Tetrastichus Asparagi
''Tetrastichus'' is a genus of hymenopteran insects of the family Eulophidae. ''Tetrastichus planipennisi'' is a parasitoid of the emerald ash borer, a wood boring insect native to Asia which is an invasive species in North America. ''T. planipennisi'' is being evaluated as a biological control agent. Host species The genus ''Tetrastichus'' parasitizes many different species of Lepidoptera, such as ''Pyralis farinalis ''Pyralis'' is a genus of snout moths.

Tetrastichus Planipennisi
''Tetrastichus planipennisi'' is a parasitic non-stinging wasp of the family Eulophidae which is native to North Asia. It is a parasitoid of the emerald ash borer (''Agrilus planipennis'' Fairmaire, family Buprestidae), 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 searched since 2003 for its natural enemies in the wild leading to the discovery of several parasitoid wasps, including ''Tetrastichus planipennisi'' which is a gregarious endoparasitoid of EAB larvae on Manchurian Ash (''Fraxinus mandschurica'') and has been recorded to attack and kill up to 50 percent of EAB larvae. Life cycle ''Tetrastichus planipennisi'' parasitize EAB larvae by drilling through the bark and laying eggs on its host. The hatching parasitoid larvae feed and develop on the EAB larva, resulting in its death. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victor Motschulsky
Victor Ivanovich Motschulsky (sometimes Victor von Motschulsky, russian: link=no, Виктор Иванович Мочульский, 11 April 1810, in St. Petersburg – 5 June 1871, in Simferopol) was a Russian entomologist mainly interested in beetles. Motschulsky was an Imperial Army colonel who undertook extended trips abroad. He studied and described many new beetles from Siberia, Alaska, the United States, Europe, and Asia. While he tended to ignore previous work and his own work on classification was of poor quality, Motschulsky made a massive contribution to entomology, exploring hitherto unworked regions, often in very difficult terrain. He described many new genera and species, a high proportion of which remain valid. Travels Motschulsky's travels included: *1836 - France, Switzerland and the Alps, northern Italy and Austria *1839–1840 - Russian Caucasus, Astrakhan, Kazan and Siberia *1847 - Khirgizia *1850–1851 - Germany, Austria, Egypt, India, France, England, ...

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emerald Ash Borer
The emerald ash borer (''Agrilus planipennis''), also known by the acronym EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species. 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 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.

Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eulophidae
The Eulophidae are a large family of hymenopteran insects, with over 4,300 described species in some 300 genera. The family includes the genus ''Elasmus'', which used to be treated as a separate family, "Elasmidae", and is now treated as a subfamily of Eulophidae. These minute insects are challenging to study, as they deteriorate rapidly after death unless extreme care is taken (e.g., preservation in ethanol), making identification of most museum specimens difficult. The larvae of a very few species feed on plants, but the majority are primary parasitoids on a huge range of arthropods at all stages of development. They are exceptional in that they are one of two hymenopteran families with some species that are known to parasitize thrips. Eulophids are found throughout the world in virtually all habitats (one is even aquatic, parasitising water-penny beetles). Eulophids are separable from most other Chalcidoidea by the possession of only four tarsomeres on each leg, a small, st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera
Hymenoptera is a large order (biology), order of insects, comprising the sawfly, 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 Parasitoid wasp, 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 (biology), 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 language, Ancient Greek wikt:πτερόν, πτερόν (''pteron'') for wing. The Ancient Greek wikt:ὑμήν, ὑμήν (''hymen'') for membrane provides a plausible etymology for the term bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Cyril Layton Perkins
Robert Cyril Layton Perkins Royal Society, FRS (15 November 1866 – 29 September 1955) was a distinguished British entomologist, ornithologist, and naturalist noted for his work on the fauna of the islands of Hawaii and on Hymenoptera. He is not to be confused with his son John Frederick Perkins, also a hymenopterist. Life Perkins was born on 15 November 1866 at Badminton, Gloucestershire and was educated at King Edward VI Grammar School, St. Albans – his father, Rev Charles Perkins, was the headmaster – and at Merchant Taylors' School, Northwood, Merchant Taylors' School before obtaining a scholarship in Literae Humaniores, classics to Jesus College, Oxford in 1885. After two years of studying classics, he switched to reading Natural History, notwithstanding that he had not studied science at school, having been inspired to make the change by the lectures of Edward Bagnall Poulton, Edward Poulton on the colour of insects.

Alexander Henry Haliday
Alexander Henry Haliday (1806–1870, also known as Enrico Alessandro Haliday, Alexis Heinrich Haliday, or simply Haliday) was an Irish entomologist. He is primarily known for his work on Hymenoptera, Diptera, and Thysanoptera, but worked on all insect orders and on many aspects of entomology. Haliday was born in Carnmoney, Co. Antrim later living in Holywood, County Down, Ireland. A boyhood friend of Robert Templeton, he divided his time between Ireland and Lucca, where he co-founded the Italian Entomological Society with Camillo Rondani and Adolfo Targioni Tozzetti. He was a member of the Royal Irish Academy, the Belfast Natural History Society, the Microscopical Society of London, and the Galileiana Academy of Arts and Science, as well as a fellow of the (now Royal) Entomological Society of London. Alexander Haliday was among the greatest dipterists of the 19th century and one of the most renowned British entomologists. His achievements were in four main fields: desc ...
