摘要
对桂花访花昆虫种类、访花频率、访花时间、访花行为进行了初步研究。结果发现:桂花的主要访花昆虫有13科18种,隶属于膜翅目、鳞翅目、双翅目、鞘翅目、半翅目。其中鳞翅目共有7种,膜翅目6种,双翅目3种,鞘翅目、半翅目各1种。蜂类和食蚜蝇类访花频率高,数量大,为桂花主要的传粉昆虫。访花高峰期为桂花开花的盛花期,停留时间与传粉频率呈负相关关系。日活动规律为双峰型和单峰型,活动高峰期有一定交错。
The Osmanthus fragrans (Thunb.) Lour. (Oleaceae) flower visiting insect species and foraging behavior have important significance on the study of the pollination biology and breeding system evolution.Their visiting frequency,visit-ing duration and behavior were observed and recorded. The results are as followthe flowers are visited by 18 species of insects which belong to Hymenoptera, Lepidoptera,Diptera, Coleoptera and Hemiptera. And there are 7 kinds of insects belonging to Lepidoptera, 6 kinds of insects belonging to Hymenoptera,3 kinds of insects belonging to Diptera, 1 kind of insects belonging to Coleoptera and 1 kind of insects belonging to Hemiptera. The main pollinators are bees and flies,be-cause they have high visiting frequency and large number.The peak visiting frequency appeared in full bloom.The daily activities of the main pollinators appear single-peak type and double-peak type, which indicating a comple-mentary rela-tionship among the pollinators. The visiting frequency and landing time of main pollinating insects showed negative corre-lation.
