title: Metaphase chromosomes of Culicoides variipennis Diptera:Ceratopogonidae).
abstract: The cytogenetics of Culicoides variipennis (Coquillett) tissue derived from a continuous cell line is presented. The karyotype consisted of 68.5% diploid (2n = 6), 30% tetraploid (4n = 12), and 1.5% octaploid (8n = 24) for the metaphase spreads examined. Distinguishing cytological features were not seen, and the 3 pairs of homomorphic chromosomes were not distinguished from each other.
