Chinese bee: Chinese bee has stronger adaptability to temperature than Italian bee. The individual critical temperature distribution is 65438 00℃ and 42℃. When the temperature is higher than 7℃, a few worker bees leave the nest, and when the temperature is higher than 10℃, the number of worker bees leaving the nest increases obviously. When the temperature is higher than 12℃, worker bees can carry out normal collection activities, and when the temperature reaches 40℃, worker bees can still collect from their nests.

Characteristics of division of labor
1, queen bee
The queen bee's social division of labor is to lay eggs full-time, shouldering the social responsibility of reproducing offspring. Its body is very strong, its belly is very big, and its weight is twice that of a worker bee. During the spawning period, the queen bee feeds the worker bees with royal jelly every day to promote rapid metabolism and maintain strong spawning ability. According to expert statistics, the queen bee of China bees can lay 700 to 800 eggs in 1 day, but the most is 1 times higher than this, that is, the queen bee of Italian bees has 1500 to 2000 eggs. From the point of view of weight, the average egg laid every day is almost twice its own weight.
Step 2 hum
Just mating with the queen bee. Drones are male "citizens" in bee colonies developed from unfertilized eggs. They live a unearned life every day, and their only function is to mate with the queen bee. However, when the drone plays this role, it will give its precious life. From this perspective, drones should fulfill the responsibility of social division of labor at the expense of life.
This should start from the whole process of fulfilling responsibilities. Every mating season, sexually mature drones will automatically gather somewhere to fly in the air to attract the queen bee. Once the queen bee appears, all the drones will drive away. After some competition, only one will get the right to mate. Whoever is the biggest and strongest is the final winner, mating with the queen bee. After mating, the drone died immediately because all the reproductive organs were pulled down.
3. worker bees
The social division of labor is the most and the task is the heaviest. It can be said that except for the respective tasks of the queen bee and the drone, other work in the bee colony is undertaken by the worker bees. Worker bees are female organ hypoplasia, but many of their structures are specialized to meet the needs of work. For example, the wind bag in their foregut is specialized into a honey sac for storing nectar.
To brew 1 kg honey, worker bees need to collect 10 kg nectar. It takes 320 thousand kilometers to fly a round trip, about eight times around the earth. Worker bees begin to work as soon as they are born, and the division of labor changes with age.
Under normal circumstances, when worker bees 1~3 days old, they are responsible for keeping the eggs warm and cleaning the spawning room; At the age of 3~6 days, it is switched to feeding large larvae to regulate pollen and honey; 6~ 12 days old, secreting royal jelly and feeding larvae and queen bees; 12~ 18 years old, changed to secrete wax to make spleen and clean the hive; After 18 days old, its task is to collect nectar, water, pollen, propolis and nest door defense.
