Abstract
From December 1997 to March 1999 samples of leaves infested by
Citrus Leaf Miner Phyllocnistis citrella (CLM)_Stainton were collected in several
citrus groves around Palermo in arder to bred indigenous parasitoids. Among the
different species of Eulophid wasps emerged also: Asecodes delucchii (Boucek),
Baryscapus sp., Elasmus sp., Aprostocetus sp.. This latter species was also
obtained by Stigmella sp. on Ulmus sp .. In Italy these parasitoids were not known
to attack the already mentioned Gracillariid. Among those already known all
developmental stages of Semielacher petiolatus (Girault) were observed during
winter 1998-1999. These records highlight a probable permanent establishment
of this parasitoid in the Sicilian citrus groves. With the aim of strengthening the
natural biological control against the CLM, a strain of Citrostichus
phyllocnistoides (Narayanan) introduced from Jordan is now bred in arder to
support its releases into citrus groves of the Island.
