Implementation of an electronic system to monitor the thermoregulatory capacity of honeybee colonies in hives with open-screened bottom boards

Electronic systems are not widely used for measuring biological variables in beehives despite the importance that honeybees have for both the environment and humans. A better understanding of bee colonies is needed in order to prevent certain dangers that threaten the bee population. In this study, we have developed an electronic system based on the Arduino Open Hardware platform, to which we have added temperature and humidity sensors to adapt the system to the particular conditions of beehive management. The system has been used to record changes in temperature and humidity inside hives and assess bees' thermoregulation adaptability within colonies in hives with opened-screened bottom boards; an interesting management tool for controlling the harmful Varroa destructor mite as compared to beehives with conventional closed bottom boards. The results revealed that bee colonies were able to thermoregulate in hives with open anti-Varroa bottom boards to the same degree as those in conventional bottom board hives even under winter conditions in a mediterranean climate, thus indicating that there are no additional risks associated with the use of open-screened bottom board models.
