五种蟋蟀染色体的研究 A Study on Chromosomes in Five Crickets

报道了中国4种蟋蟀的染色体C带核型，即黑脸油葫芦 Teleogryllus occipitalis (Serville,1838)，2n=27,XO(♂)；银川油葫芦 T.infernalis (Saussure,1877)，2n=27,XO(♂)；迷卡斗蟋 Velarifictorus micado (Saussure,1877)，2n=29,XO(♂)；泰康棺头蟋 Loxoblemmus taicoun (Saussure,1877)，2n=17,XO(♂)及长颚斗蟋V.aspersus (Walker,1869)的核型即2n=23,XO(♂)。4种蟋蟀各染色体均显示强的着丝粒带，多数染色体显强或中的端带，斗蟋属(Velarifictorus)1种部分染色体显示居间带，油葫芦属(Teleogryllus)2种和棺头蟋属（Loxoblemmus）1种无居间带，各物种表现出明显的种类特异性。对蟋蟀染色体及C带核型在分类中的意义作了初步的探讨。 Abstract:This is a report on the chromosome C-banded karyotypes of four Gryllidae species in China.They are Teleogryllus occipitalis(Serville,1838),2n=27,XO(♂);T.infernalis(Saussure,1877),2n=27,XO(♂);Velarifictorus micado (Saussure,1877),2n=29,XO(♂);Loxoblemmus taicoun Saussure,1877,2n=17,XO(♂).And another karyotype is reported as well,it is V.aspersus（Walker,1869）,2n=23,XO(♂).All chromosomes of the four crickets show strong paracentric C-bands,lots of the arms show strong or median terminal C-bands,and some chromosomes of V.micado show middle C-bands.In addition,the total heterochromatin content of the four crickets was shown.The cytotaxonomic significance is discussed.

A Study on Chromosomes in Five Crickets

This is a report on the chromosome C-banded karyotypes of four Gryllidae species in China. They are Teleogryllus occipitalis(Serville,1838), 2n=27,XO(male symbol); T.infernalis(Saussure,1877), 2n=27, XO(male symbol);Velarifictorus micado (Saussure,1877), 2n=29, XO(male symbol);Loxoblemmus taicoun Saussure, 1877, 2n=17, XO(male symbol). And another karyotype is reported as well,it is V.aspersus(Walker,1869), 2n=23, XO(male symbol). All chromosomes of the four crickets show strong paracentric C-bands, lots of the arms show strong or median terminal C-bands,and some chromosomes of V.micado show middle C-bands. In addition,the total heterochromatin content of the four crickets was shown.The cytotaxonomic significance is discussed.
