Аннотация:Vibrations induced in plant stems by wind and mechanical activity of insects are investigated. The most of the energy of vibrations is concentrated in the range up to 1 kHz, usually additional peak at the frequencies from 2 to 4 kHz presents in the frequency spectrum. If the amplitude of vibrations is rather low, vibratory signals of Homoptera (Cicadinea and Psyllinea) can be distinguished against background noises. When the wind velocity is high, noises can jam the signal and communication became impossible. Possible ways to avoid wind-induced noises are discussed. It is demonstrated, that in certain cases insects do not sing if the amplitude of noises is high, but produce their signals only during the periods of lull between the wind rushes.
