ABSTRACT. This article examines some of the most significant advances in insect bioacoustics in the first quarter of the 21st century, covering vibroacoustic signaling, ecological aspects of acoustic communication (ecoacoustics), and the processing of vibroacoustic information in the mechanosensory system, including mechanisms for recognizing sound signals. Breakthroughs in some areas of bioacoustics have been made possible by the modernization of traditional and the development of new research methods (immunohistochemistry, calcium imaging, microtomography, optogenetics, connectomics, etc.). New information has been obtained on the sound signaling of a vast number of insect species, and representative insect sound libraries, primarily from Orthoptera and Hemiptera, have been compiled. The features of mechanoelectrical transduction in insect auditory receptors are revealed, the structures and mechanisms that enhance sensitivity to sound, nonlinearities in the functioning of receptors and auditory interneurons are identified, and existing hypotheses for the recognition of species-specific sound signals are considered. Within the new field of ecoacoustics, studies have been conducted on acoustic niches, the propagation characteristics of acoustic signals in transmission channel, and the soundscape of biocenoses. The most promising research directions for the coming years have been identified.
KEY WORDS: insects, acoustic signaling, ecoacoustics, hearing, acoustic signals recognition.
