火红拟孔蜂采访植物及访花行为的研究

Studies on Interviewing Plants and Foraging Behavior of Hoplitis pyrrhosoma Wu.

火红拟孔蜂 (H oplitis pyrrhosoma Wu.)为荒漠地区的一种传粉昆虫 ,经野外调查和通过对其腹毛刷上所携带花粉的扫描电镜研究和鉴定 ,该蜂采访植物有四合木、木霸王、蝎虎霸王、匍根骆驼蓬、白刺、狭叶锦鸡儿、沙枣等 ,共 6科 1 1属 1 6种 .该蜂喜欢采访辐射对称、白色或浅黄色的花朵 ;不同时期、不同地点采访植物不同 ,采访不同结构的花其行为有别 ,极喜欢采访四合木 ;成虫活动期及访花行为与四合木花期物候和花形态结构及泌蜜特点存在协同适应关系 .气候对其活动及访花有明显的影响 .

Hoplitis pyrrhosoma Wu.is one pollination insect in the desert area. By investigating in the field and scanning pollen carrying on the bee′s abdomen brush with the electron microscope,results are shown that plants interviewed have Tetraena mongolica Maxim.,Zygophyllum xanthoxylon Maxim.,Zygophyllum mucronatum Maxim.,Peganum nigelastrum Bunge.,Nitraria sibirica Pall.,Nitraria tangutorum Bobr.,Nitraria roborowskii Kom.,Caragana stenophylla Pojark.,Elaeagnus angustifolia L. and so on,which belong to 6 Family,11 Genus,16 Species.The bee likes interviewing radiation symmetrical, white or light yellow flowers;it interviews plants differently in different periods and different places. Furthermore foraging behavior with difference of flower structure is different and it likes very much interviewing Tetraena mongolica Maxim. There exists the relation in coordination between the adult′s activity and the period of the flower,foraging behavior and the flower′s structure,excreting nectar time. Weather has obvious influence on its activity and foraging behavior.
