Eriophyes Inangulis
''Eriophyes inangulis'' is a mite that forms the alder vein angle gall. It develops in a chemically induced gall; a sub-spherical distortion rising up from the upper surface of the leaves of alder trees ''Alnus glutinosa ''Alnus glutinosa'', the common alder, black alder, European alder, European black alder, or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations whe ...'' along the midrib. Synonyms are ''Eriophyes laevis inangulis'', ''Phytoptus laevis'', and ''Cephaloneon pustulatum''. The physical appearance The gall's appearance on the upper surface is sub-spherical, smooth and may vary in colour from pale yellow-green to deep red. The adult mite lives on alder tree sap, sucked from the cell tissues. The galls cluster along the midrib in the angle of the veins. The wide opening and interior on the lower epidermis and is lined with large numbers of small hairs. Galls may be so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Nalepa
Alfred Nalepa (19 December 1856, in Werschetz – 11 December 1929, in Baden bei Wien) was an Austrian zoologist specializing in the field of acarology. He studied natural sciences at the University of Vienna, and from 1886 was associated with the ''Lehrerbildungsanstalt'' in Linz. In 1892 he returned to Vienna, where he was appointed professor of natural history at the ''Elisabethgymnasium''. He described many species in the field of acarology, and was the taxonomic authority of the gall mite family, Eriophyidae.

Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blandford Press
Blandford Forum ( ), commonly Blandford, is a market town in Dorset, England, sited by the River Stour about northwest of Poole. It was the administrative headquarters of North Dorset District until April 2019, when this was abolished and its area incorporated into the new Dorset unitary authority. Blandford is notable for its Georgian architecture, the result of rebuilding after the majority of the town was destroyed by a fire in 1731. The rebuilding work was assisted by an Act of Parliament and a donation by George II, and the rebuilt town centre—to designs by local architects John and William Bastard—has survived to the present day largely intact. Blandford Camp, a military base, is sited on the hills north-east of the town. It is the base of the Royal Corps of Signals, the communications wing of the British Army, and the site of the Royal Signals Museum. Dorset County Council estimates that in 2013 the town's civil parish had a population of 10,610. The town ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology. In human pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing. Causes of plant galls Insects and mites Insect galls are the highly distinctive plant structures formed by some herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alnus Glutinosa
''Alnus glutinosa'', the common alder, black alder, European alder, European black alder, or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations where its association with the bacterium ''Frankia alni'' enables it to grow in poor quality soils. It is a medium-sized, short-lived tree growing to a height of up to 30 metres (98 feet). It has short-stalked rounded leaves and separate male and female flowers in the form of catkins. The small, rounded fruits are cone-like and the seeds are dispersed by wind and water. The common alder provides food and shelter for wildlife, with a number of insects, lichens and fungi being completely dependent on the tree. It is a pioneer species, colonising vacant land and forming mixed forests as other trees appear in its wake. Eventually common alder dies out of woodlands because the seedlings need more light than is available on the forest floor. I ...

Eriophyes Inangulis N - Lower Epidermis
''Eriophyes'' is a genus of acari that forms galls, specially on trees of the family Rosaceae. 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. Species Species include: * '' Eriophyes alniincanae'' Nalepa, 1919 * '' Eriophyes amelancheus'' Nalepa, 1926 * ''Eriophyes arianus'' (Canestrini 1890) * '' Eriophyes betulae'' * '' Eriophyes betulinus'' * '' Eriophyes bucidae'' * '' Eriophyes buxi'' * ''Eriophyes calcercis'' , purple erineum maple mite * ''Eriophyes calophylli'' * ''Eriophyes calycophthirus'' * ''Eriophyes canestrini'' * ''Eriophyes canestrinii'' * ''Eriophyes cerasicrumena'' , black cherry finger gall mite * '' Eriophyes chondrillae'' * ''Eriophyes condrillae'' , gall mites * '' Eriophyes crataegi'' * ''Eriophyes cupulariae'' * ''Eriophyes dentatae'' * ''Eriophyes dimocarpi'' , longan gall mite * ''Eriophyes diversi ...

Eriophyidae
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. Notable species Notable species in this family include: *''Abacarus hystrix'', the cereal rust mite *'' Abacarus sacchari'', the sugarcane rust mite *'' Acalitus essigi'', the redberry mite, which affects blackberries *''Aceria chondrillae'', the chondrilla gall ...

Animals Described In 1919
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms ...

Arachnids Of Europe
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult insects ...
