Unfaithful medfly females: Impact on SIT?

Abstract

Full text: In the field, medfly females can copulate more than once. This behaviour may be critical for the application of SIT against medfly natural populations. Whether the frequency of remating is dependent on both ecological conditions and population density is under investigation. Moreover, the observation that, in wild populations, remating is accompanied by a strong paternity skew, led to the formulation of an hypothesis on the mechanisms that regulate the use of sperm from different males. The elucidation of these mechanisms has been undertaken in the laboratory, using fly strains with different internal molecular markers. This will allow the description of the most significant medfly sexual/population behaviours to consider for SIT planning. (author)
