采用超微结构技术研究了筋膜Dysdercus fasciatus signignoret雄性副生殖腺系统的结构和功能。腺体系统由一对mesadenia和射精管组成，其前端肿胀并包围着一个起源不明的腺体结构。每个中腺由大量腔室汇合的囊室组成。每个囊的上皮有一层细胞厚，由单核细胞和多核细胞两种细胞类型组成。中腺上皮细胞多核状态的起源和意义尚不清楚，但提示这种情况可能出现在成熟过程中，当有丝分裂完成时，细胞核在增加的细胞质团中继续繁殖，而细胞质团本身不分裂。
The structure and function of the male accessory reproductive gland system of the cotton stainer, Dysdercus fasciatus Signoret, was studied using ultrastructural techniques. The gland system is composed of a pair of mesadenia and an ejaculatory duct, whose anterior end is swollen and encloses a glandular structure whose origin is not clear. Each mesadene is composed of a large number of sacs whose lumina are confluent. The epithelium of each sac is one cell layer thick and is composed of two cell types, mononucleate and multinucleate cells. The origin and siginficance of the multinucleate condition in the mesadenial epithelial cells is not clear, but it is suggested that this condition might have arisen during maturation, when mitotic divisions are complete, but the nuclei continued to multiply within an increased cytoplasmic mass, which itself does not divide.
