Other Contributions: Observations of the Excretory Pore of the Female of Tylenchulus semipenetrans Cobb Through the Scanning Electron Microscope

Abstract

The variability of the "cuticular formations" around the excretory pore of the female of Tylenchulus semipenetrans described by Gutierrez (3) was studied through the Scanning Electron Microscope. It was concluded that these formations are simply accumulations of excretions.
