Between 1988 and 1989, M. lounsburyi from France was introduced into Cyprus (Orphanides 1993). A total of 81,000 individuals were released (Orphanides 1993). The species turned out to be very efficient; due to the combined effect of M. lounsburyi and M. helvolus (Section 1.50.6), S. oleae population densities reduced from outbreak level to almost non-existence and remained at low levels after the discontinuation of these releases (Orphanides 1993).
