2. The life span of ants is very long. Workers can live for several weeks to 3-7 years, while Queens can live for more than ten years or decades. An ant nest can grow in one place for years, even more than 50 years. 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 morphological science, ants can be divided into two groups: ants and termites. There are many kinds of ants, more than 9000 in the world and more than 600 in China. The life span of ants is very long. Workers can live for several weeks to 3-7 years, while Queens can live for more than ten years or decades. An ant nest can grow for more than 50 years in one place. It belongs to Arthropoda, Insecta, Hymenoptera, Formicidae. The external form of ants is divided into three parts: head, chest and abdomen, with six legs. The eggs are about 0.5 mm long, irregular oval and milky white. The worker ants are small, about 2.8 mm long, brown and yellow. It is easy to find a single ant if you look closely. Both male and female ants are thick. Abdominal fat, head, chest brown yellow, brown in the first half of the abdomen, brown in the second half. The male is about 5.5 mm long. The female is about 6.2 mm long. Social biology ant is a typical social insect, which has three elements of social insect, namely, indivials of the same species can cooperate with each other to take care of their larvae; Clear division of labor; At least two generations overlap in the ant colony, and the offspring can take care of the previous generation in a period of time 1 There are one or more reproctive females (Queens) and a large number of workers and their offspring in the typical nest of life cycle. Males do not exist in the nest all the year round, and the seasons of different species of males are different. Under suitable seasons and climate conditions, males of different nests of the same species copulate with new unfertilized females. Most species build new nests by mating; But some species don't mate and mate on the ground or vegetation. After mating, the males die one after another, and the wings of the fertilized females soon fall off. The first stage of each nest establishment is only for winged females and males. After mating, the wingless female ants (the female ants whose wings are removed by glue) make a soil chamber under suitable conditions to bury themselves, or hide the female ants themselves in other holes, and then prepare to lay eggs. Female ants don't always do this alone, just like bees do. In some species, new nests are established by several newly mated females. Female ants generally do not feed ring the development of their first offspring, and only rely on the unused flight muscles and degradation procts of energy storage substances to proce yolks in their ovaries. Some females may not feed for a year. Eggs usually take weeks or even months to proce. When the eggs hatch, the females feed the larvae with their saliva. The first generation is worker ants, which are usually weaker and smaller after development. These workers emerge from the soil as soon as they emerge. Looking for food for themselves and their mothers. After feeding, the female continued to lay eggs; Worker ants are responsible for all the work of maintaining the whole nest group and supporting the offspring. The second group of workers were larger and stronger. In this way, the population in the nest expands rapidly, and the nest also expands. Wingless females usually proce offspring in the form described above. However, some wingless females do not build new nests, but return to their old nests and become a member of many queens; Some wingless females enter another nest of the same species that has been built to be queen; Some also enter other kinds of nests, and destroy the original Queen. The final host worker ants will also die, which is known as temporary social parasitism; Some wingless females also enslave the workers in their nests. These workers are called ant slaves. When the number of nest and colony increases to a certain extent, the female ant begins to proce fertilized eggs (diploid). After special care and special food, these eggs will develop into a new generation of reproctive females, while the unfertilized eggs (haploid) will develop into males. There are different kinds of situations. After mating, females can survive for 20 years or more, and one female can carry 320 million sperm cells; Workers, however, usually live for three years without being affected by other biological or abiotic abnormalities. It's the season when ants go out of their nests. In South China, it's usually from April to November, and in North China, it's from June to August. As winter approached, the ants graally slowed down and did not like to move, and concentrated in a higher layer of the nest room. During the overwintering period, the freezing point of the organs and tissues of ants decreases, and the muscle activity hardly proces heat and does not feed. Most species of ants do not store food as other insects do before overwintering, but there are still some ants with a storage habit, such as harvest ants 2 Food ants are usually omnivorous animals, mainly feeding on some terrestrial arthropods, including spiders, millipedes, centipedes and insects. Another source of animal protein for ants is to feed on the larvae of other species of ants. Ants also suck plant juices. The honeydew secreted by aphids, scale insects and hornhoppers is also a favorite food for ants 3 There are many kinds of ant nests. Ant nest is the place where ants feed their offspring, resist the external adverse environmental impact and predators, which can be divided into the following types: 1. Most species of the non nest type marching ant family and the two section marching ant subfamily lack permanent ant nest, and only camp together in groups; When camping, the older and stronger workers were at the outermost edge of the colony, followed by the younger workers, with females and larvae at the innermost. These ants usually camp in the crevices between roots or thick branches and soil. 2. The nest type in soil has the most species of ants nesting in soil, and the structure of ant nest in soil changes greatly. Some nests are very simple, with only one exit on the ground, and only three parts under the soil, i.e. waste mp, nest room and main nursery room. Some nests have complex structures, with main and auxiliary passageways, crisscross passageways, multiple nest rooms, larval feeding rooms and queen rooms; After the expansion of the image group, the nest can be built from underground to decaying stumps. 3. Many ants in tropical and subtropical areas often nest on their favorite plants with holes or crevices, which is called ant nest. 4. Wood nest and layer paper nest type wood nest mainly refers to the nest built by ants in which they use stumps, fallen wood sections and other materials. 5. Hanging nest refers to the ant nest hanging or attached to the upper branches of plants, which is similar to the third kind of nest, but this kind of nest is built by ants through complex division of labor and cooperation, mainly including mud nest and silk nest. The silk nest is very strong and not easy to break. Some species use worker ants to carry mud up trees, and use mud, leaves and worker ants' saliva to form mud nests 4 According to the morphology, behavior and social division of ants, they can be divided into three basic grades: male, female (Queen) and worker. At present, there are six kinds of rank names widely used: 1. Male ant: the vast majority of male indivials do not take part in labor, only accept food from their companions, wait for marriage flight, and die after marriage flight. 2. Queen: refers to a fully developed female reproctive ant with the chest structure of Hymenoptera insects and two pairs of wings; Two pairs of wings were removed after marriage. Sometimes the queen is called female. 3. Worker ant: refers to the female ant that has no reproctive capacity, whose ovaries are partially or completely degenerated and have no seminal vesicles. Some ants, such as megacephalus, fire ant and Toxoplasma, can be divided into several sub classes according to the size of body (mainly head): large worker, medium worker and small worker. If large worker ants are mainly engaged in war and defense, they are called soldier ants. 4. Female worker ant: it is between female worker ant and female worker ant in morphology, with or without seminal vesicle, and mostly occurs in parasitic species and evolutionary species. Their abdomen is often not as large as the normal queen, the chest structure is simple, and some wings are very small. 5. Sexual workers: in many species of ants, female ants are replaced by sexual workers. Sexual workers have the morphological structure of workers, but they have the reproctive capacity of Queen. 6. Macrosoma: a grade formed by the extremely enlarged posterior abdomen of female workers. It can be seen as a distorted queen. Generally speaking, almost all ant species change their behavior with the increase of age. Young workers tend to work in the nest, such as feeding and cleaning, while older workers forage, defend and build the nest outside the nest 5 Ant communication ant has a unique way of information exchange, so that its indivials get to know each other in many ways. Chemical communication is the basic way for ants to exchange information. Chemical pheromone is the queen pheromone, also known as Queen substance, released by the upper jaw gland of queen ant and quasi female ant. This kind of "Queen substance" is distributed in the ant colony, which can inhibit the ovary and reproctive system of workers, and make workers work in and out of the colony except oviposition. The second is the secretion of the main jaw gland of worker ants, which plays the role of defense and alarm, also known as alarm pheromone. There is a rectum gland near the rectum of worker ants, which can secrete tracer hormone and mix it in feces to mark the colony territory. The secretion of abdominal gland plays a role in locating close objects. There is a kind of Du's gland near the poison sac. Its secretion plays the role of alarm and summoning, and often secretes from the sting together with the venom. The visual signals of ants are often mixed with chemical communication signals. Ants with large compound eyes have good vision and can see objects several meters away, especially sensitive to moving objects. When food is found, gather your companions to the place where there is food. In addition, ants can also exchange information among indivials through certain activities, such as antennal contact, touching, tasting, grasping, fast moving back and forth, nudging and so on 6 In the nest, other kinds of insects are often found. Generally, beetles are the main species, such as burying beetles and pseudowalkers. These insects living together in the ant colony are called ant guests. The symbiotic ant guest often feeds on the eggs and larvae of ants. The ant guest also learns to master the chemical information system in the ant colony and exists as a member of the ant colony for a long time. The workers in the colony can also enjoy sweet secretion from the body of the ants. The ant guest phenomenon not only occurs in the nest, but also in the territory outside the nest. For example, aphids secrete sweet juice for workers to eat, while workers protect aphids from enemies. Some caterpillars also secrete sweet juice to protect workers. Ant slave refers to the phenomenon that one ant enslaves another ant to work or seek food for its own group. The slave is also called ant worker slave, and the enslaved is called slave. For example, in China, round jaw leaf cutting ant, enslaved paving ant use paving ant to steal food from other ant colony, or help host Ant Attack invaders. The body length of the worker ant is 2.2-2.4mm, light yellow to light yellowish brown, sometimes reddish; More than 300 species have been described in the world, some of which are distributed in warm regions. They are small, reprocing fast, and usually live in the environment where human beings live. Diseases transmitted by ants and their harm to male and female ants

About 20 years

the life span of ants is relatively long, and the life span of indivial ants is amazing, and the life span of queen ants can be as long as 20 years. But a stray ant can only live a few days. This is e to the clear division of labor within the ant colony and the interdependent group structure. This is the basic element of its prosperity

most ants are female, but they are not responsible for fertility, only the queen. A group of male and female ants are also cultivated in an ant nest. They don't work. They just eat and grow. They all have wings. When they mature, they fly out of the nest to mate. After mating, the male ants die quickly. The female ants look for a suitable place to build their nest, take off their wings, become queen ants, lay eggs and develop a new nest

The ant is known to appear as early as Cretaceous, probably evolved from the primitive wasp that appeared in Jurassic. The main difference is that the antennae of ant are obviously geniculate, and the abdomen of wasp is a whole

generally, ants do not have wings. Only males and females (females have fertility, but can only reproce males) have wings when they mate, and females lose their wings after mating

4. General situation of ant growth:

it takes 14 days from egg to small worker ant, through larva and pupa. The egg is white or light yellow, slender, 0.5 mm in size, like a grain of rice. The larvae are milky white, with thin front end and often curved, which is easily mistaken for & quot; Ant eggs;. The pupa is the last instar. The body of the young ants is shortened and does not eat. It is called the prepupa. After the prepupa molts, it is the pupa. The pupae are milky white at the beginning and yellowish brown later. They are often stacked together and mistakenly regarded as & quot; Ant eggs

the life span of ants is relatively long, and the life span of indivial ants is amazing. Some workers can live for 7 days, and the life span of queen ants can be as long as 20 years. But a stray ant can only live a few days. This is e to the clear division of labor within the ant colony and the interdependent group structure. This is the basic factor of its prosperity

Ants are small and United insects that always travel in groups to carry food. Ants are the most common and abundant insects in our lives. What about the longevity of ants? Let's get to know about it

how long is the life span of ants

the life span of ants is very long. Workers can live for several weeks to 3-7 years, while Queens can live for more than ten years or decades. An ant nest can grow for more than 50 years in one place. Ordinary ants can live for less than a month, but Queens can live for several years. Workers only live seven days. Stray ants live only a few days. Termites have longer queens. It can live for about 20 years, which is e to the clear division of labor within the ant colony and the interdependent population structure. This is the basic factor of its reproction

diseases and hazards transmitted by ants

1. Especially harassing children and seriously ill patients. The ant eats pus and sputum, and can also eat dead bodies in funeral homes. Because ants crawl on infectious objects, such as used surgical dressings and toilets, they can mechanically carry various microorganisms, such as Salmonella typhi, Shigella dysenteriae, Yersinia pestis and possibly anthrax

Because ants are often attracted by food, they are in danger of carrying pathogens to food. Ants can bite people, especially patients. It can also cause neonatal umbilical cord infection and sepsis
