First record in Algeria of two eulophid wasps: Closterocerus chamaeleon (Girault) and its host, the eucalyptus gall wasp Ophelimus maskelli (Asmead) (Hymenoptera Eulophidae).

摘要

The endophagous parasitoid Closterocerus chamaeleon, released in Israel, Italy and Corsica, for classical biological control programs, and its host, the gall-maker Ophelimus maskelli, were recorded for the first time in Algeria, in a straight line 450 km far from the Sardinian release site and 700 km far from the closest Sicilian release site. Their presence is confirmed in Andalucia (Spain), about 2000 km far from release sites of Sicily and Campania. In about two years the parasitoid spread and was established in many Mediterranean countries.
