Аннотация: BIOLOGY AND VIBRO–ACOUSTIC COMMUNICATION OF THE SHORT–WINGED RICE GRASSHOPPER PSEUDOXYA DIMINUTA (WALK.) (ORTHOPTERA: ACRIDIDAE:OXYINAE) IN AN INSECTARIUMThe only representative of the genus Pseudoxya Yin & Liu, 1987 – is the rice short-winged grasshopper is widespread in Southeast Asia. This is a small insect, 15-18 mm in length (males) and 20-25 mm (females), with shortened elytra and wings (Fig. 1, 1 and 4), it turned out to be unpretentious in the content. Several individuals were obtained in 2010 from Laos (Prov. Vientiane) and in 2014 from Vietnam (Prov. Quảng Bình).These insects have a diet with a preference for cereals. When maintaining in the cage, they were preferred with Lolium perenne L., Phleum pratense L., Triticum durum Desf., Festuca pratensis Huds., Poa pratensis L. and Dactylis glomerata L. And Elytrigia repens (L.) Nevski, Calamagrostis epigeios (L.) Roth, Echinochloa crus-galli (L.) P. Beauv., Setaria pumila (Poir.) Roem. & Schult., Poa annua L., Festuca rubra L., F. ovina L., Phalaroides arundinacea (L.) Rauschert, Carex pallescens L. were fair to eaten, and such cereals as Avena sativa L., Arrhenatherum elatius (L.) J. Presl & C. Presl, Calamagrostis arundinacea (L.) Roth and many wild cereals with shining or fragrant leaves were ignored. Of the dicotyledonous, a number of plants such as Geum urbanum L., Rubus idaeus L., Alchemilla vulgaris L., Lamium album L., Glechoma hederacea L. and Lactuca sativa L. were well eaten by grasshoppers, however, when feeding, they did not have mating, so they can only be given temporarily. Females laid theegg-pods (Fig. 1, 2 and 3) in loose soil on a cage, and with sufficient humidity, also in the thick of the stems of cereals and even in the specially touched leaves of the two-bottom. The development of eggs at +24..+26 °C lasted a little morethan 2 months, and larvae – from one and a half to 2 months, while females grow a little slower. In their development, insects pass 5 ages, the number of lines in males and females is the same. Imago live from about 2 to 3 months. We noticed any seasonal cyclicity when keeping in the cage, there was no range at all stages. 58Specific mixed sound-vibrational communication in the short-winged rice grasshopper Pseudoxya diminuta (Walker) is described. Receptive femalesproduce rather loud sound signals by spines of hind tibiae scratching against elytra and body and thereby attract males (Fig. 2, 1). Besides, other females are probably warned of occupancy of the territory (this is part of the function of calling signals). Vibrosignals are not noticed for females, and also no sound signals are known for males. Unlike females, males produce only vibrational signals at close distances in two different ways, alternating them during the emission of one phrase (Fig. 2, 2). At the beginning of phrase the contraction of thorax muscles transmits as a welldefined vibrosignal via middle limbs into the substrate. It is followed by a tremulation (largeamplitude trembling) of hind limbs in a horizontal plane, perpendicular to the body axis, also inducing specific vibrations. It is possible that such role of communication has been developed in this species due to fierce competition for communication channels in the multispecies communities of singing insects of South-East Asia.
