Familiar with the coming of ants and how ants came

Queens generally do not leave the nest unless the colony is too large and has to be divided into two nests, or the nest is abandoned, or the nest is left at the beginning of mating.

Red fire ants invade our country.

Taiyuan News Network 2005-03-01 11:12 Shanxi Business Daily.

The world's "most dangerous ant" has invaded our country. The General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China issued an urgent notice that ports across the country should be strictly guarded.

On February 27, experts from the Institute of Zoology of the Chinese Academy of Sciences were vigilant: "According to its suitability, red fire ants may threaten 25 provinces, municipalities and autonomous regions in China, and we must be highly vigilant!" ”

According to Zhong Junhong, a member of the Guangdong Red Fire Ant Expert Group, "Red Fire Ants are native to the south.

Beauty, in entomology, is a 'close relative' of the common ant, and its adult body is 3 to 6 mm long, which seems insignificant, but its harm is not known to be much greater than that of the termites we hate. ”

One of the hazards is that red fire ants will eat the seeds of many crops such as sunflowers, soybeans, corn, etc., or "graze" aphids, mealybugs and other pests on crops, indirectly harming crops.

The second hazard is that the teeth of red fire ants are strong and sharp, and they will bite through wires and cable sheaths, or fill in sediment into electrical equipment, resulting in short circuits.

Third, red fire ants also seriously endanger human health. Experts said: after being bitten by red fire ants, there will be erythema, redness and swelling, pain and itching, and sometimes it will cause high fever and pain, and some people with sensitive constitutions may have anaphylactic shock reactions, and in severe cases, they will die.

As for how red fire ants came to China, there is a basic speculation in China's scientific community: it may also be brought in through exotic plants; The main ones are related to the United States, Australia, New Zealand and other countries where there are frequent personnel exchanges on the mainland.

Experts suggest that for all potential distribution areas, quarantine work should be intensified, and preventive measures should be taken in advance to prevent them from carrying and invading with nursery plants, turf, soil, equipment and tools, containers, etc. According to "Liberation**".

Ants are known to have appeared as early as the Cretaceous period, probably evolved from the primitive wasp that appeared in the Jurassic, with the main difference being that the ant's antennae are distinctly knee-like curves, and the wasp's abdomen is a whole. Ants generally do not have wings, only males and females (females are fertile, but can only produce males) have wings when mating, and the females fall off when they mate.

Ants are social insects that are close relatives of wasps. The head is usually broad, antennae knee-shaped, 4-13 segments. Compound eyes are small, withdrawn, and 3 in one eye, located on the top of the head. The mouthparts and feet are well developed, and the tarsal joints are 5 segments.

Sexual individuals have 2 pairs of wings, and worker ants are usually wingless. The basal ventral segment is markedly constricted, forming the ventral stalk. The ventral peduncle is 1-2 segments, and there are 1-2 nodular protrusions on the back of each segment.

Most species are polymorphic and are social insects. Some species are carnivorous, preying on insects, spiders and other small animals; Some are herbivorous, feeding on seeds, fungi and other plant matter; Some are omnivorous.

Red ants are very good at fighting, but they are very lazy, they are not willing to look for food, they are not willing to raise children, even if the food is next to them, they will not eat, and their food, clothing, shelter and transportation have to be done for them by servants. In order to achieve their goal, they go to rob their neighbors of different species of ants, such as black ants, snatch other people's pupae and transport them back to their nests. Soon after, the snatched chrysalis molted and became an active servant in the house.

When the hot June and July came, the red ants set off from their homes, and the whole team was more than 5 meters long, blindly searching for the target - black ants. As soon as the target was found, the leading ants stopped, and the other ants also strode after them, and after confirming that the situation was true, they all rushed into the house of the black ants, and after a fight, the victory went to the red ants, who bit the chrysalis with their big jaws and hurried back home.

The distance of the red ants' expedition depends on the distance of the black ant's home, and they do not choose the path they go on, and they do not have a clear destination. They can all be crossed except by waterway. But their way back is steadfast, and no matter how crooked and dangerous the road they came out out of, they go back the way they came.

They only know the way they were.

According to Dr. Edward Wilson, the first authority on entomology and antology, the first ant wasp ant subfamily appeared 100 million years ago and evolved from a non-social wasp in the southern hemisphere, and all modern ants are wasp offspring. The social social behavior of the group should have evolved independently 12 times in Hymenoptera. Amber fossils of wasp ants were reported in 1967 and Wilson considered them "a near-perfect sequence between modern ants and non-social stinging wasps."

The above information is quoted from the biographical book "Ant Empire" by Erich Hoyt, translated and published by Hainan Publishing House. Wilson's monographs on social insects, "Insect Society" and "Ants", should be discussed in more depth, but I don't know if there is a Chinese translation.

Ants are mainly divided into black ants and termites, and the difference between the two is still relatively large. Black ants share the same ancestor as wasps, while termites have the same ancestor as cockroaches.

Ants are a member of the insect family, and they have a highly developed social organization and coordination skills. But how exactly did they come about? According to paleontologists, the origin of ants can be traced back to the Cretaceous period hundreds of millions of years ago.

At that time, the climate on Earth was very hot and humid, and the rich rainforest environment provided a good living environment for ants.

However, ants are able to spread widely on the planet thanks to their ability to reproduce. An ant fuses the genes of the mother and the father, and the eggs laid after breeding hatch a wide variety of ants. The ant queen can hatch thousands of eggs in a single ovary, which in turn can be spiked to continue to reproduce.

As a result, a variety of different ant species have gradually emerged, such as loyal soldier ants, labor ants, and even queen ants.

To sum up, the reason why ants have been able to spread the earth and gradually evolve into what we are familiar with today is not only supported by a rich living environment, but also thanks to the discovery of their extreme reproductive ability. With these advantages, ants continue to conquer new territories around the world and co-evolve with other creatures.

Origin x0d x0a thought back then, it was neighbors with dinosaurs. Ants are a very old insect whose origins date back 100 million years, about the same time as the dinosaurs. Ants are not only common and have a wide variety, there are about 9,000 species of ants known in the world at present, it is estimated that there are more than 600 species of all kinds of less than 600 species in ancient China, there are written records about ants very early in ancient China, written in the early Han Dynasty in the "Erya" there are words such as mayflies, ants, fighting ants, flying ants, etc., but the ants referred to here are mixed with termites.

According to research, it was not until the Southern Song Dynasty Luo Yuan wrote "Erya Wing" (1174 AD) that ants and termites were really described separately. The Huainanzi, written around 123 B.C., has an account of the life history of ants. Subsequently, the documents of the past dynasties, such as "Youyang Miscellaneous Tales", "Taiping Yulan", "Liushu Gu" and "Compendium of Materia Medica", all recorded the observation and understanding of ants by the ancients.

American scholar Jim Rohn once said: For many years I have been teaching young people a simple but very effective concept - ant philosophy. I think you should learn from ants because they have a surprising four philosophies.

Part 1: Never Give Up, Part 2: Plan Ahead, Part 3:

Looking forward to it, the last part of the Ant Philosophy: Do your best. What a compelling philosophy.

Ants are known to have appeared as early as the Cretaceous period, probably from the primitive wasps that appeared in the Jurassic, and the current ants are all born from the queen. The queen ant is not equal to the female ant because the average ant is female, but they are not responsible for reproduction, only the queen ant gives birth. An ant nest also cultivates a group of male ants and female ants, they do not work, just eat and grow, have wings, and fly out of the nest together to mate after maturity, the male ants die soon after mating, and the female ants find a suitable place to make a nest, eat their wings, become the queen, lay eggs and develop a new nest.

It relies on its antennae to sense, so it must have a delicious smell that provokes it.

The queen ant mates with the male ant, and after laying eggs, it is cared for by other ants in the nest and produced.

Of course, ants are born by ants, and there's no doubt about that, hehe, and as for how the ants came about, just like other creatures on Earth, they evolved from the condensation and chemistry of molecular clusters. American biologists have put forward the idea that ants probably first appeared on Earth between 1400 million and 16.8 billion years ago, and that they diverged on a large scale about 100 million years ago, and that the prosperity of the ant family may be closely related to the emergence of angiosperms.

The discovery was published in the new issue of the journal Science.

I don't know if it meets your requirements.

Are you asking how ants evolved, or how do ants reproduce? Speaking of reproduction: the ant family has a "production machine" that can generally produce more than 100 larvae per second (there are many kinds of ants, some may be more than 50, and some may be two or three hundred), and it is the queen ant.

The queen has a large abdominal cavity that can hold tens of thousands of eggs. At all times, the queen ant lays young eggs from its tail, and the male ants in the colony mate with it regularly (usually a fixed one, unless there is a male ant war). ), and these eggs are carried by worker ants (asexual ants) to a fixed nest for development and feeding.

The next generation of ant families produced There are these types, male ants (males), queen ants (females), worker ants, and soldier ants (asexual) Worker ants are not sexually mature, only size. And when the male ant and the queen reach maturity, they become winged adults. And then a large number of winged adults will gather outside the nest to pair freely and dig a small nest together, and once they are paired, they will shed their wings and mate in the nest they dig to become a new generation of royalty, and the female will gradually grow in size and become a huge production machine.

And the male ant will turn into a giant ant king that is bigger and stronger than the soldier ant. Their newly born worker ants expand their nests and territories.

Just say that my mother gave birth to it.

There is an ant hole nearby, and the fragrance comes.

There are eggs laid by ants that hatch.

Ants her mother gave birth to her. Speechless.

Ants are born

That's an interesting question.

Very interesting question, it is recommended to inquire about biological evolution.
