摘 要: 研究使用激光共聚焦显微镜(confocal laser scanning microscopy,CLSM)及透射电镜(transmission electron microscopy,TEM)对白背飞虱(Sogatella furcifera)消化道系统的超微结构进行观察。白背飞虱消化道由食道、前憩室、中肠和后肠组成。在结构上食道和前憩室属于前肠,肠壁细胞层薄,内容物较少;中肠肠壁细胞层较厚,微绒毛结构呈杆状,排列紧密,细胞核呈椭圆形,细胞分化程度较高;后肠与中肠相连,在形态上以两侧对称的一对马氏管作为分界线,后肠具有较大的肌肉层,肠壁细胞层有较多的线粒体等细胞器;直肠由多种类型的上皮细胞构成,细胞核相对于中肠较小。研究将为探究病毒在白背飞虱体内的侵染机制奠定理论基础。
关 键 词: 植物病理学;白背飞虱;消化道;组织形态学;超微结构

Abstract: The confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM) were used to study the morphology and ultrastructure of digestive system of white-backed leafhopper (Sogatella furcifera). The gross morphology of the alimentary canal consists of esophagus, anterior diverticulum, midgut and hindgut. Esophagus and anterior diverticulum belongs to the foregut and in which the intestines cell layer is thin, less contents, oval nucleus; peritrophic membrane is thicker, and the microvilli structure packs closely like rods; cell differentiation degree is high; there are a pair of malpighiantubules as a boundary between midgut and hindgut, and the hindgut has great muscle layer and more organelles such as mitochondria, rectum consists of typical epithelial cells, the nucleus is relative small. These results will lay a theoretical foundation for the study of viruses in the white-backed planthopper infection mechanism.
Key words: phytopathology; white-backed planthopper (Sogatella furcifera); alimentary canal; internal morphology; ultrastructure
