THE POSSIBILITY TO USE COMPUTER ANALYSIS FOR TWILIGHT ACOUSTIC BACKGROUND IN INSECTS OF THE COMMUNITY ORTHOPTERA (TETTIGONIIDAE, GRYLLIDAE) FROM THE EXAMPLE OF AN AGROCENOSIS IN EASTERN BULGARIA

摘要

A computer analysis of records of the twilight acoustic background in grasshoppers (Tettigoniidae) and crickets (Gryllidae) was performed in an agrocenosis of eastern Bulgaria. Seven species were identified according to the dynamic spectrograms. The analysis of the stridulation spectrograms of Ensifera is shown to allow solving both environmental and faunal problems and investigating the acoustic interactions of conspecific and heterospecific species in the same biotope.
