First results on releasing experiments of Ageniaspis citricola Logvinovskaya (Hym., Encyrtidae), a parasitoid of Phyllocinistis citrella Stainton (Lep., Gracillariidae) in Tunisia.

Trials were conducted to reduce the population of the citrus leafminer Phyl locnistis citrella in Citrus orchards by releasing the imported specific pa rasitoid Ageniaspis citricola in Tunisia. Adults of the parasitoid were rel eased in 69 orchards between 1 June and 23 December 1966, corresponding to the two main flushes of Citrus. Results indicate that the parasitoid was es tablished in 27 orchards reaching a maximum percentage of parasitism of 28% . In 1997, A. citricola is established in some Citrus groves proving its re al acclimatization in Tunisia, with a maximum percentage of parasitism reac hing 45%.
