定位观测了紫藤的访花昆虫种类及觅食行为，用扫描电镜观察了花粉形态。结果表明：紫藤的主要访花昆虫为膜翅目的黄胸木蜂和意大利蜂，两者都有传粉行为，属传粉者。意大利蜂除有传粉行为外还有偷蜜行为。花粉在形态上表现出多型性：长球形(赤道观长椭圆形，极面观近三裂圆形)，三孔沟；三菱锥形(赤道观近三角形，极面观近三角形)，六孔沟；赤道观近三角形，极面观近菱形，四孔沟。外壁纹饰均为橘皮状。

The species of floral visitors and foraging behaviors were investigated by field observation, the morphological characteristics of pollens were also investigated by scanning electron microscopy. The main results were as follows:Common floral visitors of W. sinensis within observing time were species of Xylocopa appendiculata Smith and Apis mellifera ligustica Spinola, which belonged to the order of Hymenoptera. They both had legitimate visits as pollinators of W. sinensis. We also found nectar thieving behavior of Apis mellifera ligustica Spinola in the process of visiting. Three different morphological pollens were observed: prolate with tricolporate, elongated-elliptical in equatorial view and sub-3-lobed-circular in polar view;triangular pyramid with hexcolporate, subtriangular in equatorial view and polar view;and the third was tetracolporate, subtriangular in equatorial view and subrhombus in polar view. The extine orna-mentation of pollens described above were all like orange peel.
