【摘要】 对濒危植物柄扁桃(Amygdalus pedunculata)访花昆虫的种类、访花行为、访花频率和日活动规律进行了研究。结果表明:柄扁桃的访花昆虫有5目17科19属21种,其中传粉昆虫为3目11科13属15种,主要的传粉昆虫为黑颚条蜂(Anthophora melanognatha)、密林熊蜂(Bombus patagiatus)、大蜂虻(Bombylius major)、黄腿食蚜蝇(Syrphus ribesii)及红足隧蜂(Halictus rubicundus);主要传粉昆虫的日活动规律差异较大,活动高峰期彼此交错;黑颚条蜂具有体积大、携粉量大、小花停留时间短等特点,为柄扁桃传粉的效率最高,今后应加强其生物学、传粉生态学方面的研究。更多还原

【Abstract】 An investigation was conducted on the pollination insect species,their flowervisiting behaviors,and diurnal activity rhythm on endangered plant Amygdalus pedunculata.A total of 21 visiting insect species belonging to 5 orders,17 families,and 19 genera were recorded,among which,15 species belonging to 3 orders,11 families,and 13 genera were pollination insects.Anthophora melanognatha,Bombus patagiatus,Bombylius major,Syrphus ribesii and Halictus rubicundus were the main pollination insects.Their diurnal activity rhythms had greater difference,and their activity’s peaks staggered each other.Among the main pollination insects,A.melanognatha had the characters of large body size,short residence time,and carrying large amount of pollen,being the most efficient pollination insect on A.pedunculata,and thereby,the study of its biology and pollination ecology should be strengthened in future.更多还原
