本文描述了三种蚜虫--山毛榉、云杉根蚜和苹果绒茧蜂的蜡腺结构细节和分泌蜡的物理形态。这些腺体由大量增大的表皮细胞组成，其下方有一层修改过的角质层，形成了独特的蜡腺板。分泌蜡以细丝的形式从角质层中排出，这些细丝在每个表皮细胞上方的角质层中的排列产生了在每个物种中发现的独特的蜡丝--中空的、实心的或蜂窝状的。据推测，分泌蜡的主要作用是防止蚜虫被自己分泌的蜜露和群体中其他成员的蜜露污染。其他被考虑的次要作用包括：隔离个体小气候；保护免受真菌、寄生虫和天敌的伤害；防水和防冻。
The structural details of wax glands and the physical form of the secreted wax is described for the apterae of three aphid species-beech woolly aphid, spruce root aphid and woolly apple aphid. The glands are composed of greatly enlarged epidermal cells underlying a modified cuticle that forms distinctive wax gland plates. Secreted wax in the form of threads passes out of the cuticle as filaments, the arrangement of these filaments in the cuticle above each epidermal cell gives rise to the distinctive wax skein found in each species-hollow, solid or honeycombed. It is suggested that the primary role of the secreted wax is to prevent the aphids becoming contaminated by their own secreted honeydew and that of other members of the colony. Other secondary roles considered include: individual microclimate isolation; protection from fungi, parasites and predators; waterproofing and frost protection.
