Reticulitermes Virginicus
''Reticulitermes virginicus'' is a species of subterranean termite native to North America, found often in the southern United States.Su, Nan-Yao.Native Subterranean Termites: ''Reticulitermes flavipes'' (Kollar), ''Reticulitermes virginicus'' (Banks), ''Reticulitermes hageni'' Banks (Insecta: Isoptera: Rhinotermitidae)" IFAS Extension, University of Florida. It was described in 1907. Like all other termite species, ''R. virginicus'' is a eusocial species, characterized by individuals in a colony with overlapped generations cooperating in brood care and having reproductive division of labor. The adults that grow wings and fly from the nest to find a mate and start a new colony are called alates, or winged reproductives. In this species they are dark brown. Alates leave the nest between early February and late May. They prefer warm and sunny afternoons after rain. Like in all other termite species, all four of their wings are equal length. ''R. virginicus'' alates have wings abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate 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 the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Southern United States
The Southern United States (sometimes Dixie, also referred to as the Southern States, the American South, the Southland, or simply the South) is a geographic and cultural region of the United States of America. It is between the Atlantic Ocean and the Western United States, with the Midwestern and Northeastern United States to its north and the Gulf of Mexico and Mexico to its south. Historically, the South was defined as all states south of the 18th century Mason–Dixon line, the Ohio River, and 36°30′ parallel.The South . ''Britannica.com''. Retrieved June 5, 2021.

Eusociality
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the ...

Division Of Labour
The division of labour is the separation of the tasks in any economic system or organisation so that participants may specialise (specialisation). Individuals, organizations, and nations are endowed with, or acquire specialised capabilities, and either form combinations or trade to take advantage of the capabilities of others in addition to their own. Specialised capabilities may include equipment or natural resources as well as skills, and training and combinations of such assets acting together are often important. For example, an individual may specialise by acquiring tools and the skills to use them effectively just as an organization may specialise by acquiring specialised equipment and hiring or training skilled operators. The division of labour is the motive for trade and the source of economic interdependence. Historically, an increasing division of labour is associated with the growth of total output and trade, the rise of capitalism, and the increasing complexity of ...

Nuptial Flight
Nuptial flight is an important phase in the reproduction of most ant, termite, and some bee species. It is also observed in some fly species, such as ''Rhamphomyia longicauda''. During the flight, virgin queens mate with males and then land to start a new colony, or, in the case of honey bees, continue the succession of an existing hived colony. The winged version of ants and termites are known as alates. Before the flight A mature ant colony seasonally produces winged virgin queens and males, called alates. Unfertilized eggs develop into males. Fertilized eggs usually develop into wingless, sterile workers, but may develop into virgin queens if the larvae receive special attention. Within a few days after they have emerged (eclosed) from the pupa case, males are "quickly converted into single-purpose sexual missiles." Young queens and males stay in their parent colony until conditions are right for the nuptial flight. The flight requires clear weather since rain is disrup ...

Alate
Alate (Latin ''ālātus'', from ''āla'' (“wing”)) is an adjective and noun used in entomology and botany to refer to something that has wings or winglike structures. In entomology In entomology, "alate" usually refers to the winged form of a social insect, especially ants or termites, though can also be applied to aphids and some thrips. An alate is a winged reproductive caste from a social insect colony in its winged form. Alate females are typically those destined to become gynes (queens), whereas alate males are occasionally referred to as "drones" (or "kings", in the case of termites). Their common behavioural function is starting a new colony, to expand their mother colonies etc. Colonies of termites and ants produce alates. It is a flight-based form of reproductive technique. In a termite colony, alates (winged males and winged females) disperse in a specific period or a month. Male and female pair to each other during flight, shed their wings, and start a new colo ...

Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symbiosis
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Cellulose
Cellulose is an organic compound with the formula , a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton. Some animals, particularly ruminants and termites, can digest cellulose with the help of ...

Eastern Subterranean Termite
''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. Distribution The eastern subterranean termite (''R. flavipes'') is the most widely distributed '' Reticulitermes'' species. It occurs throughout the eastern United States, including Texas, and can be found as far north as southern Ontario. In 2006, ''R. flavipes'' was also recorded in Oregon, on the West coast of the United States. ''Reticulitermes santonensis'' in France is now understood to be a synonym of ''R. flavipes''.

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 ...
