木茼蒿访花昆虫种类及优势种访花规律研究

Study on Flower Visiting Insects and Rule of Dominant Species in Argyranthemum frutescens

为明确木茼蒿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,通过对四川会理市、冕宁县、巴中市巴州区、邛崃市等地木茼蒿的访花昆虫种类进行调查和鉴定,并对会理市、冕宁县木茼蒿优势访花昆虫活动规律进行研究,共鉴定出木茼蒿访花昆虫55种,分属于8目26科,其中以双翅目、膜翅目、鞘翅目为主,多异瓢虫、黑带食蚜蝇和大灰食蚜蝇为木茼蒿的优势访花昆虫.晴天和阴天,从9:00至17:00,3种天敌昆虫一直在木茼蒿上活动.木茼蒿访花昆虫中天敌昆虫较多,是一种较优天敌昆虫诱集植物.

To clarify the species of flower-visiting insects and visiting regulation of dominant species in Argyranthemum frutescens,provide theoretical basis for the selection of nectar plant species.The insect species visiting marguerite daisy was investigated and identified,and the regulation of dominant species was studied.There were 55 species of marguerite daisy flower-visiting insects,belonging to 26 families of 8 orders,among which Diptera,Hymenoptera,and Coleoptera were the main orders,Adonia variegata(Goeze),Episyrphus balteatus De Geer and Syrphus corollae were the dominant species of flower visiting insects.In sunny and cloudy days,the natural enemy insects began their activities on Argyranthemum frutescens flowers from 9:00 in the morning until 17:00.There were many natural enemy insects in the flower visiting insects of marguerite daisy,and marguerite daisy is a better natural enemy insect attraction plant.
