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

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。

Study on Species and Behaviors of Flower-visiting Insects on Mussaenda pubescens

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 behav-iors of flower-visiting insects on M. pubescens were studied by col ection, identifica-tion 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 pol inators for c in the Mount Emei National Nature Reserve. The daily ac-tivity rhythms of Lepidoptera, Hymenoptera and Diptera showed different characteris-tics, and they were characterized by single-peak type and double-peak type. Con-clusion] This study wil provide certain theoretical basis for studies on the diversity of flower-visiting insects on plants in the Mount Emei National Nature Reserve.
