Termite Barriers
Termite barriers are materials that have been specifically designed to prevent subterranean termites from gaining access to a structure. Physical termite barriers are free of pesticides and physically block termite foraging activity. Development of physical barriers to effectively exclude subterranean termites makes it possible to design and build structures with a far lower possibility of termite invasion and damage over the life of the building. Because of their small size ( long), impressive reproductive capability (a termite queen produces one egg every 3 seconds, or over 10 million eggs per year), and ability to eat through many construction materials, termites are the most destructive of all insects. Termite shields, an early physical barrier, are sheet metal fabrications used for decades in light frame construction. Termite shields are often applied underneath wood sill plates. They are designed to force termites to build their mud tubes outside of the structure, where the ... [...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 ...

Foraging
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary for survival and reproduction which have a l ...

Formosan Subterranean Termite
The Formosan termite (''Coptotermes formosanus'') is a species of termite local to southern China and introduced to Taiwan (formerly known as Formosa, where it gets its name), Japan, South Africa, Sri Lanka, Hawaii, and the continental United States. The Formosan termite is often nicknamed the super-termite because of its destructive habits due to the large size of its colonies and its ability to consume wood at a rapid rate. Populations of these termites have become large enough to appear on New Orleans' weather radars. A mature Formosan colony can consume as much as 13 ounces of wood a day (about 400 g) and can severely damage a structure in as little as three months. Formosan termites infest a wide variety of structures (including boats and high-rise condominiums) and can damage trees. In the United States, along with another species, '' Coptotermes gestroi'', introduced from Southeast Asia, they are responsible for tremendous damage to property resulting in large treatment ...

Termite Shield
A termite shield is a sheet metal fabrication used in light frame construction to reduce the movement of termites from the soil into wood framing members such as floor joists and Wall stud, studs. Although there are several types of non chemical termite Barricade, barriers now in use, termite shields are the original. Materials Termite shields can be made up of various materials. One type of termite shield is made from various sheet metals including galvanized steel, terne, copper, or aluminum. The metal is formed to fit between the top of the Foundation (engineering), foundation wall and the bottom of the wood sill plate. The edges of the termite shield are typically hemmed, extended slightly beyond the face of the wall, and turned down to form a drip edge which diverts water running down the face of the wall and reduce the movement of subterranean termites from the soil up into the wood framing members. Termite shields will not protect a building from termite activity, but h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
