Phytoptus
''Phytoptus'' is a genus of 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 evid ...s in the family Phytoptidae.

Phytoptus Avellanae
''Phytoptus avellanae'' is an acarine gall-mite species inducing big bud galls of up to across, sometimes slightly open, on the buds of hazel ('' Corylus avellana'') and on filbert ('' Corylus maxima''). Synonyms include ''Phytocoptella avellanae'', ''Eriophyes avellanae'', ''Calycophthora avellanae'', ''Phytoptus coryli'', ''Phytoptus pseudogallarum'', and ''Acarus pseudogallarum''. The mites are white, about 0.3 mm long, with numerous tergites and sternites. Two forms of ''P. avellanae'' exist, a gall causer and a vagrant form that has a more complex life-cycle and does not form galls. Common names include - DE: Haselnussgallmilbe, Haselnuss-Knospengallmilbe, ES: Badoc del avellano, FR: Phytopte du noisetier, IT: Eriofide del nocciolo, GB: Filbert bud mite, Hazelnut gall mite, TR: Fýndýk kozalak akarý. Galls Hazel big bud galls are generally common, resembling the big bud gall (''Cecidophyopsis ribis ''Cecidophyopsis ribis'' is an eriophyid mite which is best ...

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, 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 Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachnid
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 inse ...

Prostigmata
The Prostigmata is a suborder of mites belonging to the order Trombidiformes, which contains the "sucking" members of the "true mites" (Acariformes). Many species are notorious pests on plants. Well-known examples of prostigmatan plant parasites are species of the gall mites (Eriophyidae, e.g. the redberry mite '' Acalitus essigi''), Tarsonemidae (e.g. the cyclamen mite, '' Steneotarsonemus pallidus''), and the spider mites of the Tetranychidae (e.g. the two-spotted spider mite, ''Tetranychus urticae''). Other Prostigmata live as parasites on vertebrates (e.g. ''Demodex'' mites of the Demodecidae) or invertebrates (e.g. ''Polydiscia deuterosminthurus'' of the Tanaupodidae or the honeybee tracheal mite, ''Acarapis woodi'', of the Tarsonemidae). There are also some forms (e.g. Smarididae) that are predators of small invertebrates – including smaller Prostigmata – yet others have a more varied lifestyle (e.g. Tydeidae) or switch their food sources as they mature (e.g. Erythrae ...

Félix Dujardin
Félix Dujardin (5 April 1801 – 8 April 1860) was a French biologist born in Tours. He is remembered for his research on protozoans and other invertebrates. Biography In 1840 he was appointed professor of geology and mineralogy at the University of Toulouse, and during the following year was a professor of zoology and botany at Rennes. In regard to his educational background, Dujardin was largely self-taught, the son of a watchmaker. Dujardin worked with microscopic animal life, and in 1834 proposed that a new group of one-celled organisms be called Rhizopoda. He denied naturalist Christian Gottfried Ehrenberg's theory that microscopic organisms were "complete organisms" similar to higher animals, specifically noting that they had specialized structures unique to single-celled organisms, which meant that foraminifera he was studying was not, as his contemporaries believed it to be, a mollusk. In addition to his studies of microscopic life, he did extensive research on inve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
