What is colony collapse disorder？
Since the winter of 2006, the United States, France, Sweden, Germany, Australia and other countries have witnessed a large number of adult workers in honeycombs. The bees disappear suddenly in a short time, leaving only the queen bee, eggs, larvae and a small number of juvenile worker bees in the hive. Scientists use the "bee colony.Collapse syndrome "to describe this abnormal phenomenon of bees. One of the typical symptoms is that there are no adult workers in the hive.
The second is that there are queens, eggs, larvae and some minor worker bees in the honeycomb.
1、 Typical symptoms
Colony collapse disorder is an abnormal phenomenon found in modern times. First, there are no adult worker bees in the hive, and there are only a few or no
There were no bee carcasses. The second is that there are bee trunks, eggs, larvae and some minor worker bees in the hive, and adults
larva. Third, there is honey and pollen in the honeycomb, and there is no bee stealing and insect pest.
2、 Etiological exploration
1. Disease invasion: disease invasion is not the main cause of colony collapse disorder, but bees will consume honey when attacked by disease
The protein and energy in the bee accelerate the death and disappearance of the bee.
2. Climate warming: Climate warming may be the cause of colony collapse disorder. For example, climate warming can make nectar source plants blossom earlier, may also affect the amount of nectar secreted by plants, and may also make plants unable to blossom.
3. Air pollution: air pollution may be the cause of colony collapse disorder, and the gas composition in the air that prevents the spread of flower fragrance increases
Plus, bees may die because they can't find flowers.
4. Chemical drugs: long-term irrational use of chemical drugs by beekeepers will increase the drug resistance of pathogens
The life span of bees will be shortened by long-term exposure to residual chemicals.
