Characteristics of pollinating insect types and floral visiting behavior in wild fruit forests of the Ili Valley
[Objective]Ili Valley is the birthplace of many wild fruit trees,but in recent years,the ecosys-tems and biodiversity of wild fruit forests have been seriously damaged by pests and human interference.[Methods]Select four counties with the main distribution of wild fruit forests in the Ili Valley of Xinjing(Xinyuan,Gongliu,Huocheng and Yining),where wild fruit forests were mainly distributed and then their pol-linating insects were collected and identified.Secondly,the pollinating insects of two major flowering plants,wild apple flower and understory grass were investigated by targeted survey to evaluate their pollination efficien-cy.[Results]The study showed that 1485 numbers and 155 species of pollinating insects belonged to 6 orders and 39 families and 110 genera were found and recorded in the wild fruit forests of the Ili Valley,Andrena sp.,Lasioglossum sp.and Apis mellifera L.were the main pollinators.The similarity index showed that the pollina-tors in Yining were different from those in the other three sample sites;the study of the flower visiting behavior of Hymenoptera insects showed that the highest daily flower visiting rhythm of Apis mellifera occurred at 13:00-13:30.The pollination efficiency of wild Andrena sp.and Lasioglossum sp.were significantly higher than that of domestic Apis mellifera L.The wild fruit forests in the Ili Valley was an important source of wild fruit trees.[Conclusion]The clarification of pollinator resources and insect flower-visiting behavior in the Ili Valley,Xinjing.
