Abstract: 【Objective】 The experiment on morphological characteristics and microstructure of colleterial glands from Antheraea pernyi female silkmoths at different developmental stages was carried out to investigate the secretion mechanism of glue materials in the colleterial glands. 【Method】 The morphological characteristics and microstructure of colleterial glands were observed by anatomy and tissue paraffin section at different developmental stages and tissues. 【Result】 The colleterial glands became bigger with the development and reached the peak as the silkmoth emerges while the color of its inclusion was changed remarkably from transparent to blue black. Differences were observed in the microstructure between secretion section and reservoir section, the former showed the characteristics of secreting cells while the later did not. 【Conclusion】 Differences in morphological characteristics and microstructure of colleterial glands were observed at various stages and in different tissues.
