title: Electron Microscope Studies on the Cuticle of Swarming and Nonswarming Tylenchorhynchus martini.
abstract: Studies on the structure of the cuticle of Tylenchorhynchus martini swarmers with electron microscopes revealed abnormal disruptive and eruptive morphological changes in most layers. Drastic effects of swarming on cuticular structure were reflected in the partial dissolution of cortical layer and matrix and in the irregular cracking of cortical sublayers in sublateral areas of the body. The occurrence of projections in the cortex was apparently unrelated to other changes. The structure of the cuticle of nonswarmers was intact and without any morphological changes.
