Abstract

In mixed populations of wild and males from T (Y;5) 1-61 white female pupa genetic sexing strain of Ceratitis capitata (Wiedemann), sterilized males of the genetic sexing strain expressed calling, lekking and mating compatibility with their wild counterparts. Nevertheless, their mating performance was most of time poor to very poor. For example, in a series of studies from June-October 1996, only 0- about N of expected matings (based on insect ratios) by genetic sexing sterilized males was recorded. Similar results were observed in the other years of this study. No substantial differences between gen. sex. male × wild female and wild male × wild female type copulations were detected in spatial distribution of couples in copula on the orange tree. Over 83% of both mating types were detected on the underside leaf surface.
