Yellow Crazy Ant
The yellow crazy ant (''Anoplolepis gracilipes''), also known as the long-legged ant or Maldive ant, is a species of ant, thought to be native to West Africa or Asia. They have been accidentally introduced to numerous places in the world's tropics. The yellow crazy ant has colloquially been given the modifier "crazy" on account of the ant's erratic movements when disturbed. Its long legs and antennae make it one of the largest invasive ant species in the world.''Anoplolepis gracilipes''. Global Invasive Species Database. ISSG.

Longhorn Crazy Ant
The longhorn crazy ant (''Paratrechina longicornis''), also known as "black crazy ant", is a species of small, dark-coloured insect in the family Formicidae. These ants are commonly called "crazy ants" because instead of following straight lines, they dash around erratically. They have a broad distribution, including much of the tropics and subtropics, and are also found in buildings in more temperate regions, making them one of the most widespread ant species in the world. This species, as well as all others in the ant subfamily Formicinae, cannot sting. However, this species can fire/shoot a formic acid spray from its abdomen when under attack by other insects or attacking other insects. When the longhorn crazy ant (''Paratrechina longicornis'') bends its abdomen while aiming at an enemy insect, it is most likely shooting its hard-to-see acid. This acid is normally not used on humans and normally does not affect humans. The ''black crazy ant'' can not harm humans in any way. Th ...

Ant Supercolony
An ant supercolony is an exceptionally large ant colony, consisting of a high number of spatially separated but socially connected nests of a single ant species (meaning that the colony is polydomous), spread over a large area without territorial borders. Supercolonies are typically polygynous, containing many egg-laying females (queens or gynes).''Supercolonies.''

Southeast Asia
Southeast Asia, also spelled South East Asia and South-East Asia, and also known as Southeastern Asia, South-eastern Asia or SEA, is the geographical United Nations geoscheme for Asia#South-eastern Asia, south-eastern region of Asia, consisting of the regions that are situated south of mainland China, east of the Indian subcontinent, and north-west of mainland Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia (continent), Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of atolls of Maldives, 26 atolls of Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is completely in the Northern Hemisphere. East Timor and the southern portion of Indonesia are the only parts that are south of the Equator. Th ...

Quarantine
A quarantine is a restriction on the movement of people, animals and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. Quarantine considerations are often one aspect of border control. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive ...

Pheidole
''Pheidole'' is a genus of ants that belongs to the ant subfamily Myrmicinae. The genus is widespread and ecologically dominant. It probably includes more than 1000 species. The genus first evolved in the Americas, eventually spreading across the globe. Colony structure Most species of ''Pheidole'' are dimorphic, which means that colonies contain two castes of workers, the "minor" workers, and the "major" workers, or "soldiers". The latter generally have much larger heads and mandibles in comparison to their usually fairly modest body size. In addition, as in other ant species, a colony may contain one or several queens, and also in mature colonies, alates - virgin winged females and males. Pheidole_xerophila-major_minors.jpg, major and minor workers of ''P. xerophila'' Major workers The distinctive major workers have earned the genus ''Pheidole'' the nickname of "big-headed ants".

Petiole (insect Anatomy)
In entomology, petiole is the technical term for the narrow waist of some hymenopteran insects, especially ants, bees, and wasps in the suborder Apocrita. The petiole can consist of either one or two segments, a characteristic that separates major subfamilies of ants. Structure The term 'petiole' is most commonly used to refer to the constricted first (and sometimes second) metasomal (posterior) segment of members of the hymenopteran suborder Apocrita (ants, bees, and wasps). It is sometimes also used to refer to other insects with similar body shapes, where the metasomal base is constricted. The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders. The plump portion of the abdomen posterior to the petiole (and postpetiole in the Myrmicinae) is called the gaster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acidopore
The acidopore is a component of ant anatomy; a round orifice located on the abdomen encircled by hairs which typifies the subfamily Formicinae. The conical structure connects to the posterior end of an ant's gaster where formic acid and other hydrocarbons are formed, collectively comprising the venom. Ants are able to disinfect fungus-infected brood by taking up acidopore venom into their mouth by self-grooming and applying it by brood grooming. This structure is unique to, but not present in all members of the ant subfamily Formicinae. It is termed an acidopore because it is the pore, or hole, from which formic acid is sprayed. See also *Ant venom Ant venom is any of, or a mixture of, irritants and toxins inflicted by ants. Most ants spray or inject a venom, the main constituent of which is formic acid only in the case of subfamily Formicinae. Ant stings Of all extant ant species, about 7 ...
