Aceria ilicis causes felt-like galls (erinea), which are a patch of glandular hairs, caused by gall mites of the family Eriophyoidea. The bulge is 2–3 mm high on the upperside of the leaf of holm oak (also known as evergreen oak) and the depression below is several mm wide; there are usually several on a leaf.
Eriophyidae is a family of more than 200 genera of mites, which live as plant parasites, commonly causing galls or other damage to the plant tissues and hence known as gall mites. About 3,600 species have been described, but this is probably less than 10% of the actual number existing in this poorly researched family.
Aceria chondrillae [1] (chondrilla gall mite, skeletonweed gall mite) is a gall-forming deuterogynous eriophyid mite. It is often used as a biological control of the noxious weed Chondrilla juncea (rush skeletonweed), [ 2 ] a highly competitive herbaceous perennial composite found in Europe, Asia, Australia and North America.
Eriophyes is a genus of mite that forms galls, mainly on the leaves of deciduous plants. Some are called blister mites. The blue butterfly Celastrina serotina has been reported to feed on these galls and also on the mites, making it one of the uncommon carnivorous Lepidoptera. [1] Whereas other mites have four paired legs, Eriophyes have only ...
Aceria is a genus of mites belonging to the family Eriophyidae, the gall mites.These tiny animals are parasites of plants.Several species can cause blistering and galls, including erineum galls. [1]
Vasates quadripedes, the maple bladder-gall mite, is an eriophyid mite in the genus Vasates, which causes galls on the leaves of silver maple (Acer saccharinum), red maple , and sugar maple (A. saccharum). [1] The gall is rounded, sometimes elongate, and has a short, thin neck. Typically, galls are 2–3 millimetres (0.079–0.118 in) in ...
[1] [2] [4] Almost every inflorescence may be involved, the reproductive capacity therefore being reduced, however some seeds may still develop normally amongst the galls. [ 2 ] The cause of the gall are mites, mainly female, the eggs being viable without fertilization.
Aceria baccharices, also known as the mulefat leaf-blister mite and formerly known as Eriophyes baccharices, is a species of arachnid native to North America that induces galls on two California willows, Baccharis salicifolia and Baccharis glutinosa. [1] [2] This mite was first described to science by Hartford H. Keifer in 1945. [3]
