Alexsei Zachvatkin
Aleksei Alekseevich Zachvatkin (Алексея Алексеевича Захваткина) (until 1931 with the surname Jasykov or Yazykov) (1 December 1905 - 14 December 1950) was a Russian entomologist and acarologist who worked on leafhoppers and mites. Aleksei was born in a Russian noble family in Ekaterinburg and grew up in Montreux, Switzerland, educated by private tutors. The family moved to Moscow just before World War I and he went to study at the State University of Moscow. An interest in natural history led to work at the university herbarium and then at the zoological museum. He took an interest in the cicadas but the October revolution of 1917 and his wealthy background meant that he could not join university. He however attended some classes informally and studied painting. In 1926 he joined the Central Asian Institute of Plant Protection as an assistant and travelled on several expeditions. Among his discoveries were of hypermetamorphosis in the Meloidae and Bombyli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acarology
Acarology (from Ancient Greek /, , a type of mite; and , ) is the study of mites and ticks, the animals in the order Acarina. It is a subfield of arachnology, a subdiscipline of the field of zoology. A zoologist specializing in acarology is called an acarologist. Acarologists may also be parasitologists because many members of Acarina are parasitic. Many acarologists are studying around the world both professionally and as amateurs. The discipline is a developing science and long-awaited research has been provided for it in more recent history.

Hypermetamorphosis
Hypermetamorphosis, or heteromorphosis,P.J. Gullan & P.S. Cranston. 2010. The Insects: An Outline of Entomology, 4th Edition. Wiley-Blackwell. is a term used in entomology that refers to a class of variants of holometabolism, that is to say, complete insect metamorphosis, but where some larval instars are distinct from each other. Description Hypermetamorphosis, as the term normally is used in entomology, refers to a class of variants of holometabolism. In hypermetamorphosis some larval instars are functionally and morphologically distinct from each other. The general case in holometabolous insects such as flies, moths, or wasps, is that all larval stages look similar, growing larger as the insect matures. In hypermetamorphic insects however, at least one instar, usually the first, differs markedly from the rest. In many hypermetamorphic species, the first instars are numerous, tiny, very mobile larvae that must find their way to a food source. The general term for a mobi ...

Blister Beetle
Blister beetles are beetles of the family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. About 7,500 species are known worldwide. Many are conspicuous and some are aposematically colored, announcing their toxicity to would-be predators. Description Blister beetles are hypermetamorphic, going through several larval stages, the first of which is typically a mobile triungulin. The larvae are insectivorous, mainly attacking bees, though a few feed on grasshopper eggs. While sometimes considered parasitoids, in general, the meloid larva apparently consumes the immature host along with its provisions, and can often survive on the provisions alone; thus it is not an obligatory parasitoid, but rather a facultative parasitoid, or simply a kleptoparasite. The adults sometimes feed on flowers and leaves of plants of such diverse families as the Amaranthaceae, Asteraceae, Fabaceae, and Solanaceae. Cantharidin, a poisonous chemical that causes bl ...

Bombyliidae
The Bombyliidae are a family of flies, commonly known as bee flies. Adults generally feed on nectar and pollen, some being important pollinators. Larvae are mostly parasitoids of other insects. Overview The Bombyliidae are a large family of flies comprising hundreds of genera, but the life cycles of most species are known poorly, or not at all. They range in size from very small (2 mm in length) to very large for flies (wingspan of some 40 mm).Hull, Frank Montgomery, Bee flies of the world: the genera of the family Bombyliidae Washington, Smithsonian Institution Press 1973 . Downloadable from: https://archive.org/details/beefliesofworl2861973hull When at rest, many species hold their wings at a characteristic "swept back" angle. Adults generally feed on nectar and pollen, some being important pollinators, often with spectacularly long proboscises adapted to plants such as ''Lapeirousia'' species with very long, narrow floral tubes. Unlike butterflies, bee flies hold t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trofim Lysenko
Trofim Denisovich Lysenko (russian: Трофим Денисович Лысенко, uk, Трохи́м Дени́сович Лисе́нко, ; 20 November 1976) was a Soviet agronomist and Pseudoscience, pseudo-scientist.''An ill-educated agronomist with huge ambitions, Lysenko failed to become a real scientist, but greatly succeeded in exposing of the “bourgeois enemies of the people.” From such a “scion” who was “grafted” to the Stalinist totalitarian regime “stock”, impressive results could have been expected—and were indeed achieved.'' He was a strong proponent of Lamarckism, and rejected Mendelian inheritance, Mendelian genetics in favour of his own idiosyncratic, Pseudoscience, pseudoscientific ideas later termed Lysenkoism. In 1940, Lysenko became director of the Institute of Genetics within the Soviet Union, USSR's Russian Academy of Sciences, Academy of Sciences, and he used his political influence and power to suppress dissenting opinions and discre ...

The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years.
