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, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common 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 fe ...

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.

Wharf Borer
The wharf borer, ''Nacerdes melanura'', belongs to the insect order Coleoptera, the beetles. They belong to the family Oedemeridae, which are commonly known as false blister beetles. Wharf borers are present in all the states of the USA except for Florida. It takes about a year to develop from an egg to an adult. The insect is called the 'wharf borer' because the larval stage of this insect is often found on pilings and timbers of wharves, especially along coastal areas. The adult beetles can be identified via a black band across the end of both elytra, or wing covers. In addition, wharf borers can be distinguished from other members of the family Oedemeridae via the presence of a single spur on the tibia of the forelegs, and the distance between both eyes (twice the length of one eye). Eggs are oviposited on rotten wood where larvae hatch and burrow to feed on rotten wood. Adults do not feed and depend on stored energy reserves accumulated during the larval stage. They are con ...

Bookworm (insect)
Bookworm is a general name for any insect that is said to bore through books. The damage to books that is commonly attributed to "bookworms" is often caused by the larvae of various types of insects including beetles, moths and cockroaches, which may bore or chew through books seeking food. The damage is not caused by any species of worm. Some such larvae exhibit a superficial resemblance to worms and are the likely inspiration for the term, though they are not true worms. In other cases, termites, carpenter ants, and woodboring beetles will first infest wooden bookshelves and later feed on books placed upon the shelves, attracted by the wood-pulp paper used in most commercial book production. True book-borers are uncommon. The primary food sources for many "bookworms" are the leather or cloth bindings of a book, the glue used in the binding process, or molds and fungi that grow on or inside books. When the pages themselves are attacked, a gradual encroachment across the surfac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of .

Ptinidae
Ptinidae is a family of beetles in the superfamily Bostrichoidea. There are at least 220 genera and 2,200 described species in Ptinidae worldwide. The family includes spider beetles and deathwatch beetles. The Ptinidae family species are hard to identify because they are so small, and they have a compact body structure. They also have similar morphologies within the genera and species of the family. There are three main groups in the superfamily Bostrichoidea: Bostrichidae, Anobiidae, and Ptinidae. These have undergone frequent changes in hierarchical classification since their inception. They have been treated as a single family, three independent families, the two families Bostrichidae and Anobiidae, or the two families Bostrichidae and Ptinidae. More recent literature treats these as the two families Bostrichidae and Ptinidae, with Anobiidae a subfamily of Ptinidae ( Anobiinae). Spider beetles are so named because they look like spiders. Some species have long legs, anten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Building Defects
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
