China Grylloidea Insect Sound And Song Time-domain Characteristics

The paper studied the stridulatory organs of 77 species and analyzedthe time domain characters of songs of 22 species. The morphology of stridulatoryorgans were studied in the S-570 Hitachi scanning electron microscope, after thetegmina had been air-dried and coated with gold. The songs were recorded withSONY WM-QX 6l4 cassette recorder (frequency response 40─l0000Hz). Mostspecies were recorded in the field or houses at night. The time domain characters ofsongs were analyed with Japan signal processor 7Tl70904─S and with the computeracoustic analysis techniques. The conclusions were as follow:â‘  For the first time, the paper studied systematically the stridulatory organs ofcrickets from China, including the morphology of the files and the ultrastructure ofthe teeth with scanning electron microscope.â‘¡ The file teeth of crickets showed pronounced interspecific differences. Thepaper further confirmed that the file teeth are reliable taxonomic characters.â‘¢ The resonator of crickets showed obvious interfamilial and intergenericdifferences. Most interspecific differences showed in mirror size and dividing veinshape. For the first time the paper studied systematics of resonator in the stridulatoryorgan.â‘£ The stridulatory organ of crickets showed obious intergeneric differences. Thepaper systematically summaried the characters of stridulatory organs of most genera.⑤ The stridulatory organs of crickets showed interfamilial differences. Thepaper systematically summaried the characters of stridulatory organs of most families.â‘¥ In describing characters of stridulatory organs, the paper used some newcharacters and terminologies, such as angle, teeth shape, left/right-end shape of teeth,Cu₂-longitudinal vein, Cu₂-transverse vein etc. These charcters are important tosystematics.⑦ For the first time, the time domain spectrum of long time collecting sampleswere adopted to studying songs of crickets and added to new way of analysing songsof insects. In addition, the paPer studied 6 new species: Oecanthus zhengi, OecanthusyUnnanensis GryllOdes Iativenter GryllOdes nanningensis, Tarbinskiellus nlerivertexLoxobIemmus yaoshanensis.
