Between 1988 and 1989, M. helvolus was introduced from France into Cyprus and mass reared; subsequently, 2800 individuals were released (Orphanides 1993). Due to the combined effect of M. helvolus and M. lounsburyi (Section 1.50.7), S. oleae population densities have reduced from outbreak levels to almost non-existence and have remained at these low levels (Orphanides 1993).
