Modification of a new method for detecting changes in the activities of neuronal population and the nearest neuron is described. Preliminary measurements of the influence of a static magnetic field (2 mT) on neuronal population activity on eight individuals of an endangered insect species Morimus funereus are included. Five minutes exposure produced both excitatory (5/8) and inhibitory (3/8) effect on the activity of neuronal population of M. funereus antennal lobe. However, when the reversibility of induced effects was quantitatively analyzed, our results showed that they were prevailingly irreversible: (7/8) for the population, (6/8) for the nearest neuron.

The Hungarian investigator Janos Frivaldszky published results of faunal studies on territories that included some parts of the present Republic of Serbia (Frivaldszky, 1877). This paper reported, among others things, the finding of the species Sympetrum depressiusculum (S?lys, 1841) at the Uljma local?ity in South Banat. It represents the first data indicating the presence of this species in Serbia. For unknown reasons, this paper was not cited by the majority of workers that performed odonatological investigations in this region. Until the present time, there were no confirmations of the presence of this species either in Banat or in Serbia. The risk of oblivion of the finding published by Frivaldszky was suspended by recent findings of this species.
