Karyotype of the Horn Fly, Haematobia irritans(L.)(Diptera, Muscidae).
The karyotype of Haematobia irritans is reported along with data on nucleolar organizer regions (NORs). The karyotype (2n=10) is characterized by the presence of 3 metacentric and 2 submetacentric pairs and the absence of heteromorphic chromosomes. One of the submetacentric pairs seems to present a pericentromeric NOR.
