福建省油茶林主要传粉昆虫种类及访花行为

对福建省福州、泉州、龙岩、南平、宁德等地油茶林传粉昆虫及其访花行为进行了调查,结果表明:福建省油茶林中主要传粉昆虫有24种,分属于3目11科17属,其中膜翅目的昆虫种类最多,有11种;大分舌蜂是油茶最重要的传粉昆虫,其数量多,传粉效率高;传粉昆虫日活动时间在12∶00—14∶30出现高峰,昆虫个体数量平均占全天总数的70%左右;油茶传粉昆虫的访花行为因昆虫的访花目的不同而有较大差异,温度和光照是影响传粉昆虫数量、行为和频率的主要因素。

Investigation on the Pollination Insect Species and Their Foraging Behaviors on Camellia oleifera in Fujian Province

In this paper,the pollination insect species on Camellia oleifer was investigated in Fuzhou,Quanzhou,Longyan,Nanping,and Ningde Cities of Fujian Province,and their behaviors were studied.There were 24 pollination insect species belonging to 3 orders,11families and 17genus(the other 2 species were not identified to genus level),11 species of them were belonging to Hymenoptera.Colletes gigas was the most important pollination insect for C.oleifer,and it had a large amount and high pollinating efficient.There was a foraging activities peak of pollination from 12∶00 to 14∶30 during a day,about 70% of the pollinationg insects appeared during this period.The foraging behaviors of pollination insects were different depended on the aims of visiting the flowers.Temperature and light were the major factors which affected the amount,behaviors and frequency of pollination insects.
