Study on Species and Behaviors of Flowervisiting Insects on Mussaenda pubescens

峨眉山自然保护区玉叶金花访花昆虫种类和访花行为研究（英文）

[Objective] This study aimed to understand the species and behaviors of flower-visiting insects on Mussaenda pubescens Ait.f.in the Mount Emei National Nature Reserve.[Method] The species,visiting frequency,visiting time and behaviors of flower-visiting insects on M.pubescens were studied by collection,identification and image capture.[Result] The flower-visiting insects on M.pubescens in the Mount Emei covered total 26 species with 21 species from Lepidoptera,2 species from Hymenoptera,and 3 species from Diptera.Thus,Lepidoptera were the main group of pollinators for c in the Mount Emei National Nature Reserve.The daily activity rhythms of Lepidoptera,Hymenoptera and Diptera showed different characteristics,and they were characterized by single-peak type and double-peak type.[Conclusion] This study will provide certain theoretical basis for studies on the diversity of flower-visiting insects on plants in the Mount Emei National Nature Reserve.

[目的]了解国家自然保护区峨眉山的玉叶金花植物访花昆虫种类及其行为。[方法]通过采用捕捉、鉴定、图像采集等方法,对玉叶金花访花昆虫的种类、访花频率、访花时间和访花行为等进行了研究。[结果]峨眉山自然生长的玉叶金花主要访花昆虫共计26种,其中鳞翅目(Lepidoptera)、膜翅目(Hymenoptera)、双翅目(Diptera)的主要访花昆虫分别为21种、2种和3种,鳞翅目(Lepidoptera)是玉叶金花主要的访花昆虫。鳞翅目(Lepidoptera)、膜翅目(Hymenoptera)、双翅目(Diptera)的访花昆虫日活动规律的高峰期出现有一定交错,表现有双峰和单峰二种类型。[结论]为自然保护区内植物访花昆虫的多样性研究提供了理论依据。
