Abstract:	The occurrence of the copia transposable element in 18 species of the repleta group of Drosophila has been studied using the Southern technique. The homologous sequence of copia was detected, either with radioactive or non-radioactive nucleic acid detection systems, as a pattern of multiple bands in species of the mercatorum and mulleri subgroups. Nevertheless, this sequence was not detected in the hydei subgroup. The intraspecific polymorphism in the pattern of bands indicates that this sequence is likely to be mobile. Some of the results could suggest the existence of restriction polymorphism of the copia homologous sequence in D koepferae populations. The partial sequencing of two independent clones isolated from D buzzatii clearly establishes that these elements are related and are likely to be the same.
