Study on Flower Visiting Insects and Rule of Dominant Species in Parsley

【目的】明确香菜访花昆虫种类及优势种访花规律,为蜜源植物种类筛选提供理论依据。【方法】通过对四川地区香菜的访花昆虫种类进行调查和鉴定,并对优势种访花规律进行研究。【结果】香菜访花昆虫有38种,分属于6目19科,其中以双翅目、膜翅目、鞘翅目为主,捕食性食蚜蝇是香菜的优势访花昆虫。食蚜蝇早上9:00即开始在香菜花上活动,直至下午18:00,11:00-16:00为活动高峰期。【结论】香菜访花昆虫中天敌昆虫较多,是一种较优蜜源植物。

【Objective】The present paper aimed to clarify the flower-visiting insect species and visiting rule of dominant species in parsley,provide theoretical basis for the selection of nectar plant species.【Method】The insect species of parsley were investigated and identified,and the rhythm of dominant species was studied.【Result】There were 38 species of parsley flower-visiting insects,belonging to 19 families of 6 orders,among which Diptera,Hymenoptera and Coleoptera were the main species,and predacious hoverfly were the dominant species of parsley.Hoverflies began their activities on parsley flowers at 9:00 in the morning until 18:00 and 11:00-16:00 was the peak activity period.【Conclusion】There are many natural enemies in the flower visiting insects of parsley,and parsley is a good nectar plant.
