Spathius Canadensis
''Spathius'' is a genus of doryctine wasps. The larvae of this genus of wasps feed on beetle larvae. They act as biological controllers of the certain pest beetles, such as ''Hylurgopinus rufipes'' and the emerald ash borer The emerald ash borer (''Agrilus planipennis''), also known by the abbreviation EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash trees, ash species (''Fraxinus'' spp.).

Spathius Galinae
''Spathius galinae'' is a parasitoid of the emerald ash borer. The known range of ''S. galinae'' extends from the Russian Far East to South Korea. It is currently approved for release in some areas of North America as part of a biological control program against the emerald ash borer. Beginning in early spring, adults lay eggs on host larvae by drilling into the tree with their ovipositor to reach the larva underneath the bark. The eggs hatch and consume the host larva. ''S. galinae'' larvae and pupae develop within the host gallery and emerge in approximately 35 days. Two to three generations occur per year. Prior to winter, pre-pupae halt development to enter diapause In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.Tauber, M.J., Tauber, C.A., Masaki, S.

Christian Gottfried Daniel Nees Von Esenbeck
Christian Gottfried Daniel Nees von Esenbeck (14 February 1776 – 16 March 1858) was a prolific Germany, German botanist, physician, zoologist, and natural philosopher. He was a contemporary of Goethe and was born within the lifetime of Carl Linnaeus, Linnaeus. He described approximately 7,000 plant species (almost as many as Linnaeus himself). His last official act as president of the German Academy of Natural Scientists Leopoldina was to admit Charles Darwin as a member. He was the author of numerous monographs on botany and zoology and majority of his best-known works deal with fungi. Biography Nees von Esenbeck was born in Schloss Reichenberg near Reichelsheim (Odenwald) in Hesse, Germany. He showed an early interest in science and, after receiving his primary education in Darmstadt, went on to the University of Jena and obtained his degree in biology (natural history) and medicine in 1800. He practiced as a physician for Francis I (Erbach-Erbach), but he had developed a gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spathius Agrili
''Spathius agrili'' is a parasitic non-stinging wasp of family Braconidae which is native to North Asia. It is a parasitoid of the emerald ash borer (''Agrilus planipennis'' Fairmaire), an invasive species which has destroyed tens of millions of ash trees in its introduced range in North America. As part of the campaign against the emerald ash borer (EAB), American scientists in conjunction with the Chinese Academy of Forestry began searching in 2003 for its natural enemies in the wild, leading to the discovery of several parasitoid wasp species, including ''Spathius agrili. S. agrili'' was discovered in Tianjin, China where it is a prevalent parasitoid of EAB larvae in stands of an introduced ash species ('' Fraxinus velutina)'', and an endemic ash species ('' Fraxinus mandshurica''). ''S. agrili'' has been recorded to attack and kill up to 90 percent of EAB larvae. This wasp is a gregarious ectoparasitoid, meaning it lays multiple eggs on the surface of its host, and the larva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spathius Thorpei
''Spathius thorpei'' is a species of parasitoid wasp belonging to the family Braconidae. The species was first described by Sergey A. Belokobylskij and Andrew D. Austin in 2013, and is endemic to New Zealand. Taxonomy The species was identified by Polish entomologist Sergey A. Belokobylskij and Australian entomologist Andrew D. Austin in 2013, based on a holotype collected by Stephen E. Thorpe in April 2003, from sedges in the Auckland Domain The Auckland Domain, also known as Pukekawa / Auckland Domain, is a large park in Auckland, New Zealand. Consisting of of land, Auckland Domain is the oldest park in the city. Located in the central suburb of Grafton, New Zealand, Grafton, the ..., Auckland, New Zealand. Belokobylskij and Austin named the species after Thorpe. Description Females of ''S. thorpei'' have a body length of , while males measure . The species has glabrous eyes, slender antennae, and is reddish brown in colour. The species can be differentiated by its d ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Emerald Ash Borer
The emerald ash borer (''Agrilus planipennis''), also known by the abbreviation EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash trees, ash species (''Fraxinus'' spp.). Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area. Outside its native range, it is an invasive species and is highly destructive to ash trees native to Europe and North America. Before it was found in North America, very little was known about the emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, and through the use of insecticides and biological control. History French ...

Braconidae Genera
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species. Classification The Braconidae are currently divided into about 47 subfamilies and over 1000 genera, which include ''Aerophilus'', ''Aleiodes'', ''Apanteles'', ''Asobara'', ''Bracon (wasp), Bracon'', ''Cenocoelius'', ''Chaenusa'', ''Chorebus'', ''Cotesia'', ''Dacnusa'', ''Diachasma'', ''Dimeris'', ''Microgaster'', ''Opius'', ''Parapanteles'', ''Phaenocarpa'', ''Spathius'', and ''Syntretus.'' These fall into two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the Labrum (arthropod mouthpart), labrum and the lower part of the Clypeus (arthropod anatomy), clypeus are concave ...

Biological Pest Control Wasps
Biology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, origin, evolution, and distribution of life. Central to biology are five fundamental themes: the cell as the basic unit of life, genes and heredity as the basis of inheritance, evolution as the driver of biological diversity, energy transformation for sustaining life processes, and the maintenance of internal stability (homeostasis). Biology examines life across multiple levels of organization, from molecules and cells to organisms, populations, and ecosystems. Subdisciplines include molecular biology, physiology, ecology, evolutionary biology, developmental biology, and systematics, among others. Each of these fields applies a range of methods to investigate biological phenomena, including observation, experimentation, and mathematical modeling. Modern biology is grounded ...
