Abstract

[automatically translated] Ophelimus maskelli, eulofide gall Eucalyptus spp., Introduced in Italy in 2000, causing desiccation and early fall of leaves attached. In 2003 it was initiated by the Volcani Center (ARO, Israel) and CSIRO (Australia) a biological control program, introduced in 2005 in Israel the parasitoid eulofide Closterocerus chamaeleon (Girault). In spring 2006, the Israeli institution sent to the Department. SENFIMIZO Palermo leaves of Eucalyptus with thousands of galls parasitized by C. chamaeleon. After the necessary tests on the assessment of the ecological risk of the introduction, in the first half of May, the parasitoid was released in Sicily in five eucalitteti, in the provinces of Palermo (3 sites), Trapani and Caltanissetta. In December 2006, several leaves with parasitized galls collected in Palermo have been sent, the Dep. Of Plant (DPP protection) of the University of Sassari in Sardinia and at Dip. GESAF University of Reggio Calabria in Calabria, who introduced the parasitoid attection in the provinces of Cagliari and Crotone. Its spread was monitored periodically by taking leaves of E. camaldulensis with galls of O. maskelli in places more and more distant from the release site. In Sicily C. chamaeleon to five months from the introduction it was found 2 km away in 2008 from the point of release and, across the island, including circum islands, Tunisia, Algeria and Andalusia. In the latter year, the parasitoid was found widely present in Calabria and Sardinia. The adults of C. chamaeleon,
