Abstract A wide spectrum of repetitive DNA amounts and interspersion patterns is seen in mosquitoes and other dipterans. Using a simple and rapid technique, we show that these range from a minimal amount in five species of Anopheles through moderate amounts in Culex quinquefasciatus to large amounts in Aedes aegypti and Stomoxys calcitrans. Although Culex and Aedes are closely related and both have a considerable amount of interspersed repetitive DNA, the repetitive sequences are different between the two genera. These results and previously published information show that the amount of repetitive DNA and sequences involved have changed many times during the evolution of the Diptera.
