Many studies have evaluated and categorized the pollination systems of plants in different regions. These studies resulted in the definition of new pollination systems, such as that by small diverse insects (SDI). Although SDI systems are frequent in tropical communities, we know little about the species of plants and pollinators that compose these systems. This study synthesized knowledge of SDI systems through a systematic review of the literature, in order to characterize the composition of plants and pollinator species related to this pollination system. Most studies of SDI systems were carried out in tropical rainforest communities, and used a variety of terminologies and concepts. We found 362 plant species assigned to the SDI system, distributed in 76 families and 35 orders. These species are mainly trees and have inconspicuous greenish flowers, and most are hermaphroditic or dioecious. Few studies provided information on the composition of pollinators, which encompassed small and large insects; beetles, wasp, flies, and bees were the most frequent groups. We suggest adoption of the term “pollination system by diverse insects” instead of “small diverse insects.” We discuss conceptual aspects and questions for studies with this pollination system.

小型昆虫对授粉系统的回顾。

许多研究已经对不同地区植物的授粉系统进行了评估和分类。这些研究得出了新的授粉系统的定义，例如小型不同昆虫（SDI）的授粉系统。尽管SDI系统在热带社区中很常见，但我们对构成这些系统的植物和传粉媒介的种类知之甚少。这项研究通过系统地回顾文献，综合了SDI系统的知识，以表征与该授粉系统有关的植物和授粉媒介的组成。SDI系统的大多数研究都是在热带雨林社区中进行的，并使用了各种术语和概念。我们找到了分配给SDI系统的362种植物，分布在76个科和35个订单中。这些物种主要是树木，并具有不显眼的绿色花朵，并且大多数是雌雄同体或雌雄异株。很少有研究提供有关授粉媒介组成的信息，其中包括大小昆虫。甲虫，黄蜂，苍蝇和蜜蜂是最常见的人群。我们建议采用术语“不同昆虫的传粉系统”，而不是“小型不同昆虫”。我们讨论了有关授粉系统的概念方面和研究问题。
