Honey Bees Repellent Device: Preliminary Experimental Research with the Bees Hearing Sensitivity
Bees are insects that attack, to protect the hive, when they feel threatened. The main objective in this paper was to build an electronic device capable of repelling bees. Thus, a study of the hearing thresholds, of honey bees, has been developed to find out the frequencies range are most sensitive. This knowledge can be important to identify a frequency or a sound capable of repealing them. We also present an electronic circuit developed to build a repelling device able to reproduce a recorded sound or periodic sound. We report also a series of laboratory behaviour experiments, where honey bees (Apis mellifera spp.) had to make the choice between a box where a sound was being played or another box without sound. The experiments were conducted using the following sound frequencies: 100, 150, 200, 300, 400, 500 and 550 Hz; and also, with the sound of three natural predators: the drone, the swallow and the Asian wasp. The honey bees used in the experiments were previously conditioned to go to the box with sound that contained food in order to associate the sound to the presence of food.
