摘　　要：白背飞虱Sogatella furcifera为水稻重要害虫,长翅型成虫能够远距离飞行迁移,扩散其危害的范围。本研究利用扫描电镜观察研究了长翅型白背飞虱雌成虫翅的超微特征,发现:前、后翅的翅面中间薄而边缘厚,翅中部到端部的边缘有叠起的褶皱,前翅背面翅面上均匀地分布着许多小刺状突起,长度为(3.07±0.48)μm,而后翅背腹两面均着生有许多小刺状突起。前翅的背面和腹面都存在毛形感器样结构,根据形态可分为TS-I和TS-Ⅱ两种:TS-I分布于腹面翅基部的翅脉处且与翅脉垂直,没有明显的基窝,数量为(4±1.41)根,长为(31.80±2.43)μm;TS-Ⅱ则分布于背面的翅脉上,数量为(5±1.41)根,长度为(57.25±21.84)μm,着生于有明显凹陷的基窝中。前翅腹面边缘以及翅脉处还分布有钟形感器样结构,数量为(5.00±3.46)个;另外还发现一种锥形感器样结构,位于前翅腹面边缘,数量为(21.00±4.36)个,长(8.25±2.09)μm。研究结果有助于从超微水平对白背飞虱翅的形态结构有个更深入的了解,进一步理解其迁飞扩散的能力,为寻找更好的防控措施打下基础。Sogatella furcifera is an important pest of rice.Long-winged adults can migrate over long distances and spread their harm.In this study,the ultramicroscopic characteristics of female adult planthopper with long wings were studied by scanning electron microscopy.The results showed that:The middle of the fore and hind wing surface is thin and the edge is thick.The edge of the middle to the end of the wing has folded.There are many small spines evenly distributed on the back wing surface of the forewing,the length is(3.07±0.48)μm,and there are many small spines on both sides of the hind wing.There were trichoid sensilla like apparatus on the dorsal surface and ventral surface of the forewing,which could be divided into TS-I and TS-Ⅱ.TS-I distributed in the ventral wing base and perpendicular to the ventral wing vein,and had no obvious basal fossa.The number of TS-I was 4±1.41,and the length was(31.80±2.43)μm.TS-Ⅱwas distributed on the dorsal vein of the wing,and the number of TS-Ⅱwas 5±1.41,the length was(57.25±21.84)μm,and the TS-Ⅱwas located in the basal fossae with obvious depression.Campaniform sensilla like apparatuses were also distributed in the ventral edge of the forewing and in the veins,and the number was 5.00±3.46.In addition,a basiconic sensilla like apparatus with 21.00±4.36 in number and(8.25±2.09)μm in length was found on the ventral edge of the forewing.The results of this study are helpful to further understand the morphological structure of the white back planthopper wing at the ultrastructural level,and understand its ability to migrate and spread,and lay a foundation for better prevention and control measures.
