Regulation of humidity and ventilation: Humidity of the hive, which gives honey its protective quality, must be kept within a certain limit. If humidity is over or under a normal limit, then the honey will get spoiled and loose its protective and nutritious qualities. Similarly, temperature in the hive has to be 320 C for 10 months of the year. In order to keep the temperature and humidity in the hive within certain limits, a special "ventilation group" is appointed.
In a hot day, bees are easily observed ventilating the hive. The entrance of the hive fills with bees and by clamping on the wooden ground, they fan the hive using their wings. In a standard hive, air entering from one side is forced to leave from the other side. Extra ventilator bees in the hive work for pushing the air to all corners of the hive.
The ventilation system is also useful in protecting the hive from smoke and air pollution."And that We have subjected them to their (use)? of them some do carry them and some they eat: And they have (other) profits from them (besides), and they get (milk) to drink. Will they not then be grateful?"(Surah Ya-Seen (Ya-Seen), 72-73)
Health system : The effort of the bees to preserve the quality of the honey is not limited with humidity and heat regulation. A perfect health system in force within the hive also keeps under control all events that may result in the origination of bacteria. The main purpose of this system is removing all substances subject to cause bacteria production. The basic principle of this health system is to prevent foreign substances from entering the hive. To secure this, always two guardians are kept at the entrance of the hive. If a foreign substance or insect enters the hive despite this precaution, all bees take action to remove it out from the hive.
For the bigger foreign objects that can not be removed from the hive, another protection mechanism is started. Bees produce a substance called "propolis (bee resin)" for these kind of situations. They produce it by adding some special secretions to the resins they collect from trees like pine, poplar and acacia. Propolis is a special substance in which no bacteria can survive. The bigger foreign objects in the hive are enveloped with a 1,5 mm thick propolis, and are thus isolated from the hive.
The same bee resin is used to patch the cracks in the hive. After being applied on the cracks by the bees, the resin reacts with air and forms a hard surface drying in a very short time.
It is quite obvious that the system employed by the bees for the protection of the hive requires great consciousness and intelligence. What is more interesting is the special feature of the propolis, secreted by protection purposes by the bees, not letting any bacteria survive in it. Even though we assume that bees secrete this substance "consciously" to cover foreign substances, how can we explain that bees give an antibacterial quality to this secretion? Can you - who have a more developed intelligence than the bee - give antibacterial quality to any secretions of your body?
