Leaf roll caused by Eriophyes granati (Canestrini & Massalongo) (pl. 68)

This is an interesting tubular leaf roll, which consists of a downward tight rolling and curling of the whole length of the leaf margin into a tube. Eventually the infested margin rolls toward the midrib but does not cover it. The mites are wrapped in the thickened turned-over leaf edge, where they live and reproduce inside the roll. In some plants, infestations are so heavy that nearly every young leaf is rolled, distorted, and twisted.
