How many kilometers can bees fly in a day?
Bees fly at a speed of 20-40 km/h, with an altitude of 1 km, and the effective range of activities is within 2.5 km from the nest.
Bees live in groups. There are three types of bee colonies: queen bees, worker bees and drones. There is one queen bee (in some exceptional cases, there are two queens), 65,438+0000 to 65,438+05000 worker bees and 500 to 65,438+0500 drones. In order to get food, bees keep working, collecting honey during the day, making honey at night and pollinating fruit trees, which is an important medium for crop pollination.

The survival crisis of bees in China;
With the increasing number of Italian and other exotic bee species introduced into China, the distribution area of bees in China is getting smaller and smaller, and it is shrinking year by year. Especially in some plains, hills and low altitude areas, Chinese bees are basically or completely replaced by exotic bees.
According to Beijing Science and Technology News, the number of Chinese bees in Beijing alone has decreased from more than 40,000 in 1950s to less than 40 at the beginning of this century, which has reached an endangered level. Terrible is that once the Chinese bee is completely extinct, it will affect the changes of all related plant ecosystems. The common problems encountered by Chinese bees are that the queen bee is difficult to mate, the colony frequently loses the queen, and the population declines obviously.
