Rhinocyllus Conicus
''Rhinocyllus conicus'' is a species of true weevil. It is best known as a controversial agent of biological pest control which has been used against noxious thistles in the genera ''Carduus'', ''Cirsium'', ''Onopordum'', and ''Silybum''. The adult weevil is black and covered in a thin black and yellowish mottled coat of hairs. It is a short-snouted beetle up to 6 millimeters in total body length. The female lays over 100 eggs on or near the bracts of the thistle flower head. She covers the eggs with masticated plant tissue to protect them from predators. When the white larva emerges from its egg it burrows into the flower head and feeds on the flower parts and developing seeds. As it grows it deposits frass and chewed plant tissue on the walls of its chamber, producing a rigid protective shell in which it will pupate. Pupation takes up to two weeks and when the weevil emerges as an adult it remains inside the chamber for a few more weeks before tunneling out of the plant. Damag ...

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] |
Ernst Friedrich Germar
Ernst Friedrich Germar (3 November 1786 – 8 July 1853) was a German professor and director of the Mineralogical Museum at Halle. As well as being a mineralogist he was interested in entomology and particularly in the Coleoptera and Hemiptera. He monographed the heteropteran family Scutelleridae. In 1845, he was elected a foreign member of the Royal Swedish Academy of Sciences. Published works Amongst Germar's publications are: *Species Cicadarium enumeratae et sub genera distributae. ''Thon's Entomologisches Archiv''. (2)2: 37–57, pl. 1 (1830). *Observations sur plusieurs espèces du genre Cicada, ''Latr. Rev. Entomol. Silbermann'' 2: 49–82, pls. 19-26 (1834). *Ueber die Elateriden mit häutigen Anhängen der Tarsenglieder. Z. Entomol. (Germar) 1: 193-236 (1839) (1839). *Bemerkungen über Elateriden. ''Z. Entomol.

Curculionidae
The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae. They include the bark beetles as the subfamily Scolytinae, which are modified in shape in accordance with their wood-boring lifestyle. They do not much resemble other weevils, so they were traditionally considered a distinct family, Scolytidae. The family also includes the ambrosia beetles, of which the present-day subfamily Platypodinae was formerly considered the distinct family Platypodidae. Description Adult Curculionidae can be recognised by the well-developed, downwards-curved snout (rostrum) possessed by many species, though the rostrum is sometimes short (e.g. Entiminae). They have elbowed antennae that end in clubs, and the first antennal segment often fits into a groove in the side of the rostrum. The body tends to be robus ...

Margarita Ervandovna Ter-Minassian
Margarita Ervandovna Ter-Minassian (russian: Маргарита Ервандовна Тер-Минасян; 16 May 19109 April 1995) was a Soviet entomologist and specialist for weevils (Curculionoidea) and seed beetles (Bruchinae). Her name is sometimes transcribed as Ter-Minasian or Ter-Minasyan. Korotyaev, B.A. On the 100th anniversary of Margarita Ervandovna Ter-Minassian. Entmol. Rev. 90, 951–953 (2010). https://doi.org/10.1134/S0013873810070110 Biography Ter-Minassian was born in the German city of Leipzig, while her father was staying there for education. She got her secondary education in Echiadzin, and was a student at Yerevan State University from 1926. After graduating, she continued her education in 1932 at the Zoological Institute of the USSR Academy of Sciences in Leningrad. She published more than 170 scientific works, also describing many new species. She is mostly known for her two monographs on weevils of the subfamily Lixinae Lixinae is a subfamily of tr ...

Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management, nature reserves, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introduced as ornamental plants for horticultural use. Some "noxious weeds", such as ragwort, produce copious amou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
