KEY WORDS: Homoptera, Auchenorrhyncha, vibrational signals, signal transmission, communication channels, acoustic isolation.

ABSTRACT. It has been found experimentally that under natural conditions in the communities of herbaceous plants transmission of substrate-borne vibrational signals of small Auchenorrhyncha from stem to stem is possible both via the stems or leaves and via the roots. As a result, individuals occurring on different plants can perceive the signals of each other. Consequently, in sympatric species of grass-dwelling Auchenorrhyncha differences in host specialization by no means always provide segregation of vibratory communication channels.
