摘要: 本文首次报道中国螽斯科3种昆虫的染色体核型,结果表明:中华螽斯Tettigonia chinensis 2n♂=31均为近端着丝粒染色体,暗褐蝈螽Gampsocleis obscura 2n♂=31也均为近端着丝粒染色体,中华寰螽Atlanticus sinensis 2n♂=29第1对染色体为中部着丝粒染色体,其余为近端部着丝粒染色体。这3 种螽斯的性别决定机制均为XO♂/XX♀型。
Abstract:The karyotypes of three species belonging to three genera of Tettigoniidae were investigated.The diploid number of chromosomes for Tettigonia chinensis is 2n♂=31,for Gampsocleis obscura 2n♂=31,Atlanticus sinensis 2n♂=29.In the three species,the XO♂/XX♀type of sex determination was observed.
