Coptotermes Gestroi
''Coptotermes gestroi'', the Asian subterranean termite is a small species of termite that lives underground. Both this species and the Formosan subterranean termite, (''Coptotermes formosanus'') are destructive pests native to Asia, but have spread to other parts of the world including the United States. In Asia, this species is known as the Philippine milk termite. The termite species ''Coptotermes havilandi'' was determined by Kirton and Brown in 2003 to be identical to ''Coptotermes gestroi'', so following the , the older name is now used. Distribution ''C. gestroi'' is endemic to Southeast Asia, but has spread to many other parts of the world over the course of the ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erich Wasmann
Erich Wasmann (29 May 1859 in Merano − 27 February 1931 in Valkenburg, Netherlands) was an Austrian (born in South Tyrol) entomologist, specializing in ants and termites, and Jesuit priest. He described the phenomenon known as Wasmannian mimicry and became a prominent Catholic popularizer of science, grounded in Christian beliefs, around 1900. Wasmann was a supporter of evolution, although he did not accept the productivity of natural selection, the evolution of humans from other animals, or universal common descent of all life. Rather, he believed that common ancestry was restricted to what he called "natural species" which were generally larger groups than species (which he called "systematic species"), genera, or even families. His natural species he identified with the "paleontological species" of Melchior Neumayr. Wasmann's reflections on evolution, while viewed with some concern by his Jesuit superiors, were popular among Catholics; he was invited to write an a ...

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 d ...

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 cellulos ...

Swarm Behaviour
Swarm behaviour, or swarming, is a collective animal behaviour, collective behaviour exhibited by entities, particularly animals, of similar size which aggregate together, perhaps milling about the same spot or perhaps moving ''en masse'' or animal migration, migrating in some direction. It is a highly interdisciplinary topic. As a term, ''swarming'' is applied particularly to insects, but can also be applied to any other entity or animal that exhibits swarm behaviour. The term ''flocking (behavior), flocking'' or ''murmuration'' can refer specifically to swarm behaviour in birds, ''herd behaviour, herding'' to refer to swarm behaviour in tetrapods, and shoaling and schooling, ''shoaling'' or ''schooling'' to refer to swarm behaviour in fish. Phytoplankton also gather in huge swarms called algal bloom, ''blooms'', although these organisms are algae and are not self-propelled the way animals are. By extension, the term "swarm" is applied also to inanimate entities which exhibit p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 c ...

Soldier Among Workers And Brood
A soldier is a person who is a member of an army. A soldier can be a conscripted or volunteer enlisted person, a non-commissioned officer, or an officer. Etymology The word ''soldier'' derives from the Middle English word , from Old French or , meaning mercenary, from , meaning shilling's worth or wage, from or , shilling. The word is also related to the Medieval Latin , meaning soldier (literally, "one having pay"). These words ultimately derive from the Late Latin word , referring to an Ancient Roman coin used in the Byzantine Empire. Occupational designations In most armies use of the word "soldier" has taken on a more general meaning due to the increasing specialization of military occupations that require different areas of knowledge and skill-sets. As a result, "soldiers" are referred to by names or ranks which reflect an individual's military occupation specialty arm, service, or branch of military employment, their type of unit, or operational employment or technica ...

Coptotermes Gestroi Workers And Brood
''Coptotermes'' is a genus of termites in the family Rhinotermitidae. Many of the roughlty 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. In Australia, ''Coptotermes'' colonies sometimes host a parasitic genus of termites, '' Ahamitermes''. The host and the parasite dwell in separate parts of the mound nest and are mutually antagonistic. The ''Ahamitermes'' species live in the innermost parts of the nest and feed on the "carton" material with which the galleries are lined, which consists of soil particles, chewed wood, and cellulose, bound together with saliva and faeces. They are thus dependent on their hosts for both their food and their home and are not found in any other situations. Species This is an incomplete list of species: *'' Coptotermes acinaciformis'' *'' Coptotermes brunneus'' *'' Coptoter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fontanelle
A fontanelle (or fontanel) (colloquially, soft spot) is an anatomical feature of the infant human skull comprising soft membranous gaps ( sutures) between the cranial bones that make up the calvaria of a fetus or an infant. Fontanelles allow for stretching and deformation of the neurocranium both during birth and later as the brain expands faster than the surrounding bone can grow. Premature complete ossification of the sutures is called craniosynostosis. After infancy, the anterior fontanelle is known as the bregma. Structure An infant's skull consists of five main bones: two frontal bones, two parietal bones, and one occipital bone. These are joined by fibrous sutures, which allow movement that facilitates childbirth and brain growth. * Posterior fontanelle is triangle-shaped. It lies at the junction between the sagittal suture and lambdoid suture. At birth, the skull features a small posterior fontanelle with an open area covered by a tough membrane, where the two ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for Sensory system, sensing in arthropods. Antennae are connected to the first one or two Segmentation (biology), segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing tactition, touch, air motion, heat, vibration (sound), and especially insect olfaction, smell or gustation, taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate (biology), substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
