长翅型白背飞虱雌成虫翅的超微特征OACSTPCD

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 plan-thopper 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 fore-wing,which could be divided into TS-I and TS-Ⅱ.TS-I distributed in the ventral wing base and perpen-dicular 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-Ⅱ was distributed on the dorsal vein of the wing,and the number of TS-Ⅱ was 5±1.41,the length was(57.25±21.84)μm,and the TS-Ⅱ was 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.
