作者于１９８２年在厦门仙人掌［Ｏｐｕｎｔｉａｄｉｌｅｎｉ（Ｋｅｒ）Ｈｏｗ］的根部发现一种形成胞囊的线虫，鉴定为仙人掌仙人掌皮线虫（Ｃａｃｔｏｄｅｒａｃａｃｔｉ），并对其胞囊、幼虫和卵进行了扫描电镜观察。扫描电镜下的主要特征是：胞囊突出的阴门锥背侧有一凹陷区，为雌虫的尾端。环膜孔，有阴门小齿。尾端与膜孔之间有２～３条表皮花纹。卵壳内壁密布大小不一的刻点。第二期幼虫头部中央椭圆形的唇盘与周围的６个唇是分开的，而两个侧背唇之间和两个侧腹唇之间也都是分开的，即各不愈合。头区有４条完整的环纹，环纹呈六边形。
A cyst-forming nematode was discovered in the roots of Opuntiadileni (Ker) How in Xiamen in 1982. It was identified as Cactoderacacti and its cysts, larvae and eggs were observed by scanning electron microscopy. The main feature under the scanning electron microscope is that there is a depressed area on the dorsal side of the female cone protruding from the cyst, which is the tail end of the female. Annular membrane hole with herniaceous teeth. There are 2 to 3 epidermal patterns between the tail end and the membrane hole. There are different moments in the size of the egg shell. The central ellipsoidal lip of the second larvae is separated from the surrounding six lips, and the two lateral lips and the two lateral lips are also separated, ie they do not heal. The head area has 4 complete ring patterns and the ring pattern is hexagonal.
