Amblyomma Variegatum
''Amblyomma variegatum'', commonly known as the tropical bont tick, is a species of tick of the genus ''Amblyomma'' endemic to Africa. It has spread from its centre of origin to several countries, including the Caribbean islands, where it is known as the Senegalese tick (due to the suspected introduction of the tick from cattle imports from that country) and the Antigua gold tick. They are vividly coloured (especially the males) and have a substantial impact on livestock, primarily through their transmission of diseases. They are three-host hard ticks (where each life stage completes a blood meal on a particular host before dropping off and ecdysis) that have been found on a variety of domesticated species such camels, cattle, goats, sheep, dogs, and various species of wildlife. Control Control programmes have not fared as well as for ''Rhipicephalus'' (''Boophilus'') spp. due to the wider host range.

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

World Organisation For Animal Health
The World Organisation for Animal Health (WOAH), formerly the (OIE), is an intergovernmental organization coordinating, supporting and promoting animal disease control. Mission and status The main objective of the WOAH is to control epizootic diseases and thus to prevent their spread. Other objectives consist of: transparency, scientific information, international solidarity, sanitary safety, the promotion of Veterinary Services, food safety and animal welfare. It is recognized as a reference organisation by the World Trade Organization (WTO) and in 2018 had a total of 182 member states. Its newest member state is Saint Lucia. The WOAH maintains permanent relations with 45 other international and regional organisations and has Regional and sub-regional Offices on every continent. The WOAH does not depend on the UN system; its autonomy is both institutional and financial and its activities are governed by its own constitutional texts. Since its first General Session held in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animals Described In 1794
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...

Feedlot
A feedlot or feed yard is a type of animal feeding operation (AFO) which is used in intensive animal farming, notably beef cattle, but also swine, horses, sheep, turkeys, chickens or ducks, prior to slaughter. Large beef feedlots are called concentrated animal feeding operations (CAFO) in the United States and intensive livestock operations (ILOs) or confined feeding operations (CFO) in Canada. They may contain thousands of animals in an array of pens. Purpose and regulation The basic principle of the feedlot is to increase the amount of fat gained by each animal as quickly as possible; if animals are kept in confined quarters rather than being allowed to range freely over grassland, they will gain weight more quickly and efficiently with the added benefit of economies of scale. Most feedlots require some type of governmental approval to operate, which generally consists of an agricultural site permit. Feedlots also would have an environmental plan in place to deal with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corral
A pen is an enclosure for holding livestock. It may also perhaps be used as a term for an enclosure for other animals such as pets that are unwanted inside the house. The term describes types of enclosures that may confine one or many animals. Construction and terminology vary depending on the region of the world, purpose, animal species to be confined, local materials used and tradition. ''Pen'' or ''penning'' as a verb refers to the act of confining animals in an enclosure. Similar terms are kraal, boma, and corrals. Encyclopædia Britannica notes usage of the term "kraal" for elephant corrals in India, Sri Lanka, and Thailand. Australia and New Zealand In Australia and New Zealand a ''pen'' is a small enclosure for livestock (especially sheep or cattle), which is part of a larger construction, e.g. ''calf pen'', ''forcing pen'' (or yard) in sheep or cattle yards, or a ''sweating pen'' or ''catching pen'' in a shearing shed. In Australian and New Zealand English, a paddoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Annual Review Of Entomology
The ''Annual Review of Entomology'' is a peer-reviewed academic journal that publishes review articles about entomology, the study of insects. First published in 1956 from a collaboration between the Entomological Society of America and Annual Reviews, its longest-serving editors are Thomas E. Mittler (1967–1997) and May Berenbaum (1998–2018). As of 2022, it has a 2021 impact factor of 22.682. History In 1953, a committee within the Entomological Society of America examined the volume of literature published each year in the field and recommended that a journal be established that published review articles. The Entomological Society approached the nonprofit publisher Annual Reviews, which also agreed that there was a need for a review series in entomology. The ''Annual Review of Entomology'' published its first volume in 1956, making it the tenth title published by Annual Reviews. At first, the ESA remained involved with the operation of the journal and confirmed the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acaricide
Acaricides are pesticides that kill members of the arachnid subclass ''Acari'', which includes ticks and mites. Acaricides are used both in medicine and agriculture, although the desired selective toxicity differs between the two fields. Terminology More specific words are sometimes used, depending upon the targeted group: * "Ixodicides" are substances that kill ticks. * "Miticides" are substances that kill mites. *The term scabicide is more narrow, and refers to agents specifically targeting ''Sarcoptes''. *The term "arachnicide" is more general, and refers to agents that target arachnids. This term is used much more rarely, but occasionally appears in informal writing. As a practical matter, mites are a paraphyletic grouping, and mites and ticks are usually treated as a single group. Examples Examples include: * Permethrin can be applied as a spray. The effects are not limited to mites: lice, cockroaches, fleas, mosquitos, and other insects will be affected. * Ivermectin can ...

Livestock Tag
An ear tag is a plastic or metal object used for identification of domestic livestock and other animals. If the ear tag uses Radio Frequency Identification Device (RFID) technology it is referred to as an electronic ear tag. Electronic ear tags conform to international standards ISO 11784 and ISO 11785 working at 134.2 kHz, as well as ISO/IEC 18000-6C operating in the UHF spectrum. There are other non-standard systems such as Destron working at 125 kHz. Although there are many shapes of ear tags, the main types in current use are as follows: * Flag-shaped ear tag: two discs joined through the ear, one or both bearing a wide, flat plastic surface on which identification details are written or printed in large, easily legible script. * Button-shaped ear tag: two discs joined through the ear. * Plastic clip ear tag: a moulded plastic strip, folded over the edge of the ear and joined through it. * Metal ear tag: an aluminium, steel or brass rectangle with sharp points, cl ...
