Mitochondrial DNA variation in Spanish populations of Ceratitis capitata (Wiedemann) (Tephritidae) and the colonization process
Journal of Applied Entomology 128 (5), 358-364
Abstract: Mitochondrial DNA variation in the Mediterranean fruit fly Ceratitis capitata (Wiedemann, Diptera: Tephritidae) was studied in three natural populations from southern, central and eastern Spain by means of restriction fragment length polymorphisms using 22 restriction endonucleases. Nine different haplotypes were found based upon the restriction patterns of the seven polymorphic endonucleases, providing a measure of discrimination between populations (NST = 0.2462, FST = 0.154). The observed distribution of haplotypes, corroborated by a parsimonious unrooted tree, suggests an ancient origin for haplotype VII, and a first step in the colonization of the Iberian Peninsula and subsequently the northern and eastern Mediterranean basin, through the Straits of Gibraltar. No relationship can be established between the colonization process for Europe and America.
