Ant [English name]

[Dictionary explanation] Ant, insect name. Most of them live in underground nests and groups, and there are many kinds.

At present, there are 283 genera of 2 1 subfamily (after Bolton 2003). (Compared with 2 1 subfamily system, the new system divides several subfamilies from Formicidae subfamily. ) Ant is a common insect, which is easy to identify. Generally small (0.5mm-3mm), with four colors of black, brown, yellow and red, the body wall is elastic, smooth or hairy. Chewing, the palate is developed. The antenna is knee-shaped, with 4~ 13 nodes, long-handled nodes and 2~3 nodes at the end. The abdomen 1 or 1 and 2 are knotted. Winged or wingless. The front foot has a large spacing and is comb-shaped. It is a corner cleaner (used to clean tentacles). It is a polymorphic social insect. It is estimated that only about half of the ants-about 1 1700 species have been described one by one. More extensive research on ant fauna is needed.

Ants are the most common insects on the earth and the largest number of insect species. Because all kinds of ants are social groups, they were called "ants" in ancient times. According to the classification of modern morphology, ants can be divided into ants and termites.

Ants can live anywhere with their living conditions, and they are the strongest creatures against natural disasters in the world.

Ants live a long life. Worker ants can live for a few weeks to 3-7 years, and queens can live for more than ten years or decades. An ant nest can grow in 1 place 1 year or even more than 50 years.

The shape of ants is divided into three parts: chest and abdomen, and has six legs. Ant eggs are about 0.5 mm long, irregular oval, milky white, and worker ants are smaller, about 2.8 mm long and brown all over. It is easy to find a single ant when you look closely. Both male and female ants are bulky. The abdomen is obese, the head and chest are brown, the first half of the abdomen is brown, and the second half is brown. Male ants are about 5.5 mm long. The female ant is about 6.2 mm in length. The common indoor environment is Pharaoh ants.

Ants are typical social insects with three elements: individuals of the same species can cooperate with each other to take care of their larvae; Have a clear division of labor system; And future generations can take care of the previous generation for a while.

In addition, it should be pointed out that "termites" are not ants. Besides having the same society, termites are also very different from ants in physiological structure.

Biological behavior refers to the adaptive activities that organisms can perceive from the outside. Behaviorism is the study of these activities. Morphology and behavior were first noticed by people, but it was not until the19th century that people obtained the theoretical weapons and experimental means for the study of biological behavior. The theory of evolution has raised the behavior of animals to an adaptive level.

At present, the classification of biological behavior is very confusing. From the perspective of heredity and development, it is generally divided into innate behavior and acquired behavior, namely instinctive behavior and learning behavior. However, this classification method is not commonly used. People generally classify behaviors according to their functions. Unfortunately, this classification method is not strict, and there are a lot of overlapping areas.

[Edit this paragraph] Species and division of labor of ants

Ants develop into completely mutated forms. All ants live in social groups. Generally speaking, there are four different kinds of ants in a group.

Queen Ants: Female ants with reproductive ability, or female ants, are the largest in the colony, especially with large abdomen, developed reproductive organs, short antennae, small chest and feet, wings, wings or no wings. The main responsibility is to lay eggs, breed offspring and manage this big family.

2. Male ant: or father ant. Small head, undeveloped upper jaw and slender tentacles. It has developed reproductive organs and external genitalia, and its main function is to mate with the queen ant.

3. Worker ants: capable ants. Wingless, generally the smallest individual in the group, but the largest number. The compound eye is very small, and the monocle is very small or not. The maxilla, antennae and three pairs of pectoral feet are well developed and good at walking. Worker ants are infertile females The main duties of worker ants are to build and expand nests, collect food and feed young ants and queens.

4. Soldier ants: Soldier ants are infertile males. With a big head and a well-developed upper jaw, it can crush hard food and become a fighting weapon when defending groups.

Ants formed a group, which was also known through marriage and flight. Love at first sight after acquaintance, mating in flight or after flight. The "groom" did not live long, but died shortly after mating, leaving the "widow" queen ant to live a lonely life alone. The queen ant takes off her wings and chooses suitable soil and place to nest underground. She is "fighting alone" and her strength is limited. She can only temporarily build a small room as a place to live, so that her pregnant body has a delivery room. After the eggs in the body mature and produce, the larvae hatch and the queen ant is busy. Every young ant is fed food from her mouth until these young ants grow into adults and can live independently. When the first workers grow up, they dig holes to the outside world to find food, and then expand the building area of their nests to provide housing for more and more family members. From then on, the queen ant who had suffered a lot sat down to enjoy life and became the commander-in-chief of this big family. The work of raising young ants and feeding queens is undertaken by worker ants. But the queen will continue to mate and produce fertilized eggs to breed large families. Her life span can be as long as 15 years. There are many forms of ant nests, most of which nest in underground soil, dig tunnels, secret rooms and houses, and pile up excavated materials and leaves near the entrance to form hills for protection. Some ants use leaves, stems and petioles of plants. Build nests and hang them on trees or rocks. Other ants live in rotten wood in forest areas. More specifically, some ants nest in or near other kinds of ant nests; There is no dispute between the two "families" and they can live in harmony. This kind of ant nest is called mixed ant nest, but it is actually heterogeneous. No matter different ants or ants of the same species, the number of ants in a nest can be very different. The smallest ant colony has only a few dozen or nearly a hundred ants, and some have thousands, while the big ant colony can have tens of thousands or more.

In the broad-leaved forest in the south of China, there is also a kind of jumping-tailed ant. As the name implies, it has a pincer tail and often sticks up, as if eager to try and prepare to attack. He has a strange temper and often deals with trees. It likes to build a nest the size of a football on the tree with sapropel and old bark chewed from the tree, and then mix it with sticky juice from its mouth. The nest is divided into many layers. Male ants, queen ants and worker ants live in it respectively. Children are born in the nest and become an "independent kingdom". At first, there was a tree and a bird's nest. When the ant colony is too big and a new queen is born, the new queen leads some worker ants to build new homes. Sometimes there will be fierce territorial battles. In order to catch other insects on the tree for food, it can run on the branches and leaves of the crown with slender and powerful feet. If two trees are close together, they can skillfully bite each other's hind feet, hang each other down, drift with the wind and shake them to another tree, forming an "ant cable bridge". In order to connect the road between two trees for a long time, the worker ants who undertake the task of bridging can be changed constantly. All the food on the tree was caught. They got off the tree in droves and rushed to catch small animals on the ground. Once the prey is caught, the jumping-tailed ant will inject anesthetic solution with claw needle to make the prey unconscious, and then pull and pull, even a mantis or earthworm weighing more than 100 times can be easily dragged back to the nest by them.

People should be very careful when they pass under trees with such nests. If they are disturbed, they will pounce on you, fall from trees or the sky, attack you and sting you. Everyone should be careful of ants! !

The feeding habits of ants vary greatly among different subfamilies and different species. Generally, it can be divided into carnivorous, phytophagous and omnivorous. Ants work hard most of the year. So where do they go to feed in the cold winter? How do they spend the winter? It turns out that smart ants are prepared before winter comes. They first carry weed seeds so that they can sow next year; At the same time, they carry aphids, scale insects, horned cicadas and gray butterfly larvae in the nest to wait for the winter, and suck excrement from these insects as food (milk honey). Why do ants know that winter is coming? From the perspective of modern science, this instinct of ants is controlled by their annual biological clock, in other words, they make good food reserves during the winter according to the operation law of the annual biological clock.

The creatures formed by interaction with ants have reached an amazing level. There are more than 52 families and 465 species of plants (Jolivet 1996) and thousands of animals (kistner1982; h？ Lldobler & Wilson1990), and a large number of unknown fungi and microorganisms (Schultz &; McGreen 2000; Muller et al. 200 1).

Ants are using extraordinary survival strategies-planting fungi, harvesting seeds, grazing honey-producing insects, nesting, cooperative predation, social parasitism and slavery-which greatly stimulated the curiosity of scientists and the public.

The secret that ants can live in every corner of the world is that they live in a very organized group. They build nests together so that their eggs and offspring can grow safely in them.

There are different kinds of ants, and each has its own special responsibilities. When the queen lays eggs, most of the eggs will develop into females. They are called worker ants. They are responsible for building and defending nests, taking care of queens, eggs and larvae and looking for food. At a certain time, males and new queens will be born. They have wings and fly out of their nests in groups. After mating, the male ants die, and the new queen ants begin to live the life of another group.

The queen ant is the most important member of the ant colony. It is the only one who can lay eggs. This means that it is the mother of all ants in this group. Worker ants feed it, clean its body and take its eggs to another place to take care of it.

Some Australian ants use their worker ants as a living storage box. When worker ants collect a large amount of nectar, a sweet liquid from flowers, and swallow it into their bodies, and their bodies become swollen, they will hang themselves from the ceiling of their nests until other ants need to eat the nectar stored in their bodies.

The soldier ants are foraging in the woodland. In order to find food, they sometimes line up in woodland. They are always hungry, so they will attack almost anything, sometimes even large mammals.

Different ants eat different foods. Harvest ants eat seeds. They collect seeds in the cellar. Leaf-cutting ants eat mushrooms. They take leaves underground to cultivate mushrooms. Some ants store insects called aphids, and they extract a sugary substance from aphids as food, which is very similar to the way humans milk cows.

According to scientists' research, ants lack sugar in caves, which is very unfavorable for their growth and development. In order to find enough sugar, once ants find something sweet, their tentacles will harden independently, which is the nature of ants.

Ants are very social insects and communicate with each other through pheromones emitted by their bodies. When ants find food, they will spread pheromones on the food, and other ants will instinctively drag things with pheromones back to their holes.

When an ant dies, its pheromone still exists. When other ants pass by, they will be attracted by pheromones, but dead ants will not communicate with each other (touch their tentacles) like live ants, so their bodies with pheromones will be taken back by their companions as food.

Usually, such corpses are not eaten as food, because apart from pheromones, each nest of ants has its own specific smell, and things with the same smell will not be attacked, which is the basis for good cooperation with ants in the same nest.

In the process of marching, ants secrete a pheromone to guide the ants behind them to take the same route. If we cross the ant's marching team with our hands and interfere with the pheromones of ants, ants will lose their sense of direction and crawl around. So let's not disturb them casually.

[Edit this paragraph] The persistence of ants

Ants are small and fine, and their perfect physiological mechanism enables them to withstand various tests. In order to set out and return to the nest in a changing environment, desert arrow ants know how to use polarized light emitted by the sun to return to the nest. Amazon ants set routes by memorizing visual references, and this one is a lifetime. After they store a lot of memories, they will call up relevant information according to where they go. Ants have a set of glands in their bodies. They use different chemicals to convey more than 20 meanings.

Microscopic photos of the ant's head "When an intruder is found, all ants remain vigilant. The 422 division rushed to meet. "

"Attention, sisters, attention, there is a caterpillar in front, please take it away quickly. Play it again, there is ... "

Abdominal scraper is a supplement to chemical language. Scraper is a vocal organ, which can rub and send out vibration signals. When a pair of ants marched in the street, the stone gave out a vibration signal. It turned out that an ant was crushed under a stone. Suddenly, a group of ants crowded together and an ant was saved. This signal can also be used to beg for food from each other.

Interpretation of cultural words: ants

[Edit this paragraph] [History of ants]

At that time, it was adjacent to dinosaurs.

Ant is a very ancient insect, its origin can be traced back to 1 100 million years ago, about the same age as dinosaurs. Ants are not only common, but also various. At present, there are about 9,000 species of ants known in the world, and it is estimated that there should be 12000- 15000 species, while there are at least 600 species in China.

There are written records about ants in ancient China. In Er Ya in the early Han Dynasty, there were some words such as ephemera, ant, ant killer and flying ant, but some of the ants mentioned here were mixed with termites. According to textual research, it was not until Er Ya Yi by Luo Yuan in the Southern Song Dynasty (A.D. 1 174) that ants and termites were really described separately. Huainanzi, written around 123 BC, recorded the life history of ants. Later, ancient documents such as Youyang Miscellanies, Taiping Magnolia, Liushougu and Compendium of Materia Medica recorded the ancient people's observation and understanding of ants.

Ants changed history and overlord died in Sri Lanka.

During the struggle between Chu and Han, Sean, the counselor of Emperor Gaozu Liu Bang, used caramel as bait to make ants gather at the smell of incense, forming six Chinese characters of overlord committing suicide in Wujiang River. When the overlord saw this, he thought it was providence, and he was so scared that he couldn't help but sigh: "If the sky kills me, why should I cross the river?" He killed himself with a sword. In the Han family, the story of ants helping spread from now on. Sean used the ant's sweet habit to outsmart the domineering overlord, which is a clever use of the art of war.

A little ant helps you write a book-Ant Philosophy.

In the Old Testament, it said, "You can gain wisdom by observing the actions of ants."

American scholar Jim Ron once said: I have been teaching young people a simple but very effective concept-ant philosophy for many years. I think everyone should learn from ants, because they have four amazing philosophies.

The first part: never give up, the second part: after the rain clears up, the third part: full of expectations, the last part of ant philosophy: do your best. What an amazing philosophy this is.

Ants actually ate an elite German army.

During the Second World War, when Rommel, a famous soldier of fascist Germany, was losing ground to the British army led by Marshal Montgomery, Rommel sent an elite German army to travel long distances, detouring through the primitive jungle of Africa and reaching the rear of the British army. However, at the scheduled time, Rommel did not receive the radio waves from his beloved Sim as scheduled.

Afterwards, the Germans finally understood the truth: their troops were wiped out by the African black thorn Palatine ant. This kind of ant is as big as a thumb and usually lives in Central Africa and North Africa. Every two or three hundred years, there will be a large-scale outbreak. Hundreds of millions of ants migrate long distances in one direction in droves, devouring all edible things crazily. However, there is a mystery that they will never solve: where do such large ant colonies usually gather? Under what circumstances will it suddenly appear?

Don't touch the ants

"Don't mess with ants" continues the excellent tradition of Hollywood animation, with great wisdom in short stories, and directly gives children a real kindness.

Lucas, a boy of 10 years old, is experiencing the most painful thing in his life recently. He just moved to a strange new home and became the target of bullying by his neighbor Steve!

Helpless Lucas had to vent all his anger on the ants in the backyard. He used a water gun to create a big flood in the ant kingdom, which instantly destroyed the ant's home. What Lucas doesn't know is that the "stupid little ant" in his eyes has a complete kingdom, and the angry ant is determined to teach Lucas a lesson after trial and discussion.

The story of walking on stilts-ants actually contain a pedometer (odometer)

A century's conjecture of Dr. Wittlinger in Germany-desert ants contain pedometers (odometers) in their bodies, in other words, they will count several steps while marching and then count back step by step. When the total number of the two matches, it will be "home". To this end, Dr. Wittlinger trained his ants. He cut off the ends of some ants' legs to shorten their pace. Other ants stick bristles on their feet and make stilts. Then, both groups of ants were sent back to the feeding point and returned to the nest. As expected, the ants on stilts could not operate the pedometer enough times because of the step size, so they strolled through the nest like a stroll, froze nearly 5 meters away from the nest, and then began to look for caves. At the same time, the poor ants who were amputated only walked about 6 meters and began to look for caves.

The magical use of ants

Surgical ant

Indians in Guyana, South America used leaf-cutting ant soldiers for surgical suture. They let the ants bite the wound first, then cut off the ants' bodies and replaced the catgut with ants. In addition, the University of Miami in the United States is studying the use of venom from Bolivian ants to make injections for the treatment of rheumatoid arthritis. It is said that ants are still used to diagnose diabetes in some places.

Flood control ant

Ants can also predict floods. Before the flood in the Amazon River, ants gathered information everywhere, made a decision after collective discussion, arranged in a long snake array and moved to a safe place. Based on this, the local Indians learned about the flooded area and moved it in time.

Space experimental ants

During 1983, the American space shuttle Challenger carried out many scientific experiments, one of which was to study whether the tight social structure of ant colony would collapse under the condition of long-term weightlessness.

Programming ant

When people study the activities of ants, it is found that individual ants have coordinated behaviors under the interaction. Although these actions may be simple, only one ant follows the route left by another ant, together they can solve thorny problems, such as finding the shortest path to the food source from countless possible paths. This kind of collective action produced by a group of social creatures is called swarm intelligence. In recent years, more and more researchers try to use swarm intelligence to accomplish various tasks. The foraging mode of ants leads people to find new ways to reroute network communication in a busy communication system and get the best solution.

The gregarious nature of ants

Ants can't survive in a lonely environment. As long as you are alone, or sometimes you just have fewer friends, you will die soon without eating or drinking. Only with enough partners can some of their functions begin to recover.

[Edit this paragraph] Ant control

Ants are very sensitive to temperature, and most of them are active in hot weather. They like sweets, such as cakes.

Honey, maltose, red pond, eggs, stones, skins, dead insects, etc. They can tell the direction and perform very well.

In a hurry, if individual worker ants die, the bodies will be transported back to the ant nest. But they can't stand hunger. Without food and water,

In this case, half of them will die after 4 days and nights.

Experts suggest that household ants can be flooded with boiling water first, and then put into the ditch with washing powder for plugging.

It can also be used as a spray to kill cockroaches and mosquitoes. These drugs have the efficacy of killing little red ants. But the little red ant

It is a semi-social insect, and the general spray can only kill the worker ants, queens and queens who leave the nest in the colony.

These breeding machines are still breeding wildly in their nests. An ant queen can give birth to 600 small ants every second, so it is necessary to kill ants.

The whole building is ideal for collective action. The best way is to choose a palatable one that has no repellent effect on ants.

Drug bait, after the worker ants move the bait back, they can poison the queen, the larvae in the queen's nest and cover the whole nest.

Put out. (Taiming: Taiming's ant bait has special effects on this kind of ant)

Use the characteristics of ants to destroy them;

Ants are mostly in the kitchen where there is greasy food, and we can use this feature to eliminate them. Before going to bed at night, put all the food.

Move to a place where ants can't go, put a piece of fat pork on the ground and prepare a thermos of boiling water. The next morning.

In fact, ants gather on fat and eat well. Don't scare the ants away, just scald them to death with boiling water. This will be eliminated several times.

Clean.

■ Species of indoor ants and their control methods

The harm of indoor ants to the home is often overlooked. After investigation, the indoor ants mainly include yellow ant, big head ant and Rockwell road ant.

Social ants and smelly ants often nest on the roadside, in corners and in cracks in walls. The main ways of harm are stealing food, biting people and spreading bacteria.

Its activity characteristics can be prevented by some physical and chemical methods, such as blocking the activity route and blocking the nest. The condition can be

In some cases, it can also be prevented by biological hormones.

Ants belong to Arthropoda, Insecta and Hymenoptera. Although there is only one family (Formicidae), there are more than 360 genera under it, estimated to be.

About 14000 species, about 300 species in China, widely distributed, from desert to forest, from tropical to cold zone, from plain to mountain.

There are traces. The diet of ants is very complicated, and all kinds of animal and plant carcasses and organic residues can be their food. Therefore, they can

People think that ants have a strong ability to adapt to different environments.

Now, with the rapid development of our urban construction, the living environment of ants has undergone tremendous changes and gradually adapted.

In the densely built and densely populated urban environment, people often invade the room for food and nesting. Because indoor ants will pollute food and decompose it.

Bad buildings spread bacteria and bite people, so they will do some harm to people's lives. We want to better prevent this disease.

To do harm, it is necessary to understand the species and habits of indoor ants, and then put forward some effective measures according to the specific situation.

■ Materials and methods:

Through the investigation and statistics of common pests in families, ants mainly include yellow ants, big-headed ants, Rockwell social ants and smelly ants.

Four kinds. Through the analysis of the characteristics of these four ants, although they are far less harmful than cockroaches and flies, they are still a kind of home.

Hidden danger. Therefore, in view of its cave dwelling and the special chemical odor left on its activity path, the following methods can be adopted to remove it:

○ Wet cloth wiping:

If one or more rows of ants are found to be active, they can be wiped off with a wet cloth and drowned in a basin filled with washing powder water;

○ Washing powder ditch barrier:

Because ants will drown as soon as they enter the washing powder, you can protect an area in this way;

A flood:

That is to say, watering the nest is more suitable for ants to nest in flowerpots.

○ Chemical control:

Dust: Inhaled dust such as silicic acid (silica) powder is usually used to make ants die of lack of water;

Mixture of fenvalerate silicate powder:

This method is an improvement on the previous method, which can shorten the killing time, but it should avoid inhaling powder or dust indoors.

Medium;

Spraying chemicals around the nest mouth and on the ant path can directly contact and kill ants.

This method is easy to cause environmental pollution and resistance. Commonly used drugs are as follows:

Spraying more than 90% trichlorfon stock solution 500- 1000 times;

50% DDVP EC or 80% DDVP EC 1000- 1500 times, 2000-3000 times;

0. 1% pyrethroid kerosene solvent spray, etc.

These methods are effective and quick, but they are not thorough, difficult to eradicate and easy to cause environmental pollution and drug resistance.

○ Poison bait:

Poison bait is a mixture of chemicals and food bait that ants like to eat. According to the mating behavior of ants, a worker ant

After eating poison bait, as long as it does not die in a short time, it can be brought into the ant nest, causing other individuals to die, and the time of death.

Usually within seven days, but the ant pupae may survive without eating, which leads to incomplete ant control.

○ Juvenile hormone analogue bait:

That is, juvenile hormone analogues, such as floxuridine and methoxyprene, are added to the bait.

The concentration of hormone is generally 0.6% ~ 1.5% of the feed weight. At present, it is being developed to add synergist to juvenile hormone analogues to make this kind of medicine.

The law is more perfect.

After the eggshell is ground into powder by burning coke, it can be scattered in the corner or near the ant nest to kill ants. There are ants in the closet.

Ants, you can put some seasoning vegetables such as coriander and celery to drive away ants. Put one in the place where ants often haunt.

Some walnut leaves or cut tobacco and pepper can drive away ants.
