| Abstract: | Objective] This study was conducted to understand the species and quantity of flower-visiting insects in Xipu Forest Park, supplement the data of local flower-visiting insects, and fill the research gap of flower-visiting insects in the Lesser Hinggan Mountain. Method] The methods of route survey and sample plot survey were used to investigate the community of flower-visiting insects, and the method of net catching was used to collect flower-visiting insects and record relevant data. Results] A total of 1526 flower-visiting insects belonging to 79 species, 27 families and 9 orders were found. Among them, Lepidoptera was the most, accounting for 40.51％, while Odonata, Mantodea, Hemiptera and Thysanoptera are the least. The results showed that the insect diversity index and insect dominance index were higher in the flower cultivation area, the insect evenness index was highest in the lawn area, and the flower-visiting insects in arbor area and flower shrub area were more similar. Rosaceae had the most flower-visiting insects, followed by Compositae, Cruciferae and Leguminosae. Significance] The study provides scientific basis and data support for the rational development and utilization, biodiversity protection and sustainable development of forest parks. |
