Furniture Beetle
The common furniture beetle or common house borer (''Anobium punctatum'') is a woodboring beetle originally from Europe but now distributed worldwide. In the larval stage it bores in wood and feeds upon it. Adult ''Anobium punctatum'' measure in length. They have brown ellipsoidal bodies with a prothorax resembling a monk's cowl. Life cycle The female lays her eggs in cracks in wood or inside old exit holes, if available. The eggs hatch after some three weeks, each producing a long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to . They come nearer to the wood surface when ready to pupate. They excavate small spaces just under the wood surface and take up to eight weeks to pupate. The adults then break through the surface, making a 1 mm to exit hole and spilling dust, the first visible signs of an infestation. After they emerge, the adults do not fee ...

Charles De Geer
Baron Charles de Geer (the family is usually known as De Geer with a capitalized "De" and is pronounced "de yer"); Finspång in Risinge 30 January 1720 – Stockholm 7 March 1778) was a Swedish industrialist and entomologist. Life De Geer, who came from a family with strong Dutch connections, grew up in Utrecht from the age of three. He returned to Sweden at the age of 19. He had inherited the entailed manor and important iron-works of Leufsta (Lövsta) in Uppland from his childless uncle and namesake and would substantially increased the wealth of the estate. Ever since he had received a present of some silk worms at the age of eight, he had an interest in entomology and became a respected amateur entomologist at an early age. His major work was the ''Mémoires pour servir à l'histoire des insectes'' (eight volumes, 1752-1778). He was elected a member of the Royal Swedish Academy of Sciences already in 1739, at the age of nineteen, and a corresponding member of the Fren ...

Heartwood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Anobiinae
Anobiinae is a subfamily of death-watch beetles in the family Ptinidae, with at least 45 genera. It was formerly considered a member of the family Anobiidae, but its family name has since been changed to Ptinidae. The larvae of a number of species tend to bore into wood, earning them the name "woodworm" or "wood borer". A few species, such as the common furniture beetle, '' Anobium punctatum'', are pests, causing damage to wooden furniture and house structures. Genera These 46 genera belong to the subfamily Anobiinae: * '' Actenobius'' Fall, 1905 * '' Allobregmus'' Español, 1970 * '' Anobichnium'' Linck, 1949 * '' Anobiopsis'' Fall, 1905 * '' Anobium'' Fabricius, 1775 * '' Anomodesmina'' Español, 1991 * '' Australanobium'' Español, 1976 * '' Belemia'' Español, 1984 * '' Cacotemnus'' LeConte, 1861 * '' Colposternus'' Fall, 1905 * ''Ctenobium'' LeConte, 1865 * '' Desmatogaster'' Knutson, 1963 * '' Endroedyina'' Español et Comas, 1991 * '' Euceratocerus'' LeConte, 1874 * '' F ...

Woodworm
A woodworm is the wood-eating larva of many species of beetle. It is also a generic description given to the infestation of a wooden item (normally part of a dwelling or the furniture in it) by these larvae. Types of woodworm Woodboring beetles with larvae commonly known as woodworm include: *Ambrosia beetles (weevils of the subfamilies Scolytinae and Platypodinae) *Woodboring weevils ('' Pentarthrum huttoni'' and '' Euophryum confine'') * Bark borer beetle or waney edge borer (''Ernobius mollis'') *Common furniture beetle (''Anobium punctatum'') *Deathwatch beetle (''Xestobium rufovillosum'') * House longhorn beetle (''Hylotrupes bajulus'') *Powderpost beetle (''Lyctus brunneus'') * Wharf borer (''Narcerdes melanura'') Manifestation Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes. The size of the holes varies, but are typically in diameter for the most common household species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Permethrin
Permethrin is a medication and an insecticide. As a medication, it is used to treat scabies and lice. It is applied to the skin as a cream or lotion. As an insecticide, it can be sprayed onto clothing or mosquito nets to kill the insects that touch them. Side effects include rash and irritation at the area of use. Use during pregnancy appears to be safe. It is approved for use on and around people over the age of two months. Permethrin is in the pyrethroid family of medications. It works by disrupting the function of the neurons of lice and scabies mites. Permethrin was discovered in 1973. It is on the World Health Organization's List of Essential Medicines. In 2020, it was the 427th most commonly prescribed medication in the United States, with more than 100thousand prescriptions. Uses Insecticide * In agriculture, to protect crops (a drawback is that it is lethal to bees) * In agriculture, to kill livestock parasites * For industrial and domestic insect control * In th ...

Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellent ...

Woodboring Beetle
The term woodboring beetle encompasses many species and families of beetles whose larval or adult forms eat and destroy wood (i.e., are xylophagous). In the woodworking industry, larval stages of some are sometimes referred to as woodworms. The three most species-rich families of woodboring beetles are longhorn beetles, bark beetles and weevils, and metallic flat-headed borers. Woodboring is thought to be the ancestral ecology of beetles, and bores made by beetles in fossil wood extend back to the earliest fossil record of beetles in the Early Permian (Asselian), around 295-300 million years ago. Ecology Woodboring beetles most often attack dying or dead trees. In forest settings, they are important in the turnover of trees by culling weak trees, thus allowing new growth to occur. They are also important as primary decomposers of trees within forest systems, allowing for the recycling of nutrients locked away in the relatively decay-resilient woody material of trees.

Cathedral Communications Limited
A cathedral is a church that contains the '' cathedra'' () of a bishop, thus serving as the central church of a diocese, conference, or episcopate. Churches with the function of "cathedral" are usually specific to those Christian denominations with an episcopal hierarchy, such as the Catholic, Eastern Orthodox, Anglican, and some Lutheran churches.New Standard Encyclopedia, 1998 by Standard Educational Corporation, Chicago, Illinois; page B-262c Church buildings embodying the functions of a cathedral first appeared in Italy, Gaul, Spain, and North Africa in the 4th century, but cathedrals did not become universal within the Western Catholic Church until the 12th century, by which time they had developed architectural forms, institutional structures, and legal identities distinct from parish churches, monastic churches, and episcopal residences. The cathedral is more important in the hierarchy than the church because it is from the cathedral that the bishop governs the area und ...
