利用光学显微镜观察腐食酪螨成螨外部形态特征。通过观察发现,腐食酪螨雄性成螨体长约300~440μm,表皮光滑,附肢4对呈淡棕色,各足均着生有刚毛和感器;胛内毛(sci)较胛外毛(sce)长;基节上毛(ps)膨大且有刺状侧突;背毛(d)4对,d1最短,d4最长;腹面可见圆形的肛吸盘和前肛毛(pra)各1对。雌螨体型较雄螨大,长约486~492μm,生殖区位于腹面第Ⅲ、Ⅳ基节之间,生殖毛3对;肛门达躯体末端,周围着生有肛毛(a)5对,肛后毛(pa)3对。通过对腐食酪螨成螨外部形态结构的观察为其科学分类提供了实验依据。
Observing the external morphological characteristics of Acaroid mites by using optical microscope. According to the observation, male mite body is about 300 ~ 440μm in length, the skin is smooth, the appendages 4 are light brown, and each foot has a bristle and sensor; sci is more than the extra-ocular hair ( dorsal hairs (d) 4 pairs, d1 the shortest, d4 longest; ventral surface can be seen round anal sucker and pre anus (pra) 1 Correct. Female mites body size larger than the male mite, about 486 ~ 492μm, the reproductive zone is located in the ventral third, Ⅳ basement, reproductive hair 3 pairs; anal reach the end of the body, surrounded by male anal hair (a) 5 pairs, anal After hair (pa) 3 pairs. The observation of the external morphology and structure of Acari mites on the mites provides an experimental basis for their scientific classification.
