Abstract
Rotylenchulus reniformis fed on modified pericyc1e tissue in cowpea roots. The feeding area extended six to fifteen cells on either side of the nematode head but a group of four to six cells closest to the nematode lips were obviously inter-connected by gaps in the radial walls, thus forming a functional unit (the feeding zone). The cell adjacent to the nematode lips (the feeding cell or initial syncytial cell) contained a feeding peg enclosing the nematode stylet. Opposite the stylet tip a hyaline tube (feeding tube) could be traced coiling helically in the feeding cell. Since the nematode head becomes immobile following establishment at a feeding site, the tube is thought to act as a filter through which the nematode may obtain cell solutes without cell particles that might block the stylet lumen.
