Diversity of pollinating insects of early spring nectar plants in Northeast China
In order to reveal the relationship between nectar plants and pollinators,and protect and utilize pollinator resources scientifically.In this study,Salix,Corydalis and Anemone,the common nectar source plants in early spring in Northeast China,were selected as the research objects to investigate their pollination insect species and flower visiting behavior,and analyze the pollination insect species,dominant groups,diversity and flower visiting behavior of different nectar source plants.The results showed that a total of 726 pollinating insects were collected from early spring nectar plants in Northeast China,belonging to 53 species,14 families,and 5 orders,belonging to 53 species,14 families,and 5 orders.Among them,there were 35 species in 4 families of Hymenoptera,13 species in 5 families of Diptera,3 species in 3 families of Lepidoptera,1 species in 1 family of Homoptera,and 1 species in 1 family of Coleoptera.The results showed that the dominant pollinating insects of Salix were Apoidea,the dominant pollinating insects of Corydalis were Bumble,and the dominant pollinating insects of Anemone were Diptera.The diversity,evenness and abundance of Corydalis were the highest.Bees had the highest frequency of visiting Salix and staying time per flower,at 94.33 times and 18.90 seconds,respectively.Bombus had the highest frequency of visiting Corydalis and staying time per flower,at 94.33 times and 18.90 seconds,respectively.Bumbus had obvious honey stealing behavior when collecting Corydalis flowers.This behavior was conducive to the survival of other pollinating insects.In order to protect biodiversity and pollinating insect resources in Northeast China,we should combine the protection of nectar plants,replanting Salix,Corydalis and Anemone in early spring,and reasonably matching them to provide good food source and habitat for pollinating insects.
