Aculus gemmarum is a species of mite which causes galls on the buds of willows (Salix species). It was first described by Alfred Nalepa in 1892.
The buds are enlarged and hairy, and the mites are found between the small distorted leaves on Salix aegyptiac , S. aurita , S. babylonica , S. caprea , S. cinerea , S. elaeagnos , S. matsudana , S. repens (and possibly on Salix herbacea and Salix triandra ). [1] [2]
Aculus gemmarum has been found in Finland, France, Germany, Great Britain, Italy and Sweden. [1] [3]
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. They are microscopic mites and are yellow to pinkish white to purplish in color. The mites are worm like, and have only two pairs of legs. Their primary method of population spread is by wind. They affect a wide range of plants, and several are major pest species causing substantial economic damage to crops. Some species, however, are used as biological agents to control weeds and invasive plant species.
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. A few are economically significant pests, while others are useful as agents of biological pest control of invasive plants such as rush skeletonweed, creeping thistle, and field bindweed.
Aceria anthocoptes, also known as the russet mite, rust mite, thistle mite or the Canada thistle mite, is a species of mite that belongs to the family Eriophyidae. It was first described by Alfred Nalepa in 1892.
Aculus is a genus of mites, including the following species:
Phyllocoptes eupadi is a mite that chemically induces a pouch gall to develop as a sub-spherical distortion rising up from the upper surface of the lamina of leaves of blackthorn shrubs Prunus padus, Prunus spinosa and other Prunus species. Synonyms are Phytoptus padi Nalepa, 1890 and "Eriophyes padi ", non Eriophyes padi Domes, 2000.
Aceria fraxinivora, also known as the cauliflower gall mite and the ash key gall, causes the growths, known as galls, found on the hanging seeds or "keys" of the ash (Fraxinus) species.
Rabdophaga albipennis is a gall midge which forms galls on the shoots of white willow.
Aculus craspedobius is a species of mite which causes galls on the leaves of willows. It was first described by Alfred Nalepa in 1925.
Aculus magnirostris is a species of mite which causes galls on the leaves of willows. It was first described by Alfred Nalepa in 1892.
Aculus truncatus is a species of mite which causes galls on the leaves of purple willow. It was first described by Alfred Nalepa in 1892.
Aculus tetanothrix is a species of mite which causes galls on the leaves of willows. It was first described by Alfred Nalepa in 1889.
Aculus laevis is a species of mite which causes galls on the leaves of sallows. It was first described by Alfred Nalepa in 1892.
Aceria iteina is a species of mite which causes galls on the leaves of sallows and their hybrids. It was first described by Alfred Nalepa in 1925.
Phyllocoptes goniothorax is a species of mite belonging to the genus Phyllocoptes, which causes galls on the leaves of hawthorns. It was first described by Alfred Nalepa in 1889.
Eriophyes laevis is a gall mite which makes small, pimple-like galls on the leaves of alder. The mite was first described by the Austrian zoologist, Alfred Nalepa in 1889 and is found in Europe and North America.
Phyllocoptes malinus, also known as the apple leaf mite, is a species of mite belonging to the genus Phyllocoptes. It causes a gall, which is a swelling on the external tissues, on the leaves of apples. The mite is found in Europe and was first described by the Austrian zoologist Alfred Nalepa in 1892.
Acalitus plicans is an eriophyid mite which causes galls on beech. It is found in Europe and was first described by the Austrian zoologist Alfred Nalepa in 1917.
Acalitus stenaspis is an eriophyid mite which causes galls on beech. It is found in Europe and was first described by the Austrian zoologist Alfred Nalepa in 1891.
Acalitus calycophthirus is an eriophyid mite which causes big bud galls on birch twigs. It is found in Europe and was first described by the Austrian zoologist, Alfred Nalepa in 1891.
Epitrimerus trilobus is a gall mite in the family Eriophyidae, found in Europe. The mites feed on the leaves of elder (Sambucus species), causing abnormal plant growths known as galls. The mite was described by the Austrian zoologist, Alfred Nalepa in 1891.
