Abstract：The chromosomal karyotype of early embryos of Tetramorium caespitum(L.) was studied by hypotonic treatment and drying in Shangqiu. The results showed that Tetramorium haploid chromosome number is 22 (n=22), and its diploid chromosome number is 44 (2n=44). Its karyotye consists of 10 pairs of metacentric chromosomes, 3 pairs of submetacentric chromosomes and 9 pairs of subtelocemtric chromosomes.
