薜荔传粉小蜂与非传粉小蜂的形态比较

 

【摘要】  桑科榕属(Ficus)植物都有隐花序,其瘿花中栖生着榕小蜂科(Agaonidae)昆虫。榕属植物的隐头花序为榕小蜂的生存提供食物和场所;榕小蜂为榕属植物传粉而效力。榕-蜂共生系统是桑科榕属植物与传粉榕小蜂专一互惠形成的生态学关系。但是 ,也有一些非传粉的小蜂出现在这个系统中 ,对榕-蜂共生系统可能产生较大的影响。薜荔(Ficus pumila L.)与薜荔榕小蜂(Wiebesia pumilae Wieb.)构成榕-蜂共生系统,佩妃延腹小蜂(Philotrypesis sp.)为薜荔的非传粉小蜂。本文研究薜荔榕小蜂与佩妃延腹小蜂的形态结构并对两者进行形态比较。根据传粉小蜂与非传粉小蜂的不同生理功能,研究小蜂在形态结构与生理功能上的关系。研究两者的关系可作为对其他榕属植物及其寄生昆虫作为一理论依据,在遗传学、进化学、生态学、形态学、生理学、分类学等方面上都具有重大意义,对进化史的重建,种界定和特征进化也有重要影响。

【关键词】 薜荔、薜荔榕小蜂、佩妃延腹小蜂、形态比较

BiLi pollination small bee and the form of bees pollinate small.
[in] moraceae banyan genera (Ficus) plants are implicit in the flower inflorescence, its gall a little bee habitat Agaonidae division (tree) insects.The secret of plants belong to banyans head for the tree having survival provide food and place, Ficus small bee for of plants belong to banyans pollination and effectiveness.Ficus - bees are symbiotic system of plants belong to banyans moraceae with little bees pollinate banyan with the ecology benefit form.However, there are also some small bees pollinated in this system, the system of banyan - bees can produce bigger impact.BiLi (Ficus pumila l.) and BiLi banyan small bee (Wiebesia pumilae Wieb) constitute the banyan - bees symbiotic system, little bee was delayed Philotrypesis (stomach) for BiLi sp of small bees pollinated.This study BiLi banyan with little bee was delayed the abdomen of morphological structure and form to them.With little bees pollinate according to the different small bees pollinate physiological function, the research on morphology and physiological function of the relationship.Research on the relationship between as other of plants belong to banyans and parasitic insects as a theoretical basis for genetics, chemistry, physiology and ecology, morphology, on the aspects of classification is of great significance to the reconstruction of history, and also have important influence on the evolution characteristics.
