Karyotypes of eleven parasitoid species of the family Eulophidae were examined, namely, Chrysocharis laomedon (Walker, 1839) (2n = 10), Chrysocharis sp. aff. laomedon (n = 5, 2n = 10), Chrysocharis sp. aff. albipes (Ashmead, 1904) (2n = 12), Mischotetrastichus petiolatus (Erdös, 1961) (n = 6, 2n = 12), Minotetrastichus frontalis (Nees, 1834) (n = 5, 2n = 10), Cirrospilus pictus (Nees, 1834) (2n = 12), Hyssopus geniculatus (Hartig, 1838) (2n = 16), Sympiesis gordius (Walker, 1839) (2n = 12), S. sericeicornis (Nees, 1834) (2n = 12), Pnigalio agraules (Walker, 1839) (2n = 12 + 0-2B) and Pnigalio gyamiensis Myartseva & Kurashev, 1990 (2n = 12 + 0-6B) reared from Phyllonorycter acerifoliella (Zeller, 1839), Ph. apparella (Herrich-Schäffer, 1855), Ph. issikii (Kumata, 1963) (Gracillariidae) and Chrysoesthia sexguttella (Thunberg, 1794) (Gelechiidae). Chromosome sets of all species except P. agraules and P. gyamiensis were studied for the first time. B chromosomes were detected in the two latter species; in P. gyamiensis, the maximum number of B chromosomes represents the highest value known for parasitic wasps to date.
对姬小蜂科11种寄生蜂的核型进行了研究，即：黄斑金小蜂（Chrysocharis laomedon (Walker, 1839)）（2n = 10）、近似黄斑金小蜂（Chrysocharis sp. aff. laomedon）（n = 5，2n = 10）、近似白足金小蜂（Chrysocharis sp. aff. albipes (Ashmead, 1904)）（2n = 12）、柄瘤四节小蜂（Mischotetrastichus petiolatus (Erdös, 1961)）（n = 6，2n = 12）、额角小蜂（Minotetrastichus frontalis (Nees, 1834)）（n = 5，2n = 10）、斑痣悬茧姬小蜂（Cirrospilus pictus (Nees, 1834)）（2n = 12）、膝曲长腹姬小蜂（Hyssopus geniculatus (Hartig, 1838)）（2n = 16）、食蚜金小蜂（Sympiesis gordius (Walker, 1839)）（2n = 12）、丝角食蚜金小蜂（S. sericeicornis (Nees, 1834)）（2n = 12）、黄腹柄翅小蜂（Pnigalio agraules (Walker, 1839)）（2n = 12 + 0 - 2B）和加氏柄翅小蜂（Pnigalio gyamiensis Myartseva & Kurashev, 1990）（2n = 12 + 0 - 6B），这些寄生蜂分别采自械叶潜蛾（Phyllonorycter acerifoliella (Zeller, 1839)））、似械叶潜蛾（Ph. apparella (Herrich-Schäffer, 1855)）、石垣潜蛾（Ph. issikii (Kumata, 1963)）（细蛾科）和六斑绢野螟（Chrysoesthia sexguttella (Thunberg, 1794)）（麦蛾科）。除黄腹柄翅小蜂和加氏柄翅小蜂外，所有物种的染色体组均为首次研究。在这两个物种中检测到了B染色体；在加氏柄翅小蜂中，B染色体的最大数量代表了迄今为止已知寄生蜂的最高值。
