In fact, this question is the same as why people get sick.
One: Environmental stimulus
Bees feed on nectar and pollen of plants, which is of course closely related to nature. Bees have limited self-regulation ability, so they get sick.
China mainly domesticates Chinese bees and Italian bees artificially.
There are fewer diseases of Chinese bees, but the pests and diseases are more serious, such as cyst disease and nest worm. If not handled properly, it will be in danger of extinction.
There are many diseases of Italian bees, but the disease is mild, such as mite damage, chalk disease, metamorphosis and so on.
Conclusion: Chinese bee has stronger disease resistance than Italian bee.
Two: the hive factor
Honeycomb is the home of bees, so it is also a factor that causes bees to get sick.
The beehive is generally about 2 cm thick, closed, crack-free and light-dense. Bees like the dark environment, which is also good for heat preservation.
The hive can't touch the ground directly to avoid getting wet. The beehive is placed south, and the backlight is sufficient.
Three: food poisoning
It is fatal for bees to eat honey plants sprayed with pesticides.
In order to pursue economic benefits, some beekeepers often pick honey when they see it, and artificially feed white sugar when there is no flowering period. The nutritional components of syrup are relatively simple, which is definitely not as good as honey, and may cause indigestion and absorption to bees.
In fact, it is not terrible for bees to suffer from pests and diseases. Only by doing the relevant defense work well can the honey yield be improved.
Welcome friends who like bees to discuss and study together.
