SHORT COMMUNICATIONS Dependence of the Structure of Electrocardiogram on Temperature in the Honeybee E. K. Es’kov Russian State Agrarian University for Education by Correspondence, Balashikha, Moscow oblast, 143900 Russia Received October 17, 2003 Key words: worker bee, queen bee, drone, heart, electrical oscillation, heart function, hyperthermia, hypothermia. The amplitude and temporal structure of electrical exceed those in drones by a factor of 1.2 (P ~ 0.9) and oscillations related to the functioning of the heart those in worker bees by a factor of 2.6 (P ≥ 0.99). An (ECG) in insects varies over a wide range depending on increase in temperature from the lower to upper limit of their physiological state and ecological situation its optimum range stimulates an increase in the ECG (Irishawa et al., 1956; Tyshchenko, 1976; Es’kov and amplitude in queens 1.3-fold (P > 0.95) and in worker Dolgov, 1986). In wasps and bumblebees, speciﬁc bees and drones 1.1-fold (P ~ 0.9). This is accompanied changes of ECG were observed under hypo- and hyper- by a 1.3-fold increase in
