As a part of ongoing cytogenetic studies on the jewel-beetles (Buprestidae, Coleoptera) of Armenia, the male karyotypes and meiosis of nine species (5 genera, 4 tribes, 2 subfamilies) are described, figured and discussed. In Ovalisia nadezhdae Sem., Sphenoptera artemisiae Reitt., Coraebus rubi L., C. sinuatus Creutz., Meliboeus caucasicus Reitt., Agrilus angustulus Ill. Men., A. obscuricollis Kiesw., and A. araxenus Khnz. diploid chromosome numbers vary in a narrow range from 20 to 24. In Sph. glabrata Men. a high chromosome number of 2n=40 was discovered. All the species have a XY sex chromosome system, which is however of different types. The data available on the buprestid karyotypes and karyotype variation at different taxonomic levels within the family are discussed.
作为对亚美尼亚吉丁虫（鞘翅目：吉丁甲科）进行的细胞遗传学研究的一部分，本文描述、绘制并讨论了9种吉丁虫（5属、4族、2亚科）的雄性核型和减数分裂情况。在纳氏卵形吉丁（Ovalisia nadezhdae Sem.）、蒿斯氏吉丁（Sphenoptera artemisiae Reitt.）、红胸吉丁（Coraebus rubi L.）、弯纹吉丁（C. sinuatus Creutz.）、高加索美吉丁（Meliboeus caucasicus Reitt.）、窄吉丁（Agrilus angustulus Ill. Men.）、暗颈吉丁（A. obscuricollis Kiesw.）和阿拉克西吉丁（A. araxenus Khnz.）中，二倍体染色体数目在20至24的狭窄范围内变化。在光滑吉丁（Sph. glabrata Men.）中发现了较高的染色体数目2n = 40。所有物种都具有XY性染色体系统，但属于不同类型。本文还讨论了关于吉丁甲科核型以及该科内不同分类水平上核型变异的现有数据。
