- 摘要:
- 勋章菊花大色艳属于典型的虫媒花,为探究勋章菊主要访花昆虫种类及其访花行为,选用5个勋章菊品种:星白、红纹、苏1、红?吻以及中国勋章菊以直接观察法进行观察研究。结果表明:在苏州地区勋章菊的主要传粉昆虫有9种,分属3目6科,传粉昆虫以蜂类和蝶类居多且不同种类的传粉昆虫访花行为不同;蜂类的访花时间与食蚜蝇类昆虫相比较短,但传粉效率高于食蚜蝇类;蜂类与蝶类相比,访花目的除了采集花蜜还有采集花粉;访花昆虫的形态结构与它的访花行为密切相关,单花受各类昆虫访问频率为9.1±6.2次?h-1;不同传粉昆虫之间存在互补关系,蜂类对勋章菊种群内小范围的传粉作用较大,而对较大范围内的传粉主要靠蝶类的访花活动。
- Abstract:
- Gazania rigens?L.is the typical entomophilous flowers with big size and bright-color,taking 5 different species :Xingbai,Hongwen,Su 1,Red?kiss and Zhongguo Xunzhangju as the experiment materials,the major species of pollinating insects and their flower-visiting behavior of Gazania rigens?L.was measured and recorded by the method of directing observation.The results showed that the major pollinating insects consisted of 9 species from 3 orders and 6 families.The main pollinators were bees and butterflies and different kinds of pollinators had different flower-visiting behavior; compared with butterflies,the bees collected not only nectar but also pollen; the morphological structure of the pollinating insects was closely related to flower-visiting behavior and the visit frequency of the single flower by all kinds of pollinators was 9.1 ± 6.2 times?h-1; complementary relationship existing between different pollinators,bees played greater role in a small range of Gazania rigens?L.population on pollination,while butterflies played greater role in a wide range of population.
