Predatory stinkbugs Picromerus bidens (Pentatomidae: Asopinae) produce communication vibratory signals by abdomen vibration and tremulation. As first in Asopinae we described the female song. Abdomen vibration produced signals show frequency characteristics of the family Pentatomidae: the dominant frequency peak lies around 100 Hz and higher harmonic peaks do not exceed 600 Hz. Tremulatory signals are broad-banded with peaks up to 400 Hz. The rich song repertoire probably replaces the lack of the aggregation pheromone characteristic for some other asopine species with less types of signals.

The authors described in their contribution the insect mechanical and chemical signals which may be used in the frame of the insect pest biological control either as pheromone traps or as the source of disturbances which decreases effective communication in the field. Insect chemical and mechanical communication signals are species specific and are as such most convenient for the use in biological pest control as they affect just the target species.
