ACOUSTIC CONTROL OF EXPERIMENTAL HIVE IN JANUARY 2020



January 10, 2020. The weather is warm - It's about + 1- +2 degrees Celsius... The bees are in the upper part of the hive. Candy, which we gave, already ended in almost all families ... Some bees were found on the snow ... Due to the hot winter,  it is possible that a cleaning flight  took place, or the bees  throw out the dead ones...




In the control hive it was carried out an acoustic control, using Apivox Smart Monitor . We made a cut in a textile cover of the moss pillow. This made it possible to insert the smartphone into this "pocket" with the microphone facing down. As a result - the maximum possible sound contact without raising the pillow. Bees were active enough, but the wired microphone practically does not hear them !!!






Bees are quite active and this can be seen on the diagram.


Screenshots of results of control in several modes also confirm the same - we used General State Control mode and  Brood Control mode.








It can be seen that after the anxiety of the bees, the signal in the area of ​​active in-hive works increases. However, there are no signals associated with the work of the wings. And there is no any signals of excitement ...







The app in Brood Control mode show, that prior to the anxiety, the signals were clear and that all of them were in the diapason of in-hive works. The anxiety - opening the hive, control of "mites drop", led to extension of the range of signals and their partial falling into the area of the signals, which the bees emit when they work with brood... But their strength is such, that the average value is about zero. And after we stopped working with this family, the signals again began to move into the range of in-hive works...  So, we should say, that most likely, there is no open brood in the family...
