I. Introduction
Honeybees play a very important role in the ecosystem as well as the agricultural economy. According to [1], insects are responsible for about 80% of all pollination activities, of which bees account for more than 80% of total insect pollination activities and honeybees are the most important pollinators. The pollination of honeybees has contributed to maintaining the diversity of plant ecosystems and improving crop yields. Besides, there are many products obtained from honeybees such as honey, beeswax, pollen, etc. and all of them have high economic value. Therefore, in many parts of the world, honeybee farms have been built and are increasingly being expanded.
