示出各种梅毒类的携带花粉能力存在显着差异。 . 值得注意的是,极其常见的 Toxomerus 属和其他小型 Syrphinae 物种携带的花粉很少,而大而柔毛的 Eristalinae 物种携带大量的花粉。发现几种 Eristalis 物种携带的花粉量与欧洲蜜蜂 (Apis mellifera) 相当,并且显示出各种梅毒物种的花粉携带能力存在显着差异。值得注意的是,极其常见的 Toxomerus 属和其他小型 Syrphinae 物种携带的花粉很少,而大而柔毛的 Eristalinae 物种携带大量的花粉。发现几种 Eristalis 物种携带的花粉量与欧洲蜜蜂 (Apis mellifera) 相当,并且显示出各种梅毒物种的花粉携带能力存在显着差异。值得注意的是,极其常见的 Toxomerus 属和其他小型 Syrphinae 物种携带的花粉很少,而大而柔毛的 Eristalinae 物种携带大量的花粉。
