Abstract	A light and electron microscope study of Corylus avellana L. vegetative buds infested with the eriophyoid mites, Cecidiophyopsis vermiformis Nal. and Phycoptella avellanae Nal., is reported. Descriptions are given of changes in infested stipule tissue. The nipple-like proliferations (enations) which arise on the infested stipule surface are covered by a protein-, lipid-rich epidermal layer. The amount of vascular tissue in the stipule increases with infestation. The differences between healthy and infested stipule are discussed with respect to the effect each has on mite success and on plant loss.
