Abstract
Collections of Ceratitis capitata from 6 different areas from 4 Medite rranean countries were analysed for genetic variation. Six out of the 25 loci tested were found to be polymorphic. Allelic frequencies were estimated and the populations were found to be panmictic for 4 out of those 6 loci. Two of the polymorphic loci showed a significant clinal pattern in gene frequency changes by Spearman rank correlation with la titude. At 4 loci, a steep gradient in allele frequency (in Idh from 1 .00 to 0.63) is observed in the axis of the north-south transect.
