摘　　要：选取幼虫或蛹的脑神经节,通过低渗、固定处理,然后镜检分析,对采自桂林市郊的4种蚂蚁,即粗纹举腹蚁C rem a tog aster artif ex M eyr、伊大头蚁P heid ole yeensis Fore l、印度大头蚁P heid ole ind ica M ayr、平和弓背蚁C amp onotus m itis(F.Sm ith)进行了核型分析.结果表明:粗纹举腹蚁2n=34、伊大头蚁2n=18、印度大头蚁2n=18、平和弓背蚁2n=28;除伊大头蚁的第1条染色体及印度大头蚁的第12条染色体分组为sm型外,其余染色体及另2种的所有染色体分组均为m型.On the basis of Chromosome making, the paper makes primary karyotype analysis for 4 species, belonging to 4 genera,in Formicidae, which collected around suburb of Guilin city. They are Crernatogaster artifex Meyr,Pheidole yeensis Forel,Pheidole indica Mayr and Carnponotus rnitis （F. Smith）. Their 2n numbers are as follows. Crernatogaster artifeac Meyr 2n = 34, Pheidole yeensis Forel 2n = 18, Pheidole indica Mayr 2n= 18,Camponotus mitis （F. Smith）2n = 28. Meanwhile,the paper finds out that almost all chromosomes are m type except the first chromosome of Pheidole yeensis Forel,the twelfth chromosome of Pheidole indica Mayr is sm type with strict correlative statistic.
