Woodboring Beetles
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 usually 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.

Ambrosia Beetle
Ambrosia beetles are beetles of the weevil subfamilies Scolytinae and Platypodinae (Coleoptera, Curculionidae), which live in nutritional symbiosis with ambrosia fungi. The beetles excavate tunnels in dead or stressed trees into which they introduce fungal gardens, their sole source of nutrition. After landing on a suitable tree, an ambrosia beetle excavates a tunnel in which it releases its fungal symbiont. The fungus penetrates the plant's xylem tissue, extracts nutrients from it, and concentrates the nutrients on and near the surface of the beetle gallery. Ambrosia fungi are typically poor Wood-decay fungus, wood degraders, and instead utilize less demanding nutrients. Symbiotic fungi produce and detoxify ethanol, which is an attractant for ambrosia beetles and likely prevents growth of Antagonism (phytopathology), antagonistic pathogens and selects for other beneficial symbionts. The majority of ambrosia beetles colonize xylem (sapwood and/or heartwood) of recently dead trees, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building Defects
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, 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 separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Nebraska–Lincoln
The University of Nebraska–Lincoln (Nebraska, NU, or UNL) is a Public university, public Land-grant university, land-grant research university in Lincoln, Nebraska, United States.

Wood Ants
The ''Formica rufa'' group is a subgeneric group within the genus ''Formica'', first proposed by William Morton Wheeler. This group contains the mound-building species of ''Formica'' commonly termed "wood ants" or "thatch-mound ants", which build prominent nests consisting of a mound of grass, litter, or conifer needles. The species ''Formica rufa'' or the red wood ant is the type species of this subgroup. This particular group can inhabit open deciduous woodlands, dense pine forests, and even moorland. Workers vary in size, the largest reaching about long. They can produce formic acid in their abdomens and eject it in the air when threatened.Dr Timothy BatcheloMsu.edu - Southern red wood ant Formica rufa/ref> The only function of males is to mate in flight with queens. Species previously attributed to the ''Microgyna'' group were transferred to the '' F. rufa'' group by the Wheelers in 1986. Colonies The genetic relationships in ''F. rufa'' group colonies can be complex. Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termite
Termites are a group of detritivore, detritophagous Eusociality, eusocial cockroaches which consume a variety of Detritus, decaying plant material, generally in the form of wood, Plant litter, leaf litter, and Humus, soil humus. They are distinguished by their moniliform antennae and the soft-bodied, unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants but highly Apomorphy and synapomorphy, derived cockroaches. About 2,997 extant species are currently described, 2,125 of which are members of the family Termitidae. Termites comprise the infraorder Isoptera, or alternatively the Taxonomic rank#All ranks, epifamily Termitoidae, within the order Blattodea (the cockroaches). Termites were once classified in a separate Order (biology), order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood-eating cockroaches of t ...

Carpenter Ant
Carpenter ants (''Camponotus'' spp.) are a genus of large ants (workers ) indigenous to many parts of the world. True carpenter ants build nests inside wood, consisting of galleries chewed out with their mandibles or jaws, preferably in dead, damp wood. However, unlike termites, they do not consume wood, but instead discard a material that resembles sawdust outside their nest. Sometimes, carpenter ants hollow out sections of trees. They also commonly infest wooden buildings and structures, causing a widespread problem: they are a major cause of structural damage. Nevertheless, their ability to excavate wood helps in forest decomposition. The genus includes over 1,000 species. They also farm aphids. In their farming, the ants protect the aphids from predators (usually other insects) while they excrete a sugary fluid called honeydew, which the ants get by stroking the aphids with their antennae. Description Carpenter ants are generally large ants: workers are usually 4–7&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hylotrupes
''Hylotrupes'' is a monotypic genus of woodboring beetles in the family Cerambycidae, the longhorn beetles. The sole species, ''Hylotrupes bajulus'', is known by several common names, including house longhorn beetle, old house borer, and European house borer. In South Africa it also is known as the Italian beetle because of infested packing cases that had come from Italy. ''Hylotrupes'' is the only genus in the tribe Hylotrupini. Distribution This species, originating in Europe, and having been spread in timber and wood products, now has a practically cosmopolitan distribution, including Southern Africa, Asia, the Americas, Australia, and much of Europe and the Mediterranean. Description ''Hylotrupes bajulus'' can reach a body length of about , while mature larva can reach . These beetles are brown to black, appearing grey because of a fine grey furriness on most of the upper surface. On the pronotum two conspicuously hairless tubercles are characteristic of the species. On the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bostrichidae
The Bostrichidae are a family of beetles with more than 700 described species. They are commonly called auger beetles, false powderpost beetles, or horned powderpost beetles. Anatomy The head of most auger beetles cannot be seen from above, as it is downwardly directed and hidden by the thorax. Exceptions are the powderpost beetles (subfamily Lyctinae), and members of the subfamily Psoinae. ''Bostrychoplites cornutus'' has large, distinctive thoracic horns, and is found in parts of Africa and Arabia; it is often imported to Europe as larvae in African wooden bowls ("ethnic souvenirs") . Fossils The fossil record of the family extends to the Cretaceous, with the oldest records being from the Cenomanian aged Charentese and Burmese ambers, belonging to the extant genus '' Stephanopachys'' and the extant subfamilies Dinoderinae and Polycaoninae. Selected species This list is incomplete: * '' Amphicerus cornutus'' (Pallas, 1772) * '' Apate terebrans'' (Pallas, 1772) * '' ...

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 beetle, as well as the Cigarette beetle, cigarette, Drugstore beetle, drugstore and Common furniture beetle, furniture 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 P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powderpost Beetle
Powderpost beetles are a group of seventy species of woodboring beetles classified in the insect subfamily Lyctinae. These beetles, along with spider beetles, death watch beetles, common furniture beetles, skin beetles, and others, make up the superfamily Bostrichoidea. While most woodborers have a large prothorax, powderpost beetles do not, making their heads more visible. In addition to this, their antennae have two-jointed clubs. They are considered pests and attack deciduous trees, over time reducing the wood to a powdery dust. The damage caused by longhorn beetles (family Cerambycidae) is often confused with that of powderpost beetles, but the two groups are unrelated. The larvae of the Cerambycidae are white, straight and generally flat-headed, whereas those of the Bostrichidae are white and C-shaped. Name The term "powderpost" comes from the fact that the larvae of these beetles feed on wood and, given enough time, can reduce it to a mass of fine powder. Because of ...
