THE POOR PEOPLE

We see paintings of poor people, then we admire the artist who painted them.

We read articles and stories about poor people, then we are inspired with the writer who wrote them.

We watch movies about poor people, then we congratulate the film-maker who made them.

We were surprised about the survey on poor people,
then we just make presentations about them.

How much do we gain from these? And do we really give to the poor people after doing such things?

They are real people …not just object s to be manipulated..

Ant Anatomy:
--------------------------------------------------------------------------------
The anatomy of ants is very interesing. Use this diagram , that shows the main body parts of ants, and the information below to learn about about the anatomy of ants.

The first thing you will notice in this diagram of an ant's anatomy is the three main divisions. The head, the trunk, and the metasoma. Ant bodies, like other insects have an exoskeleton . Their skeleton is on the outside - not covered by skin, muscles, and tissue like humans.
The head of an ant has several imporatant parts. First the eyes. Ant eyes are a lot like flies. They have many small eyes connected together. This enables ants to see movement very well.
Also Attached to the head of the ant are two feelers. The feelers are special organs of smell that help ants communicate. If you have every seen an ant find a food source, it is not long before the ant communicates to his friends and their are many ants there. Ants release pheromones (chemicals that have different smells) to communicate with each other. The feelers pick up these smells as signals.
The head also has two strong pinchers which are used to carry food, to dig, and to defend. Just inside the mouth is a small pocket where ants can store food. They can give this food to other ants in need.
The trunk of the ant is where all 6 legs are attached. At the end of each leg is a sharp claw that helps ants climb and hang onto things.
The metasoma of the ant is a poison sack. Ants are closely related to wasps and other stinging insects. Many types of ants have stingers and can inflict a very painful sting. This is a useful way to defend against the many predators ants have.
Inside Ants do not have lungs. Oxygen enters through tiny holes all over the body and Carbon Dioxide leaves through the same holes. There are no blood vessels. The heart is a long tube that pumps colorless blood from the head back to the rear and then back up to the head again. The blood kind of coats the insides of the ants and is then sucked into the tube and pumped up to the head again. The nervous system of ants consists of a long nerve cord that also runs from head to rear with branches leading to the parts of the body, kind of like a human spinal cord.

Communication

Ants communicate with each other through chemicals called pheromones. These chemical signals are more developed in ant species than in other hymenopteran groups. Like other insects, ants smell with their long and thin antennae that are fairly mobile. The antennae have a distinct elbow joint after an elongated first segment; and since they come in pairs—rather like binocular vision or stereophonic sound equipment—they provide information about direction as well as intensity. Since ants spend their life in contact with the ground, the soil surface makes a good place to leave a pheromone trail that can be followed by other ants. In those species which forage in groups, when a forager finds food they mark a trail on the way back to the colony, and this is followed by other ants that reinforce the trail when they head back to the colony. When the food is exhausted, no new trails are marked by returning ants and the scent slowly dissipates. This behavior helps ants adapt to changes in their environment. When an established path to a food source is blocked by a new obstacle, the foragers leave the path to explore new routes. If successful, the returning ant leaves a new trail marking the shortest route. Successful trails are followed by more ants, and each reinforces the trail with more pheromone (ants will follow the heaviest marked trails). Home is often located by remembered landmarks in the area and by the position of the sun; ants' compound eyes have specialized cells that detect polarized light, used to determine direction.[19][20]
Ants use pheromones for other purposes as well. A crushed ant will emit an alarm pheromone which in high concentration sends nearby ants into an attack frenzy; and in lower concentration, merely attracts them. To confuse enemies, several ant species use "propaganda pheromones", which cause their enemies to fight amongst themselves.[21]
Pheromones are produced by a wide range of glandular structures including cloacal glands, Dufour's glands, the hindgut, poison glands, pygidial glands, rectal glands, sternal gland and tibial glands on the back legs.[13]
Pheromones are also exchanged mixed with food and passed in the trophallaxis, giving the ants information about one another's health and nutrition. Ants can detect what task group (e.g. foraging or nest maintenance) other ants belong to. When the queen stops producing a specific pheromone the workers raise new queens.
Some ants also produce sounds by stridulation using the gaster segments and also using their mandibles. They may serve to communicate among colony members as well as in interactions with other species.[22][23][24]
Defense

Ants attack others and defend themselves by biting and in many species, stinging, often injecting chemicals like formic acid. Bullet ants (the genus Paraponera), located in Central and South America, are considered to have the most painful sting among insects, although these are usually non-fatal. They are given the highest rating on the Schmidt Sting Pain Index. Jack jumper ants, Myrmecia pilosula, located in Australia have stings that may kill the small proportion of susceptible people in the population, and cause hospitalizations each year.[25] A vaccine based on use of the venom extract to develop immunity has been developed.[26]
Fire ants, Solenopsis spp., are unique in having a poison sac containing piperidine alkaloids.[27]
Some ants of the genus Odontomachus are equipped with mandibles called trap-jaws. This snap-jaw mechanism, or catapult mechanism, is possible because energy is stored in the large closing muscles. The blow is incredibly fast, about 0.5 ms in the genus Mystrium. Before the strike, the mandibles open wide and are locked in the open position by the labrum, which functions as a latch. The attack is triggered by stimulation of sensory hairs at the side of the mandibles. The mandibles are also able to function as a tool for more finely adjusted tasks. Two similar groups are Odontomachus and Dacetini - examples of convergent evolution.
Apart from defense against larger threats, ants also need to defend their colonies against disease organisms. Some ant workers' role is to maintain the hygiene of the colony and their activities include undertaking or necrophory, the transport of dead nest-mates.[28] Oleic acid is identified as one compound released by dead ants that triggers undertaking behaviour in Atta mexicana.[29]
The nests are also protected from physical threats such as flooding by elaborate structures at the entrance or special chambers for escaping from flooding. Some arboreal species that live in plant hollows also have behavioural responses to flooding, where the workers drink the water and excrete it outside the nest.[30]
Learning
While many types of animals can learn behaviors by imitating other animals, ants may be the only group of animals besides primates and some other mammals in which interactive teaching behavior has been observed. Knowledgeable forager ants of the species Temnothorax albipennis directly lead naïve nest-mates to newly discovered food sources by the excruciatingly slow (and time-costly) process of tandem running. The follower thereby obtains knowledge that it would not have, had it not been tutored, and this is at the expense of its nest-mate teacher. Both leader and follower are acutely sensitive to the progress of their partner. For example, the leader slows down when the follower lags too far behind, and speeds up when the follower gets too close, while the follower does the opposite.[31]
Controlled experiments with colonies of Cerapachys biroi suggest that these ants can specialize based on their previous experience. An entire generation of identical workers was divided into two groups based on how the researchers controlled the outcome of food foraging. One group was continually rewarded with prey, while it was made certain that the other failed. As a result, members of the successful group intensified their foraging attempts while the unsuccessful group ventured out less and less. One month later, 'workers that previously found prey kept on exploring for food, whereas those who always failed specialized in brood care'[32]
Nest construction
Main article: Ant colony

While some ants form complex nests and galleries, other species are nomadic and do not build permanent structures. Various species may form subterranean nests or build them on trees. Nests can be found in the ground with craters or mounds around the entrance, under stones or logs, in logs, hollow stems, even acorns. The materials used for construction include soil and plant matter,[33] and they are highly selective of the nest site; Temnothorax albipennis will avoid sites with dead ants as these may be indicators of pests or disease. They are also quick to abandon established nest sites at the first sign of these threats.[34]
Some of the more advanced ants are the army ants and driver ants, from South America and Africa respectively. Unlike most species which have permanent nests, army and driver ants do not form permanent nests, but instead alternate between nomadic stages and stages where the workers form a temporary nest (bivouac) out of their own bodies. Colonies reproduce either through nuptial flights as described above, or by fission, where a group of workers simply dig a new hole and raise new queens. Colony members are distinguished by smell, and other intruders are usually attacked.
Weaver ants (Oecophylla) build nests in trees by attaching leaves together, first pulling them together with bridges of workers and then sewing them together by pressing silk-producing larvae against them in alternation.
Food cultivation
Main article: Ant-fungus mutualism
Leafcutter ants (Atta and Acromyrmex) feed exclusively on a special fungus that lives only within their colonies. They continually collect leaves which they cut into tiny pieces for the fungus to grow on. There are different sized castes specially suited to finer and finer tasks of cutting and chewing the leaves and tending to the garden. Leaf cutter ants are sensitive enough to adapt to the fungi's reaction to different plant material, apparently detecting chemical signals from the fungus. If a particular type of leaf is toxic to the fungus the colony will no longer collect it. The ants grow the fungus because it produces special structures called gongylidia which are fed on by the ants. They create antibiotics on their exterior surfaces with the aid of symbiotic bacteria, and subsist entirely on this farming of the fungus.[35]
Navigation
Desert ants Cataglyphis fortis make use of visual landmarks in combination with other cues to navigate.[36]
In the absence of visual landmarks, Sahara desert ants have been shown to navigate by keeping track of direction as well as distance travelled, like an internal pedometer that keeps tracks of how many steps they take, and use this information to find the shortest routes back to their nests.[37]
Locomotion

Ants rafting in a pool
Worker ants generally do not grow wings and reproductive females remove theirs after their mating flights in order to begin their colonies. Therefore, unlike their wasp ancestors, most ants travel by walking.
The more cooperative species of ants sometimes form chains to bridge gaps, whether that be over water, underground, or through spaces in arboreal paths. Some species also form floating rafts that help them survive floods. They may also have a role in colonization of islands.[38]

Harpegnathos saltator, a jumping ant
Some ants are even capable of leaping. A particularly notable species is Jerdon's jumping ant, Harpegnathos saltator. Jumps are made by the synchronized action of the mid and hind pair of legs.[39]
Polyrhachis sokolova, a species of ant found in Australian mangrove swamps, can swim and lives in nests that are submerged underwater. They make use of trapped pockets of air in the submerged nests.[40]
There are several species of gliding ant including Cephalotes atratus. In fact this may be a common trait among most arboreal ants. Ants with this ability are able to direct the direction of their descent while falling.[41]
Ant cooperation and competition

Meat eater ants feeding on honey - social ants cooperate and collectively gather food.
Not all ants have the same kind of societies. The Australian bulldog ants are among the biggest and most primitive of ants. The individual hunts alone, using its large eyes instead of its chemical senses to find prey. Like all ants they are social, but their social behavior is poorly developed compared to more advanced species.
Some species of ants are known for attacking and taking over the colonies of other ant species. Others are less expansionist but nonetheless just as aggressive; they attack colonies to steal eggs or larvae, which they either eat or raise as workers/slaves. Some ants, such as the Amazon ants, are incapable of feeding themselves, and must rely on captured worker ants to care for them. In some cases ant colonies may have other species of ants or termites within the same nest.[42]
Some ant species enter the colonies of others and establish themselves as social parasites. Some like Strumigenys xenos are parasitic to the extent that they do not have workers but instead rely on their Strumigenys perplexa hosts.[43][44]
The pavement ant is famous for its urge to increase its territory. In early spring, colonies attempt to conquer new areas and often attack the nearest enemy colony. These result in huge sidewalk battles, sometimes leaving thousands of ants dead. Because of their aggressive nature, they often invade and colonize seemingly impenetrable areas.
Ants identify kin and nestmates through their scents, a hydrocarbon-laced secretion that coats their exoskeletons. If an ant is separated from its original colony, it will eventually lose the colony scent. Any ant that enters a colony with a different scent than that of the colony will be attacked.[45] (See also Kin selection)

There is a great diversity among ants and their behaviors. They range in size from 2 to about 25 mm (about 0.08 to 1 inch). Their color may vary; most are red or black, but other colors can also be seen, including some tropical groups with a metallic luster. (See also ant genera). Numerous species of ant continue to be added in present times and taxonomic studies continue to resolve the classification and systematics of ants. Online databases of ant species include AntBase and the Hymenoptera Name Server.[46]
Ants have been used as indicator species in biodiversity studies.[47][48]
Relationships with other species
Ants associate with a wide range of species in many ways. They form mutualisms with other insects, plants, and fungi. They parasitize each other. They are preyed upon by many animals and even certain fungi. Because their nests are such hospitable places, many species of arthropods sneak in and integrate themselves in various ways to the ant's daily lives. These inquilines sometimes bear a close resemblance to ants. The adaptive significance of resemblance to ants, or myrmecomorphy, is not clear. The exact nature of mimicry varies with some cases involving Batesian mimicry, where the mimic reduces the risk of predation. Other forms include Wasmannian mimicry, that are associated with inquilinism.[49][50]
Aphids secrete a sweet liquid called honeydew which they exude in the process of feeding from plants. The sugars can provide a high-energy food source, which many ant species collect. In some cases the aphids secrete the honeydew specifically in response to the ants tapping them with their antennas. The ants in turn keep predators away and will move the aphids around to better feeding locations. Upon migrating to a new area, many colonies will take new aphids with them, to ensure that they have a supply of honeydew in the new area. Ants also tend mealybugs to harvest their honeydew. Mealybugs can become a serious pest of pineapple if ants are present to protect mealybugs from natural enemies.[51][52]

An ant collects honeydew from an aphid.
Myrmecophilous (ant-loving) caterpillars of the family Lycaenidae (e.g., blues, coppers, or hairstreaks) are herded by the ants, led to feeding areas in the daytime, and brought inside the ants' nest at night. The caterpillars have a gland which secretes honeydew when the ants massage them. Some caterpillars are known to produce vibrations and sounds that are sensed by the ants.[53] Some caterpillars have evolved from being ant-loving to ant-eating and these myrmecophagous caterpillars secrete a pheromone which makes the ants think that the caterpillar is one of their own larvae. The caterpillar is then taken into the ants' nest where it feeds on the ant larvae.
Fungus-growing ants that make up the tribe attini, including leafcutter ants, actively cultivate certain species of fungus in the Leucoagaricus or Leucocoprinus genera of the Agaricaceae family. In this ant-fungus mutualism, both species depend on each other for survival. The ant Allomerus decemarticulatus has evolved a tripartite association with their host plant Hirtella physophora (Chrysobalanaceae), and a sticky fungus which is used to trap their insect prey.[54]
Lemon ants make devil's gardens by selectively killing surrounding plants and leaving a pure patch of lemon ant trees Duroia hirsuta.[55] Many trees have extrafloral nectaries that provide food for ants and the ants in turn protect the plant from herbivorous insects.[56] Some species like the bullhorn acacia, Acacia cornigera, in Central America have hollow thorns that serve to house colonies of stinging ants, Pseudomyrmex ferruginea, that defend the tree against insects, browsing mammals, and epiphytic vines. In return, the ants obtain food from protein-lipid Beltian bodies. Another example of this type of ectosymbiosis comes from the Macaranga tree which have stems adapted to house colonies of Crematogaster ants. Many tropical tree species have seeds that are dispersed by ants.[57] Seed dispersal by ants or myrmecochory is widespread particularly in Africa and Australia.[58]
Flies in the Old World genus Bengalia (Calliphoridae) are kleptoparasites and predators on ants and often snatch prey or brood from the adult ants.[59] Wingless and legless females of the Malaysian phorid fly Vestigipoda myrmolarvoidea live in the nests of ants of the genus Aenictus and are cared for by the ants.[59]
Many species of birds show a peculiar behaviour called anting that is as yet not fully understood. Here birds may rest on ant nests or pick and drop ants onto their wings and feathers, presumably to rid themselves of ectoparasites.
A fungus, Cordyceps, infects ants, causing them to climb up plants and sink their mandibles into the plant tissue. The fungus kills and engulfs the ant and produces its fruiting body. It appears that the fungus alters the behavior of the ant and uses the ant to help disperse its spores.[60]
Some South American frogs in the genus Dendrobates feed primarily on ants and the toxins on their skin may be derived from the ants.[61]
Brown bears (Ursus arctos) have been found to feed on ants, with as much as 12%, 16%, and 4% of their fecal volume in spring, summer, and autumn, respectively being made up of ants.[62]
Many species of mammals such as anteaters, pangolins and several marsupial species in Australia have special adaptations for living on a primary diet of ants. These adaptations include long sticky tongues to pick the ants and strong claws to break into the ant nests. Some South American birds such as the antpittas are also ant predators.
Humans and ants

Ants are useful for clearing out insect pests and aerating the soil. The use of weaver ants in citrus cultivation in southern China is one of the oldest known uses of biological control.[33] On the other hand, they can become annoyances when they invade homes, yards, gardens and fields. Carpenter ants damage wood by hollowing it out for nesting.
In some parts of the world large ants, especially army ants, are said to be used as sutures by pressing the wound together and applying ants along it. The ant in defensive attitude seizes the edges in its mandibles and locks in place. The body is then cut off and the head and mandibles can remain in place, closing the wound.[63]
Some ants of the family Ponerinae have toxic venom and are of medical importance. The species include Paraponera clavata (Tocandira) and Dinoponera spp. (false Tocandiras) of South America[64] and the Myrmecia ants of Australia.[65]
The Masai of Africa had an abiding respect for the Siafu ants, voracious predators that consume a large amount of insects and are welcomed for the benefit they bring to farmers, as they will eliminate all pests from a crop and quickly move on.
In South Africa, ants are used to help harvest rooibos, Aspalathus linearis, the small seeds of which are used to make a herbal tea.[66]
Ants as food
Main article: Entomophagy
Ants and their larvae are eaten in different parts of the world. The eggs of two species of ants are the basis for the dish in Mexico known as "escamoles". They are considered a form of insect caviar and can sell as high as $40 USD per pound because they are seasonal and hard to find. In the Colombian department of Santander, hormigas culonas (lit.: "fatass ants") Atta laevigata are toasted alive and eaten.[67] This tradition has come down from the native Guanes. In parts of Thailand, ants are prepared and eaten in various ways. Khorat ant eggs and diced flying ants are eaten as an appetizer. Weaver ant eggs and larvae as well as the ants themselves may be used in a Thai salad, yum (ยำ), in a dish called yum khai mod daeng (ยำไข่มดแดง) or red ant egg salad, a dish that comes from the Issan or north-eastern region of Thailand. Weaver ant queens may also be eaten live, at the time of nest initiation.
In parts of India, and throughout Burma and Siam, a paste of the green weaver ant, Oecophylla smaragdina, is served as a condiment with curry.[68] Saville Kent, in the Naturalist in Australia wrote "Beauty, in the case of the green ant, is more than skin-deep. Their attractive, almost sweetmeat-like translucency possibly invited the first essays at their consumption by the human species." Mashed up in water, after the manner of lemon squash, "these ants form a pleasant acid drink which is held in high favor by the natives of North Queensland, and is even appreciated by many European palates."[69]
John Muir, in his First Summer in the Sierra notes that the Digger Indians of California ate the tickly acid gasters of the large jet-black carpenter ants. The Mexican Indians eat the replete workers, or living honey-pots, of the honey ant (Myrmecocystus).[69]
In Brazil queen ants are considered a delicacy for part of the population. In the month of November they appear in great quantities, within a span of a few hours. People collect them, taking only their large abdomen and discarding the rest and they are eaten. If large numbers are collected the abdomens are then fried, sometimes mixed with manioc flour.[70]
Ants as pests
Modern society considers the ant a pest,[71] and because of the adaptive nature of ant colonies, eliminating them is nearly impossible. Pest control is a matter of controlling local populations, instead of eliminating an entire colony, most attempts at control are temporary solutions.
Typical ants that are classified as pests include pavement ants (otherwise known as the sugar ant), Pharaoh ants, carpenter ants, Argentine ants, and the red imported fire ant. Control of species populations are usually done with bait insecticides, which are either in the form of small granules, or as a sticky liquid that is gathered by the ants as food and then brought back to the nest where the poison is inadvertently spread to other members of the brood — a system that can severely reduce the numbers in a colony if used properly. Boric acid and borax are often used as insecticides that are relatively safe for humans. With the recent insurgence of the red imported fire ant, a tactic called broadcast baiting has been employed, by which the substance (usually a granule bait designed specifically for fire ants) is spread across a large area, such as a lawn, in order to control populations. Nests may be destroyed by tracing the ants' trails back to the nest, then pouring boiling water into it to kill the queen. This works in about 60% of the mounds and needs about 14 litres (3 gallons) per mound.[72]
Ants that tend other insects can indirectly cause pest infestations. Many homopteran insects that are considered as horticultural pests are controlled by the use of grease rings on the trunks of the trees. These rings cut off the routes for ants and make the pest species vulnerable to parasites and predators.
Studying ants
Myrmecologists study ants both in the laboratory and in their natural conditions using a number of tools and techniques. Ants are model organisms for the study of sociobiology and the testing of hypotheses such as those based on the theories of kin selection or evolutionarily stable strategies. Ant colonies can be reared or temporarily maintained in specially constructed glass frames for study purposes.[73] For certain kinds of studies it is necessary to identify specific individual ants through the study period and this is achieved by use of colour marking techniques.[74] The use of endoscopes to observe ants inside their nest tunnels is another technique that has been used in the field.
Ant inspired technology
The successful techniques used by ant colonies has been widely studied especially in computer science and robotics to produce distributed and fault-tolerant systems for solving problems. This area of biomimetics has led to studies of ant locomotion, search engines which make use of foraging trails and fault tolerant storage and networking algorithms.[75] (See also Langton's ant and ant colony optimization.)
Ants in culture

Aesop's ants. Picture by Milo Winter, 1888-1956.
Ants have often been used in fables and children's stories to represent industriousness and cooperative effort, as well as aggressiveness and vindictiveness. They are also mentioned in religious texts.[76][77] In the Book of Proverbs in the Bible ants are held up as a good example for humans for their hard work and cooperation. Aesop did the same in his fable "The Grasshopper and the Ants". In parts of Africa, ants are considered to be the messengers of the gods. Ant bites are often said to have curative properties. The sting of some species of Pseudomyrmex is claimed to give fever relief.[78] Some Native American religions, such as Hopi mythology, recognize ants as the very first animals. Others use ant bites in initiation ceremonies as a test of endurance.[79][80]
The Japanese word for ant, ari, is represented by an ideograph formed of the character for insect combined with the character signifying moral rectitude, propriety (giri). So the Japanese character could possibly be read as The Propriety-Insect. Its actual etymology is likely to be different however.[81]
Ant society has always fascinated humans and has been written about both humorously and seriously by writers. Mark Twain wrote about ants in his A Tramp Abroad. Some modern authors have used the example of the ants to comment on the relationship between society and the individual. Examples are Robert Frost in his poem "Departmental" and T. H. White in his fantasy novel The Once and Future King. In more recent times, animated cartoons and 3D animated movies featuring ants have been produced include Antz, A Bug's Life, The Ant Bully, The Ant and the Aardvark , Atom Ant, and there is a comic book superhero called Ant-Man.
From the late 1950s through the late 1970s, ant farms were popular educational children's toys in the United States. In the early 1990s, the video game SimAnt, which simulated an ant colony, achieved minor success in the gaming world.
Ants are also quite popular as the inspiration for many science-fiction races, such as the Formics of Ender's Game, the Bugs of Starship Troopers, and the giant ants in the film Them!. These races are often referenced as having a hive mind, a common misconception about ant colonies, and benefit from uncommon unity of focus and a willingness for the individual to give their life for the good of the hive. In strategy games, ant-based species often benefit from increased production rates due to their single-minded focus, such as the Klackons in the Master of Orion series of games or the ChCht in Deadlock II.
