Abstract
Bees, wasps, and ants have no specialized receptors for the perception of an electric field. An appropriate response to naturally occurring electric fields in bees and ants is associated with atmospheric exposure, amplified by the approach of the front of a thunderstorm. The primary transducers of mechanoreceptors that respond to displacement are related to the perception of low-frequency electric fields of high intensity by insects. The non-specific mechanism of perception of electric fields is based on irritation by induced currents that flow in the locations of their contact with each other and/or conductive surfaces. The frequency dependence of the electric field sensitivity is determined mainly by the magnitude of the current induced by it and the intensity of its contact action. The magnitude of the current induced in the outer part of the insect body is non-linearly related to the frequency of the electric field. The region with the highest sensitivity to electric fields is close to 500 Hz, which is consistent with the maximum magnitude of the induced current. At the same time, the threshold of the sensitivity to an electric field in wasps is approximately 0.04 kV/m, while in bees it is 0.45 kV/m. Ants react to the action of an electric field of 7–10 kV/m by slowing their movement. Magnetic fields and ionization, which accompany the generation of an electric field whose intensity reaches 15–20 kV/m, do not stimulate changes in the behavior of insects.
