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, [1] Hawaii, and the continental United States.

Contents

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. [2]

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 and repair costs.

History

[12] Formosan termites are rarely found north of 35°N. They have been reported in 11 states, including Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, and Texas. Their distribution is restricted to southern areas of the United States because their eggs don't hatch below about 20 °C (68 °F). More information can also be found at University of Florida Entomology.

Spread of Formosan infestation

Formosan termites, since their probable landing at the Port of New Orleans around the middle of the 20th century, have become a most serious concern to pest control regulators and researchers. In the 1970's, the United States Department of Agriculture began to track the spread of Formosan infestations. Maps of counties infested by Formosans were published by the USDA in 1975, 1990, and 2001. Universities across Texas, Louisiana, Mississippi, and Florida have published updates since then.

The annual expansion rate of Formosan infestation between 1990 and present varies from 5.3% in Mississippi to 8.1% in Texas.

Chouvenc & Helmick 2015 find that C. formosanus readily hybridizes with another invasive termite in Florida, C. gestroi . [13]

Economic impact

Historic structures in Hawaii have been threatened, such as Iolani Palace in Honolulu. [14] [15]

It has its greatest impact in North America. [16] [17] [18] C. formosanus is the most destructive, difficult to control, and economically important species of termite in the southern United States. [19]

The Florida Department of Agriculture and Consumer Services discusses the average cost of Formosan termite damage as "in the $10,000 range per home.......can be much higher...in some severe cases the home may have to be demolished and rebuilt." Florida Consumer Protection. [20]

Formosan termite barriers

Physical barriers to Formosan termites have been developed. Most of these barriers must be installed during construction, but a few can be installed after construction. The most important application of these post construction barriers is the stone particle barrier, used to protect exposed concrete perimeters.

The International Code Council (ICC) has issued an acceptance standard AC 380 Acceptance Criteria for Termite Physical Barrier Systemswhich requires five years of controlled field trials in multiple Formosan termite infested locations. [21] These acceptance criteria are rigorous and are drawn from the criteria used by state and federal pest control regulators for termite control methods.

Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus. They are distinguished by their moniliform antennae and the soft-bodied and often unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants, to which they are only distantly related. About 2,972 extant species are currently described, 2,105 of which are members of the family Termitidae.

<i>Reticulitermes flavipes</i> Species of insect found in North America

Reticulitermes flavipes, the eastern subterranean termite, is the most common termite found in North America. These termites are the most economically important wood destroying insects in the United States and are classified as pests. They feed on cellulose material such as the structural wood in buildings, wooden fixtures, paper, books, and cotton. A mature colony can range from 20,000 workers to as high as 5 million workers and the primary queen of the colony lays 5,000 to 10,000 eggs per year to add to this total.

The Sentricon Termite Colony Elimination System is a subterranean termite pest control product developed and manufactured by Corteva. It was introduced in 1995 as a termite baiting system and an alternative to liquid termicide soil barriers. It eliminates all members of the termite colony, including those of the Formosan subterranean termite colonies.

<span class="mw-page-title-main">Rhinotermitidae</span> Family of termites

Rhinotermitidae is a family of wood-soil interface feeding termites commonly known as the Subterranean termites. Many members of this family are known pests that can cause extensive damage to buildings or other wooden structures. Most species establish colonies in wood before migrating to the ground to create diffuse nests connecting to multiple pieces of wood, with some taxa such as Coptotermitinae creating mounds or centralized carton nests within wood. All members forage via shelter tubes through the soil to sources of food. In addition, Rhinotermitidae are known for having a higher level of social complexity as compared to other termites. Communication takes place through chemical activity, more specifically through traces of cuticular hydrocarbon (CHC), or semiochemicals, acting as pheromones to send signals to the king and queen of the nest. About 345 species are recognized, among these are severe pests such as Coptotermes formosanus, Coptotermes gestroi, and Reticulitermes flavipes.

<i>Coptotermes</i> Genus of termites

Coptotermes is a genus of termites in the family Rhinotermitidae. Many of the roughly 71 species are economically destructive pests. The genus is thought to have originated in Southeast Asia. Worker termites from this genus forage underground and move about in roofed tunnels that they build along the surface.

<i>Coptotermes acinaciformis</i> Species of termite

Coptotermes acinaciformis is a species of subterranean termite in the family Rhinotermitidae native to Australia. Termites are social insects and build a communal nest. In the case of C. acinaciformis, this is either in the root crown of a tree or underground. From this, a network of galleries extends through the nearby soil, enabling the workers to forage in the surrounding area without emerging on the surface of the ground. This termite can cause substantial damage to trees and the wooden parts of buildings.

The Indo-Malaysian drywood termite,, is a species of dry wood termite of the genus Cryptotermes. It is found in Philippines, Australia, Papua New Guinea, Hawaii, and introduced to Sri Lanka. It is the smallest termite species in Australia, with 2.5 – 3.7mm in soldiers.

It is a pest of many economically valuable trees such as Hevea brasiliensis and Camellia sinensis, and also an inhabitant of Anacardium occidentale, Cocos nucifera, Ficus fergusonii, Gliricidia sepium, Grevillea robusta, Madhuca longifolia, Tamarindus indica and Theobroma cacao.

<i>Odontotermes horni</i> Species of termite

Odontotermes horni, is a species of termite of the genus Odontotermes. It is native to India and Sri Lanka. It attacks many dead, decaying trees and fertilized soil. Though nests on ground, they do not construct a termitaria. It is a pest of tea, coconut and sugarcane.

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, impressive reproductive capability, and ability to eat through many construction materials, termites are the most destructive of all insects.
