Many people believe that bee is one of a kind bee and they are all the same. Only here in the world there are about 21 of the thousands of species that live in all parts of the world except Antarctica. These insects sting, but bring humanity a huge favor. A large number of people keep them in their home areas to obtain the honey, which has many useful properties and has no limitations in shelf life. Also, these insects spread pollen of plants and greening our planet, providing us with a large amount of food. As you can see, these creatures are very important to us, but there is bad news — recently, the US has recorded the extinction of bees. You can guess what the consequences would be?
Life of bees
A record number of extinct bees told Gizmodo. Reporters learned about this, looking at the results of an annual survey conducted by researchers from the University of Maryland (USA) among more than 3,000 beekeepers. The total number 276 832 they own a colony of bees each year to inform scientists about changes that are happening in the lives of these insects. It turned out that from April 2019 to April 2020, U.S. beekeepers lost 43.7% of the honey creatures.
Usually bees in large numbers are dying in the winter during cold weather. But this time, the proportion of extinct to winter bees was only 22,2% in previous years the percentage was at least a 6.4% increase. Most of the deaths of the bees we had in the summer time — such a mortality scientists have not seen for 14 years. The survey showed that last summer killed 32% of the bee population, and is 10.4% above the average.
The effects of heat
The main reason for the high mortality of bees is considered a heat wave the summer of 2019. Then earth satellites the European Agency launched in the framework of “Copernicus” in 2014, has recorded a record high temperature — jump took place in July. High temperature could affect the reproduction of bees, and also lead to their starvation. The fact that the flowers the nectar of which they feed, blossomed at different times and the insects were not ready to such changes.
Also, over the years, researchers have noticed an increase in populations of varroa (Varroa) and parasitic mites, which penetrate into the organisms of honey bees and literally live by them. They suck the energy of insects feeding on their fat bodies. Most often the parasites attach themselves to the sinuses between wings of the bees on the reverse side of the abdomen and between the legs. Most of the bees not able to get rid of parasites, but specimens of some of the colonies can shake them off with each other.
Do not forget that the life of bees is affected by the pollution of our planet. Recently in Argentina was found a bees nest made out of plastic trash. This material is clearly unsafe for insects, because inside the plastic sockets were found dead larvae and adults. It may well be that the presence of such dwellings also affected the survivability of the tiny creatures.
The consequences of the extinction of bees is very bad, because mankind is highly dependent on their activities. According to data provided by researchers from the University of Maryland, in the USA, bees annually help pollinate crops worth about $ 15 billion. It turns out that about a third of the food that we eat every day, obtained thanks to the life and work of bees.
