Killer bee? Savior?

Shoot a killer bee

  In the 1970s, in the wild in Brazil, a bee flew buzzing around a woman. She waved to drive, but couldn’t drive it away. The bee finally stopped on the back of her hand wantonly. Too much trouble, the lady slapped the bees to death.
  Unexpectedly, this caused a big disaster. In almost tens of seconds, thousands of bees swarmed out and flew towards her, attacking her, stinging on her face and back hundreds of times. She quickly lost consciousness and was rushed to the hospital. However, the doctor was too helpless, and the lady soon died.
  What kind of bee is this? so smart!
  Usually, when we are bitten by a bee, the red envelope will swell up, and the pain and itching will last for a few days. But sometimes the more you drive, the more it likes to fly towards you. In the panic, we might pick up something and slap the bee to death.
  Shooting a bee to death is extremely simple, and the matter is over. Maybe the classmate who loves animals will feel guilty for failing to kill an innocent bee. But why did this person pay the price of his life?
  It turns out that the lady who shot to death happened to be a notorious African killer bee!
  Why are the African killer bees so powerful? The reason is that when ordinary bees are harassed, about 10% of the members of the colony will participate in the attack, while the African killer bees will all be dispatched. The number of bees in an African killer bee colony may be as high as 800,000. Imagine how scary it is to be besieged by 800,000 bees! People will be life-threatening after 100 to 300 stings by bees. However, in order to ensure sufficient lethality, killer bees often carry out thousands of venom injections.
  What if you run away? How can they give up. Their pursuit time can reach up to half an hour, and the distance can reach up to one kilometer! Even if you dive into the water, they will hover in the air and wait until you come out. Imagine you are in the wilderness, it is better not to mess with these grumpy guys. And killer bees have a strong sense of security. You’d better stay 15 meters away from their hive. A little closer may attract crazy attacks.
The product of human error

  People cannot help asking: Where did the devilish African killer bee come from?
  Ashamed, the African Killer Bee is caused by our mistakes in work.
  It turns out that there were no bees in the Americas a long time ago. Later European immigrants entered the Americas, and European bees were also brought into the Americas. Due to the large number of breeding, European honeybees have gradually become the main bee species in the Americas. However, the Brazilians found that the imported European bees did not adapt well to Brazil’s tropical climate, and their ability to move in high temperatures would be greatly reduced, which was far from satisfying the Brazilians’ needs for honey production and crop pollination efficiency.
  So the Brazilian geneticist Warwick Kerr set his sights on the subspecies of European honeybees—East African lowland honeybees. This kind of honeybee is closely related to European honeybees and has a similar appearance, making it easy to crossbreed. East African lowland bees live in the tropics, with strong activity and reproduction ability, especially strong resistance to pests and diseases. But the disadvantage is that the personality is extremely irritable, and the amount of honey is relatively small. The reason for the low amount of honey production is their strong reproductive ability. They use a lot of honey to feed their offspring instead of storing it. Another reason is that their living environment has less vegetation and cannot collect more nectar.
  Kerr tried to cross the lowland bees of East Africa with the European bees, hoping to produce hybrid offspring that adapt to the hot climate of Brazil and have a higher honey yield. In 1956, Kerr brought 35 queens of East African lowland bees from Tanzania to Brazil. However, his experimental research has not yet begun, and an accident happened-a staff member accidentally opened the cage of the queen bee in the Kerr laboratory, and 26 queen bees seized the door and dispersed.

Killer bee killed a person

  Small mistakes have very serious consequences! Due to the harsh living environment in Africa, these undomesticated (or very low domesticated) East African lowland bees are extremely powerful, and they can even sting to death the honey badger with extremely thick fur that invades their nests, which have been domesticated. The docile European honeybee is no match at all. These 26 queen bees quickly crossed with European honeybees and produced a large number of hybrid offspring.
The madness of killer bees

  Because the genes of East African lowland honeybees are mostly dominant, the offspring of the hybrids mostly show the characteristics of East African lowland honeybees: strong activity, aggressiveness, and rapid reproduction. This quickly brought disaster to the Brazilian people.
  A little boy was surrounded by killer bees. A dog led the bee away. The boy was saved, but the dog was stung to death by the killer bee.

Killer Bee Hive

  Several workers in Brazil angered the “killer bees” there when they were clearing the chimneys. In a short time, crazy wild bees popped out, and immediately a terrible buzzing sounded across the sky. Regardless of whether it is a human or a livestock, as long as it is a moving object, the violent bee colony will attack. Afterwards, people counted that within 3 hours, more than 500 people were stung over 30,000 in total, with an average of more than 60 per person. In addition, many cats and dogs were stung to death. In another incident where the “killer bee” attacked people, more than 1,000 people were injured.
  What is frightening is that these hybrid offspring are not satisfied to live only in Brazil. They gradually replaced European honeybees and produced more hybrid honeybees.
  By July 1985, killer bees appeared on the outskirts of Los Angeles on the west coast of the United States. In order to wipe out these invading killer bees as soon as possible, the authorities did not hesitate to dispatch a heavily armed search team to conduct a close search. Who knows that these killer bees have seized the house beehives one after another, and people had to burn all the hives. However, those who slipped through the net produced batch after batch of “killers” and marched to Florida, California and other places, which made the Americans feel terrified.
  There are frequent incidents of hybrid bees attacking humans. According to incomplete statistics, over several decades, thousands of people have been stung to death by these hybrid bees. The term “killer bee” began to appear. It was compiled into a movie and became the protagonist of a Hollywood thriller, and the exaggerated form of expression on the screen amplifies people’s inner fear.

Without bees, humans will perish

  Killer bees are so vicious, can they be completely wiped out?
  Let’s not talk about this question first, let’s talk about the situation of other bees, because it involves the life and death of our human beings.

Honey from killer bees

  At present, the most important honeybee in the world is the European honeybee, which is one of the earliest domesticated insects. In the past three hundred years, European honeybees have been widely cultivated all over the world due to their excellent honey production and pollination ability, and they are the most important bee species in the world. European honeybees were introduced to China in 1896. Before that, all bees raised by Chinese were native Chinese honeybees. Due to the large size of European honeybees, high honey production, and the ability to produce royal jelly far higher than Chinese honeybees, beekeepers began to raise European honeybees in large numbers. Nowadays, there are very few Chinese honeybees.
  But things are unexpected! In the past ten years, the world has been facing a very serious crisis of declining bee population. Since 2006, there has been a mysterious phenomenon of massive disappearance of bees worldwide. In 2006 alone, 60% of bees in the United States disappeared. This phenomenon of the bizarre disappearance of bees is called “colony failure disorder (CCD)”.
  Beginning in 2006, not only in the United States, but also in various countries around the world, there have been news of the disappearance or death of a large number of bee colonies every year: in Switzerland, about 40% of bees have disappeared; and our country is the largest bee production. In the country, the number of bee colonies has also been reduced by 10%…The phenomenon of colony exhaustion disorders has continued to this day. What is worrying is that there is no effective way to curb this situation.
  The causes of bee colony failure may be caused by a variety of factors. Scientists speculate that these factors include: pesticides, parasites, viruses, etc.-due to the widespread use of pesticides, according to statistics, pollen collected by bees may contain up to More than 6 kinds of pesticides. The chemical substances in the pesticides cause poisoning and death of bees; in addition, there are some parasites on bees, such as Varroa mites, which can carry and spread a variety of pathogens, causing the reduction of immunity and activity of bees, and ultimately leading to death There is also the invasion of viruses. For example, in 2005, the United States discovered the LAPV virus in its imported Australian bees. This virus once caused a bee crisis in Australia. LAPV is just one of many viruses that can infect and kill bees.
  What impact will bee colony failure have on human life?
  According to data from the Food and Agriculture Organization of the United Nations in 2007, about 85% of the crops that people mainly plant, about 80% of the angiosperms in the world are pollinated by insect vectors, and the most important pollinator is bees. About 75% of the flowering plants in the world rely on the pollination activities of birds, bees and other pollinators to complete their reproduction. Therefore, the stability of the number of bees is of decisive significance for the production of food crops, fruits, nuts and flowers. There is a popular saying: If bees disappear from the world, humans can only live for another 4 years.
  For this reason, the exhaustion of the bee colony is an important issue that we are encountering, and the top priority now is how to rescue the “beneficiary” who is on the verge of extinction.
Survival after the killer bee

  Just as the bees were on the verge of extinction, scientists found a way to save them. This is the killer bee!
  It turned out that as early as 1994, killer bees were introduced to Ireland and later hybridized with local European bees, and their scale expanded rapidly. Killer bees quickly caused 4 deaths, and the number of assaults reached 10,000 in a year. The Irish government had to mobilize police to destroy more than 2,000 killer bee nests.
  Unexpectedly, in September 1998, Hurricane George hit Ireland, causing the number of bees in Ireland to decrease drastically by about 90%, and the numbers of killer bees and European bees were greatly reduced. The Irish launched an operation to restore the number of bees in Europe. As for the killer bees, of course they wish they would go extinct. However, the killer bee has slowly regained its scale relying on its extremely strong reproduction ability. A few years later, it reached the level before the arrival of Hurricane George, but people were surprised to find that the killer bees became “gentle”—sometimes you still rock the killer bee’s hive, or even kick their hive, They are actually indifferent. The number of killer bees attacking people has also dropped to 500 per year, about one-twentieth before the hurricane.
  Is this the killer bee we know? There is no doubt that in the 10 years since entering Ireland, killer bees have evolved in their habits, and they have gradually become as docile as European bees! Some people think that the living environment of the Irish killer bee after the hurricane has been destroyed, and the killer bee colony that tends to attack people has been extinct in large numbers. Among the killer bees, the more gentle ones are for finding food instead of using a lot of energy to attack humans. The colony of bees survived and reproduced. Others believe that the population density of islands is so high that killer bees are used to coexisting with humans and become less repellent to humans.
  We don’t know the real reason, but we are very clear about one thing. Humans can consider raising killer bees!
Is the devil going to become an angel?

  In fact, the killer bee’s violent temper concealed many of its excellent characteristics.
  As mentioned earlier, first of all, the killer bee has excellent environmental adaptability. European honeybees are not adapted to the high temperature environment of the equator, but the killer bee is different. It reproduces a large number of offspring rapidly in Brazil, and it only takes more than 20 years. After time, it spread to the American continent, which has a huge span of latitude, which shows its strong environmental adaptability. The climate varies greatly across the world, and perhaps killer bees can meet the needs of bees in many places. Of course, if it is to be promoted globally, the harm of biological invasion must be considered.
  Another is the powerful reproductive ability of the killer bees. The reproductive ability of the killer bees is several times that of the European honeybee-they are grouped three to four times a year, while the European honeybee only grouped once a year. This is a method worth considering in today’s world where bees are declining. Breeding killer bees to restore the number of bees as soon as possible.
  Then there is the powerful activity of the killer bee. Because the environment for collecting nectar by lowland bees in East Africa is quite dangerous, their efficiency in collecting nectar is extremely high, and the time for collecting nectar is quite long. This excellent characteristic has also been passed on to killer bees, causing killer bees to gather honey faster than European bees, and their honey production far exceeds European bees-whether it is for pollen transmission of plants or bee breeding industry, this Both have important meaning.
  The last and most important point is that killer bees are far more resistant to diseases and pests than European bees. Everyone who breeds European honeybees knows that the parasitism of Varroa mites is always the most troublesome problem. And because killer bees often take the initiative to clean their appearance, the parasitic rate of Varroa mites is only half of that of European bees. European honeybees are susceptible to many diseases, such as bee sporeworm disease, paralysis, European larval foul disease, cystic larval disease, bee pupae, etc., while killer bees have stronger resistance to these diseases.
  Scientists have been studying the phenomenon of bee colony failure for more than ten years, and the real cause is still unknown. The research on killer bees is underway. Perhaps with the help of its excellent genes, it can be directly cultivated on a large scale, or it can be crossed with our existing bees, or its genes can be extracted by genetic technology to help us get through. This global crisis of bee shortage.
