Average number of homotypic and heterotypic matings recorded in mating compatibility studies in walk-in field cages using wild <i>Bactrocera oleae</i> populations from Croatia (Cro), France (Fr), Italy (It), and Spain (Sp), and a laboratory hybrid strain from Israel/Greece (Is/Gr).

The letter A indicates origin of first B. oleae strain and B indicates origin of second B. oleae strain. For the mating pairs, the first letter indicates the male insect and second letter indicates the female insect. The average numbers of replicated mating values of each combination are presented (8 replicate/combination).
