Friends who pay attention to the news may have found that the recent news about vespa is constantly appearing, I believe many friends still remember the honeycomb found in Liupanshui, Guizhou, which can be moved by a crane, which is really a real behemoth.
Speaking of wasps, we all know that it is a very poisonous bee, large, poisonous, not to mention people, even large livestock may die under their poisonous needles, and we pay attention to observation and find that it seems that more incidents of vespa attacking people every year occur in the autumn, for example, in October, the wasps have appeared twice to attack people and cause people to die.
The first time was on October 3rd, according to Red Star News, the cause of this incident was that someone took the honeycomb, and then passers-by were attacked by horse bees when they went to the banquet, resulting in one person being seriously injured and treated for more than 10 days before being discharged from the hospital, and one person died that night, the deceased was two couples, at that time, the honeycomb picker was compensated 260,000 yuan.
According to the Chongqing Radio and Television First Eye October 30 report, Chongqing Yongchuan District when doing farm work, was attacked by a group of horse bees, after the incident, the old man was sent to the hospital for rescue, but in the end there was no rescue, and when the old man came out of the funeral, the horse bee attacked the villagers who came out of the funeral again, causing 5 people to be injured again, according to the local villagers, there have been villagers who have been attacked by horse bees before, according to the introduction of local villagers, in the past month, there have been 8 local villagers who have been stung by horse bees.
<h1 class="pgc-h-arrow-right" data-track="7" > is it a wasp or a wasp that attacks a person? </h1>
Here is a clear point, because recently there is a lot of news about wasps attacking people, but according to the observation of the bee tribe editor, the bees that attack people during this time are not wasps, but wasps of the wasp family, which is only a kind of wasp family, and the wasp is generally not many, the size is not as big as many wasps, and the aggression is not as strong as the wasp.
The honeycomb of the wasp is relatively small, the general large plate is so large, a nest of bees is difficult to reach 200, but also prefer to do nests in front of the house and behind the house, if we will not distinguish, we remember that the honeycomb of the wasp is only one layer, and is exposed, usually not done in the hole, but the honeycomb of the wasp is generally wrapped in the outer layer, like to appear in the hole or on the tree, the number is very large, the size is relatively large, can reach tens of thousands of a group, so that I believe that many of our friends are not difficult to imagine, In fact, the horse wasps we talk about a lot of times are actually wasps.
<h1 class="pgc-h-arrow-right" data-track="28" >Why are autumn wasps so crazy? </h1>
As mentioned above, wasps are very male in autumn and very easy to attack people, so why is this time in autumn? Judging from the habits of wasps, the small editor of the bee tribe believes that the reasons for the wildness of the wasps are various.
First: Autumn is the "breeding period" of wasps
Wasps are not perennial insects, as long as we can see the wasps, their life expectancy will not exceed one year, the main reason is that the wasps are insects from solitary to gregarious, belonging to semi-social social social insects, and their entire reproductive process includes a single king survival period, a working bee and a queen bee co-survival period, a queen bee full-time spawning period, a breeding bee breeding period, a breeding bee mating period, a breeding bee wintering period, and a colony extinction period.
The period when we see the queen bee attacking people coincides with the fertility period of the wasp.
In the spring, the wintering queen wakes up, looks for food to replenish energy and then begins to build an independent nest to lay eggs, guard the honeycomb, and after the first batch of professional bees out of the room, the queen bee reduces going out to work, mainly to lay eggs, and when the worker bees can work, the queen bee specially lays eggs, and the bee colony grows rapidly.
In the autumn, as the weather gets colder, the queen bee lays the first male egg, and then the colony begins to breed male bees and queen bees, after the male and queen bees are bred, the queen bee and the male bees will fly out to mate, the male bees that have completed mating will soon die, and the queen will look for a warm place to spend the winter until the weather changes the next year.
There is a problem here, that is, in the autumn, the number of wasps in the bee colony is very large, and the bee colony breeds a large number of male male bees and queen bees, which is the root of the continuation of the bee colony, which requires very high-quality food, and the territorial awareness of the bee colony will be very strong, and the aggression will naturally increase, so the wasps are very crazy in the autumn.
Second: or temperature-related
Because the wasp is a hibernating insect, so the wasp's tolerance to temperature is not strong, and this year's weather changes are more special, it seems that winter comes early, once the temperature is very low, the activity of the wasp will be reduced, especially in the case of extremely low temperatures, the wasp may not even go out to hunt, which will cause a very large sense of crisis to the bee colony, and the bee colony is also easy to expose.
Wasps are not like bees will collect nectar into honey storage for low temperature weather or rainy days or even winter to eat, wasps eat omnivorous, and will not hoard food, so wasps must continue to prey, and the temperature drops rapidly, disrupting the normal life of wasps, causing wasps to become irritable.
<h1 class="pgc-h-arrow-right" data-track="29" >why wasps "choose" sex stings? </h1>
From the above two news we can see that the first one does not seem to be very obvious, but the second news is that the villagers have been stung many times, there is a problem that many friends may not be clear, that is, when the wasp stings, is there a choice?
According to the introduction of local villagers, the road below the honeycomb is there, there are villagers to pass through there, although many people have been stung, but not all of them, so what kind of people are stinged by the wasps? This point is related to three factors.
One is the smell: although the wasp does not have a nose, but the wasp has a very sensitive sense of smell tentacles, the "nose" of the bee, that is, the antennae, if we pass under the honeycomb, the body emits a smell that the wasp does not like, and we are in the case of movement, it is very easy to attract the attention of the wasp, resulting in the wasp attack.
The second is the color of the clothes: just like bees, bees do not like dark things, and are red color blindness, although the habits of wasps and bees have differences, but in biological characteristics, there are still many similarities, so if we wear clothes with darker colors, it is very easy to cause wasps to panic, thus launching an attack.
The third is the speed of movement: the eyes of the wasps are monocular and compound eye structure, compound eyes are composed of many monocular eyes, which causes them to see a wider range, but if it is a stationary object, they can not find it at all, but if it is a moving object, because of their monocular compound eye structure, the object can be seen clearly, so this will also become a reason for the wasp to attack people.
The above is all the content shared by the small editor of the bee tribe today, like friends don't forget to point a note, we will see you tomorrow.
