Abstract:

In order to research species and numbers of Cherry pollinators. We used sample survey and netting in the fixed points to survey pollinators of Cherry flowering in the Shenwangpo Village and the Shi Village in Jiang County of Cherry major producing areas of Shanxi Province. The results showed that: (1) 3290 specimens were collected, through identification they belonged to 4 orders, 15 families, 26 species, Hymenoptera was 64.83%-74.81% of Cherry pollinators, Apidae was the major pollinators of Hymenoptera. (2) β diversity analysis showed that, pollinators community similarity coefficient was 0.63 at mountain area and plain area, along the changes of environmental gradient from mountain area to plain area, species showed a relative reducing trend. (3) peak times of insects collection activities was 9:00-11:00, according to the numbers of collected insects from many to few one day, they were sorted as fellows: Apidae, Andrenidae, Syrphidae and Anthophoridae, when the temperature was 10℃, insects began activities, Apidae was the earliest insect to begin out-nest activities.
