Distribution of the mariner element among Drosophilidae species is investigated using three different techniques (squash blots, Southern blots and PCR amplification). Results demonstrate the distribution of mariner is not uniform and does not follow the phylogeny of the host species. Analysis of geographical distributions of the element shows it is mainly present in Asia and Africa.

The Ztub\mariner sequence has 97% identity to Dmau\mariner and the mariner sequence from Dmau\mariner has 92% identity to Dtsa\mariner. D.tsacasi is more related to D.mauritiana than Z.tuberculatus so the presence of the mariner sequence in Zaprionus may result from horizontal transfer.
