Trichoteras
''Trichoteras'' is a genus of gall-inducing Hymenopteran that has several species formerly classed as ''Andricus''. ''Trichoteras'' characteristics include antennae with 10 flagellomeres. An entomologist writing in 2018 stated that "is questionable that ''Heteroecus'' and ''Trichoteras'' should be synonymized with ''Andricus''" in regard to a proposed taxonomic reorganization of 2002. Ronald A. Russo in ''Plant Galls of the Western United States'' moves species like the Trichoteras vacciniifoliae, golden oak apple wasp from ''Andricus'' to ''Trichoteras'', while acknowledging the previously accepted binomials. William Harris Ashmead first defined this genus in 1897. List of ''Trichoteras'' species: * ''Trichoteras burnetti'' (formerly ''Andricus burnetti'') - woolly gall wasp * ''Trichoteras coquilletti'' (formerly ''Andricus coquilletti'') - little oak-apple gall wasp * ''Trichoteras frondeum'' (formerly ''Andricus frondeum'') - leafy bud gall wasp * ''Trichoteras rotundula'' (f ...

Trichoteras Coquilletti
''Trichoteras coquilletti'', formerly ''Andricus coquilletti'', also known as the little oak-apple gall wasp, is a fairly common species of cynipid wasp that produces galls on oak trees in North America. This wasp oviposits on the underside of the leaves of huckleberry oaks and canyon live oaks. The larval chamber is at the center of the gall, connected to the husk by slender, radiating fibers. See also * '' Trichoteras vacciniifoliae'' * Oak apple Oak apple or oak gall is the common name for a large, round, vaguely apple-like gall commonly found on many species of oak.

Trichoteras Vacciniifoliae
''Trichoteras vacciniifoliae'', formerly ''Andricus vacciniifoliae'', the golden oak apple wasp'','' is a species of gall-forming hymenopteran. The wasp creates a stem gall on host plants, namely huckleberry oaks and canyon live oaks. ''Andricus vacciniifoliae'' is native to the west coast of North America. Because of their colorful appearance and location on the plant, the galls are often mistaken for fruit. The larval chamber is at the center of the gall, connected to the husk by slender, radiating fibers.

Trichoteras Tubifaciens
''Trichoteras tubifaciens'', formerly ''Andricus tubifaciens'', also known as the crystalline tube gall wasp, is an uncommon species of cynipid wasp that produces galls 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 be ... on oak trees in Califoeni and Oregon in North America. This wasp oviposits on the midrib of the underside of the leaves of Oregon oaks. Up to 35 galls have been observed on a single leaf. Cream, yellow, red, and multicolor variants have been documented.

Andricus
''Andricus'' is a genus of oak gall wasps in the family Cynipidae. Life cycle As in all Hymenoptera, sex-determination in species of the genus ''Andricus'' is governed by haplodiploidy: males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. Many species in the genus alternate between an asexual generation and a sexual generation. Species The taxonomy of the genus ''Andricus'' is uncertain, with many of the approximately 375 species considered dubious. The following species are currently recognised in the genus ''Andricus'': * ''Andricus aciculatus'' Beutenmuller, 1909 * ''Andricus ahmeti'' Melika, Mutun & Dinç, 2014 * '' Andricus albicomus'' Weld, 1952 * ''Andricus albipes'' Hartig, 1840 * ''Andricus albobalani'' Weld, 1926 * ''Andricus alniensis'' Folliot, 1964 * ''Andricus amblycerus'' (Giraud, 1859) * ''Andricus amenti'' Giraud, 1859 * ''Andricus amphorus'' (Weld, 1926) * '' Andricus analis'' (Fonscolombe, 1 ...

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external Tissue (biology), 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 Herbivore, herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Gal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flagellomeres
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched) an ...

Heteroecus
''Heteroecus'' is a genus of gall wasps in the family Cynipidae Gall wasps, also incorrectly called gallflies, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this gener .... There are about seven described species in ''Heteroecus''.

Taxonomic
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from mer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
