Abstract : Studies were carried out on the relative abundance of Dacus zonatus [Bactrocera zonata] and D. dorsalis [B. dorsalis] in 6 varieties of mango. The pupal recovery and pupal survival from 1 kg of infested fruit showed that cvs Sonehra and Beganpali were preferred over cvs Sindhri, Desi, Almas and Langra. While numbers of B. zonatus were higher than those of B. dorsalis in all varieties, relative preference of both species was very similar. Trap catches in mango orchards in Pakistan also showed a dominance of B. zonatus over B. dorsalis. Adult fly populations were at their peak during fruit maturation in June.
