Abstract Two major and three minor male specific serum proteins (MSSPs) have been identified in the Mediterranean fruit fly Ceratitis capitata . All five MSSPs accumulate in the haemolymph during the first 3 days of the adult development and represent more than 50% of the total haemolymph proteins in the adult males. All MSSPs are dimeric proteins consisting of two subunits with molecular weights between 13.5 and 14.5 kDa. MSSP-1, 3, 4 and 5 are homodimers while MSSP-2 is a heterodimer. The two major MSSPs (MSSP-1 and 5) have been isolated. Antisera against these two MSSPs cross-react partially with each other's antigens but did not give any reaction with haemolymph from adult females and third instar larvae.
