Entering 2021, many rare animals and plants are rushing to burst out, giving us a big silver screen performance exclusive to them from the beginning of the year to the end of the year. And as the audience and director, when we see such a vibrant scene, we naturally reap not only psychological pleasure, but also benefit ourselves from the opposite side. I have to say that there are too many new things that have appeared this year, such as the living fossil "fairy shrimp", the jackal of the first of the four beasts, the sambar deer of the "vampire deer" and the "sacred deer" white-lipped deer, the endangered species Huabai and "rebirth" that disappeared for 122 years... Wait a minute.
A rare species was found in Tonglu, Zhejiang: the Tianmu stink frog
But the good news is far more than that, a few days ago, Guizhou LeigongShan came with even greater good news: a strange insect was discovered, refreshing a new record for Chinese insects! What kind of species is this? Why is it so special, just listening to the name is very interesting: the breasted bearded wasp, so why is it called a beneficial insect by experts as a "parasite"? With these questions in mind, let's talk about the Rubik's Cube in detail.
<h1 class="pgc-h-arrow-right" data-track="7" > the "Noah's Ark" of rare species - Guizhou Leigongshan Nature Reserve</h1>
Located in the southeast of Guizhou Province, Leigongshan Nature Reserve has been established for 39 years since its establishment in 1982, and was upgraded from a provincial-level nature reserve to a national nature reserve in 2001. According to relevant statistics, the area of Leigong Mountain Nature Reserve is very wide, the area is 50,000 hectares, the highest altitude is 2178 meters, and the vegetation in the mountainous zone shows a vertical distribution of vegetation and a wide variety of species. Its climate belongs to the humid mountain climate of the central subtropical monsoon, with no severe cold in winter, no severe heat in summer, and abundant rainfall, which is more blessed by the local ecology.
According to relevant statistics, the primary forest of Leigong Mountain is very rich, with a total of nearly 2,000 species of animals and plants growing in the reserve, up to 43 species of plants listed under national protection, 1,390 species of plants that have been identified, and 518 species of animal resources. Among them, among the 132 families, terrestrial vertebrates and insects are the most numerous, with 224 species and more than 600 species, respectively. In addition, its forest coverage rate is as high as 83%, so whether it is animals or plants, its richness and the ecological situation of Lei gong Mountain Nature Reserve are vividly reflected.
It is worth mentioning that in fact, in recent years, leigong mountain nature reserve has frequently had good news, and many species have been found, such as: the crested eagle, a national second-level protected animal
National Grade II protected animal willow leaf chicken (spoon chicken)
Wild black bears
As early as 10 years ago, Lei Gongshan has broken the record of 20 new species that have broken the record, which is not, this discovery is another "big thunder". Extremely rare, it is still the first time in China, and its "distant relatives" have only 3 species in China before, and this mysterious species is the breasted bearded wasp. It may seem that many people will feel like a mosquito, but in fact it is indeed a kind of insect. It is a parasite, but is called a beneficial insect by experts. Its body is full of mysteries, what kind of creature is it?
<h1 class="pgc-h-arrow-right" data-track="37" > to refresh a new record for insects in China: what are the characteristics of the large-bearded bee that surprised the Leigong Mountain in Guizhou? </h1>
It is reported that the discovery of the breasted bearded wasp was also an accident. In the process of cooperating with the Forest and Grassland Disease and Pest Control Station of the State Forestry and Grassland Administration, the Guizhou Academy of Forestry sciences and the Guizhou Leigongshan National Nature Reserve Management Bureau to carry out the investigation of the parasitic natural enemies of the Leigongshan pest, the experts found such a peculiar insect, so they sent it to the identification experts, and finally concluded that this insect was a new record in China - Megastylus (Dicolus) pectoralis.
In terms of species, the pectoral bearded wasp belongs to the genus Of the macrocephalus of the subfamily Arch-faced Bee of the order Hymenoptera, and previously there were only 3 species in China, namely the yellow-bellied Large-bellied Wasp (M. flaviventris Sheng & Sun), M. Maculifacialis Sheng & Sun), black-breasted large-bearded bee (M. Nigrithorax Sheng & Sun), now with the discovery of the thoracic bearded wasp, not only has new species been added to Lei Gong Mountain, but also China's insects have set a new record. Its far-reaching significance, coupled with the fact that this insect has a great effect on inhibiting pests and diseases, the future development of Lei Gong Mountain is immeasurable.
Like all bees, the bees look gentle and kind, but they all live on parasitism on other insectoids, especially during the larval stage. Therefore, along with its own growth, it will also kill those parasitic insects invisibly, but generally this species chooses pests. Therefore, invisibly it has also done a good thing, and it is a beneficial insect in general.
In addition, the spawning of the breast-bearded wasp is also very popular. They can lay two types of eggs, a fertilized egg and an unfertilized egg. Most of the former are born in the individual larger pests so that they can thrive and develop, and the development is the daughter, while the latter is born in the individual small pest, and the development is the son. The breeding of this species depends on the daughter, so the male wasp born will not lay eggs, has no pest killing effect, so it is basically useless.
<h1 class="pgc-h-arrow-right" data-track="38" how to protect the large-bearded wasp >? </h1>
The pectoral bearded wasp is the first discovery that has innovated the species record in our country and is particularly precious to us. Its significance lies not only in the rare characteristics, but also in the importance of biological checks and balances on pests. For the current situation of more and more attention to environmental protection, if you can eliminate pests without medication, I believe that the breast bearded wasp should be the best solution.
How should I protect the bee? First of all, we can plant honey-source plants for bees, spray honey, and correctly select insecticidal drugs as we protect all species of bees. On the one hand, it creates a better growth and development environment for the growth of the bees, and on the other hand, it uses chemical agents that do little harm to the bees to protect them while reducing the number of pests.
In any case, the discovery of this species is indeed good news. Leigong mountain nature reserve and even Guizhou are areas with rich diversity of wild animals and plants in China, and in recent years, there have been many rare species, and the protection effect is still good. It is believed that the protection of the breasted bearded wasp can also be the same, and there may be more wild animals and plants in the future. For us, isn't such a situation exactly what we hope for, after all, people and nature have mutual interests!
