摘　　要：本文通过扫描电镜对寄生山羊体的山羊蠕形螨生活史各期颚体、足体和末体的超微结构观察。发现以下超微结构：一个圆锥状须乳突位于雌螨触须第２节背面；叶状背阳茎侧突和腹阳茎侧突竖立于阳茎同一基部；未受精雌螨船形阴门的一对瓣汇成纵线，雌螨交配后阴门半开，产卵后全部敞开。同时描述该螨的背基刺、锥状突、口下板、螫肢、基内叶、口孔、须爪和肛道等的超微结构。文中还讨论了锥状突、口下板、螯肢、基内叶、须爪和须乳突的功能。The present paper reports the scanning electron microscopy observation on theultrastructure of gnathosoma,podosoma and opisthosoma in the life cycle of Demodexcaprae. The following were founds A cone-shaped palpal papillae was at dorsal side of palpalsegment 2 in female;the lobe-like dorsal paramera and ventral paramera were on the base ofaedeagus;the boat-shaped vulva was covered by a pair of valves meeting along thelongitudignal line in virgin female; the genital was half opened after mating,and it was widely opened after laying egg. In addition,the ultrastructure of the supracoxal spines, theepistome,the hypostome, the chelicera,the coxal endite, the oral opening,the palpal clawsand the proctodeum were described;the morphology of the ultrastructure observed were briefly compared with those of D.canis,D.folliculorum and D. brevis; the function of theepistome,the hypostome,the chelicera,the coxal endite, the palpal claws and the palpalpapilla were discussed.
