Bioacoustics of Neoaliturus argillaceus

Hosts. Collected from Artemisia arenaria in Saratov Oblast , from ruderal vegetation with Artemisia sp. on roadside in Rostov Oblast , and from A. glauca in Southern Tyva , Southern Siberia. Calling signal. Signals of males from the following localities were investigated. 1. North Caucasus , Chechnya , Terskiy Mtn. Range in the environs of Grozny City , 4 and 7. VII. 1986 , signals of four males were recorded at 22 and 28 oC . 2. Rostov Oblast , Oblivskiy Region , environs of Sosnovy (=Oporny) Village on the Chir River , 17. VIII. 1992 , signals of one male were recorded at 28–30 oC . 3. Saratov Oblast , Krasnokutskiy Region , Dyakovka Village , 10. VII. 2004 , signals of one male were recorded at 27 oC . 4. Southern Siberia , Southern Tyva , environs of Erzin Village , 11. VIII. 1989 , signals of one male were recorded at 27 oC . The calling signal is a phrase consisting of syllables following each other with a period of about 0.5– 1.5 s ( Figs. 187–189 ). Each syllable consists of a short monotonous fragment with almost indistinguishable pulses followed by two short discrete pulses ( Figs. 190–192 ); quite often these pulses have much lower amplitude than a monotonous fragment ( Fig. 190 ). Sometimes, in the first half of a phrase continuous train of low-amplitude pulses presents ( Fig. 187 ).
