Vibro-Acoustical Signals of the Locust Trilophidia annulata (Thunb.) (Orthoptera; Acrididae, Oedipodinae)

摘要

Vibrational and acoustical signals of Trilophidia annulata (Thunb.) are described for the first time. Oscillogramms are presented.The genus Trilophidia Stal, 1873, belongs to the tribe Trilophidiini Shumakov, 1963, out of the subfamily Oedipodinae (Acrididae). Currently, it comprises ten species. T. annulata (Thunberg, 1815) is the only species that occurs on the territory of Primorskii krai, Russia (Fig. 1). It is widespread in Japan, Southeastern Asia, Korea, China, Sri Lanka, India, and Pakistan.No previous study has investigated the acoustical communication and signals of Trilophidia spp.
