Many plants hide their pollen due to their unique anther or corolla structure, forcing pollinators to use special methods, such as using acoustic resonance to spray pollen and achieve pollination. Most pollinators with this ability are bees (bee shock pollination), with the most representative being the bumblebee. The interaction patterns and mechanisms between pollinators and floral traits are significantly different in the process of pollination using bee vibration and using nectar as a reward. Little is known about the interaction patterns between pollinators and flower resources in bee induced pollination.

The upper cap of the corolla of some plants in the genus Artemisia forms a specialized and innovative trait (i.e. a twisted beak like structure) that wraps around the anthers, forcing pollinators such as bumblebees to release pollen in a buzzing manner. The Discipline Group of Plant Reproductive Ecology of Wuhan Botanical Garden, Chinese Academy of Sciences, took five non honey producing species of Pedicularis rostrata and three main pollinating bumblebees in the community as research objects, and through five consecutive years of field experiments, discussed the factors affecting bumblebees' preference for visiting flowers. Research has shown that when bumblebees can use the same frequency of bee tremors to visit different plants and obtain pollen, their preference for visiting flowers mainly depends on the abundance of flower resources, without specific species preferences; When bumblebees use different frequencies of bee tremors to visit the flowers of different plants, their preference for visiting flowers maintains a specific species preference, mainly for plants with higher pollen returns. This study elucidates the dependency patterns of the interaction between pollinators and flowering plants based on acoustic characteristics, enriching scientific understanding of the diversity of plant reproductive strategies.

The relevant research findings are titled "Bumblebees' flower preferences are associated with floral allowance and buzz frequency when buzz pooling co lowering plants" and published in Entomology Generalis. The research work is supported by the National Natural Science Foundation of China.
