| Abstract: | First results on releasing experiments of Ageniaspis citricola Logvinovskaya (Hym., Encyrtidae), a parasitoid of Phyllocnistis citrella Stainton (Lep., Gracillariidae) in Tunisia . Trials were conducted to reduce the population of the citrus leafminer Phyllocnistis citrella in Citrus orchards by releasing the imported specific parasitoid Ageniaspis citricola in Tunisia. Adults of the parasitoid were released in 69 orchards between 1 June and 23 December 1996, corresponding to the two main flushes of Citrus . Results indicate that the parasitoid was established in 27 orchards reaching a maximum percentage of parasitism of 28%. In 1997, A. citricola is established in some Citrus groves proving its real acclimatization in Tunisia, with a maximum percentage of parasitism reaching 45%. |
