[ Method] The technique of paraffin section and the method of H-E staining were adopted to study the organizational structure of B. tabaci. The slices were examined and photographed under fluorescence microscope. [ Result] The coloring of H-E staining cells was good. Under 400 x conditions, the fat body, compound eyes, nucleus and muscle of B. tabaci were clear. [ Conclusion] The production method for paraffin section of B. tabaci was reliable, and the quality of slices was high.展开更多
