Characteristics of Floral Volatiles and Their Effects on Attracting Pollinating Insects in Three <i>Bidens</i> Species with Sympatric Distribution.

ABSTRACT: The transition from outcrossing to self-pollination is an evolutionary process in angiosperms. However, the changes in floral volatile composition during this process and their impacts on the behavior of pollinators are poorly understood. Therefore, this study investigated the potential differences in the floral volatile profiles and pollinator attraction capabilities of three invasive Bidens species. The results indicated that Bidens pilosa var. radiata (BH), which serves as a transitional species between facultative outcrossing and obligate outcrossing attracts a greater diversity and abundance of pollinators such as Apis cerana compared to the more self-compatible Bidens frondosa (DL) and Bidens pilosa var. pilosa (SY). Furthermore, a tot
