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 deat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victor Motschulsky
Victor Ivanovich Motschulsky, sometimes Victor von Motschulsky ( Russian: Виктор Иванович Мочульский; 11 April 1810, St. Petersburg – 5 June 1871, 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, Belgium an ...

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by 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 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 insects play an important part in limiting the densities of potential pests. Biological control agents such as these include predators, parasitoids, pathogens, and com ...

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 ...

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 is 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 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 Thrips (Order (biology) , order Thysanoptera) are minute (mostly long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Entomologists have species description , described approximately 7,700 species. They fly on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...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 reach adulthood. 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 hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Cyril Layton Perkins
Robert Cyril Layton Perkins 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 before obtaining a scholarship in 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 Poulton on the colour of insects. His first publications in natural history journals came when he was still studying classics. He obtained a fourth-class degree in th ...

Alexander Henry Haliday
Alexander Henry Haliday (1806–1870, also known as Enrico Alessandro Haliday, Alexis Heinrich Haliday, or simply Haliday) was an Ireland, 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, County Antrim later living in Holywood, County Down, Holywood, County Down, Ireland. A boyhood friend of Robert Templeton, he divided his time between Ireland and Lucca, where he co-founded the La Società Entomologica Italiana, 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 Royal Microscopical Society, Microscopical Society of London, and the Galileiana Academy of Arts and Science, as well as a fellow of the (now Royal) Royal Entomological Society, Entomological Society of London.

Alfred Mathieu Giard
Alfred Mathieu Giard (8 August 1846 – 8 August 1908) was a French zoologist born in Valenciennes. He served as a professor of zoology at the Faculty of Sciences in Lille. He specialized in parasitology and the genus ''Giardia'' was named after him by Johann Künstler in 1882. Biography Giard was born in Valenciennes to grocer Alfred François Émile and Jeanne Henriette Mortamais. At an early age he became interested in plants and insects. In 1867, he began his studies of natural sciences at the École Normale Supérieure, followed by work as ''préparateur de zoologie'' at the laboratory of Henri de Lacaze-Duthiers (1821–1901) in Paris and later the teratologist Gabriel Dareste de la Chavanne. In 1872, he defended his doctoral thesis with a study on compound ascidians titled "''Recherches sur les ascidies composées ou synascidies''". From 1873 to 1882, he was ''professeur suppléant'' of natural history at the faculty of sciences in Lille, and in the meantime, was also ...
