摘　　要：白蜡虫EricerusPela的马氏管由两条黄色膨泡串状的端管和一条公共管构成，通过公共管与消化道相连。端管和公共管细胞结构相似，都具有非胶原质的基膜，高度发达的基褶，长而致密的微绒毛，微绒毛无线粒体插入，细胞质中线粒体少，且随机分布。细胞质的绝大部分为两种矿质－尿酸颗粒结晶所占据，一种为不规则结晶，另一种为轮纹状结晶。白蜡虫马氏管可能发生了合胞化，其排泄方式可能是一种以滞留排泄为主，离子梯度排泄方式为辅的特有的排泄方式。The ultrastructure of Malpighian tubules of white wax scale, Ericerus pela Chavannes was studied in 1993~ 1994. The results are summarized as follows.According to our observation, Malpighian tubules of white wax scale consist of two yellow beaded distal tubules and one common tubule, which joins the gut. The structure of basal tubules and common tubule cells are similar. The Malpighian tubules of this insect possess non-collagen basement membrane, highly infolded basal foldings, and long and packed microvilli. There are 3 ~ 7 microtubules in each microvillus which carries out exocytosis.There are a few mitochondria distributing randomly and lots of ribosomes in the cytoplasm of Malpighian tubules. The cytoplasm is full of two sorts of mineral-uric acid concretions designated as laminated concretion and irregular concretion. The excretion pattern of Malpighian tubules of white wax scale is a special one, in which the store-excretion pattern is primary and the ion-gradient excretion pattern is secondary.
