Abstract
A survey carried out by us (unpublished) revealed the concomitant infestation of the citrus nematode, Tylenchulus semipenetrans Cobb, and the reniform nematode, Rotylenchulus reniformis Linford et Oliveira, on root samples of grapevine, Vitis vinifera L., in Egypt. Since the first is known as a serious pest of Vitis spp. (Seinhorst and Sauer, 1956; Sauer, 1969; Lamberti et al., 1976) and the second is reported present in the rhizosphere of grapevine (Dasgupta and Seshadri, 1971; Riad, 1974), we thought it would be useful to study the interaction of populations of the two nematodes on grape seedlings.
