PRESENZA IN SICILIA DI GLYCASPIS BRIMBLECOMBEI MOORE (Hemiptera Psyllidae) SU EUCALYPTUS CAMALDULENSIS DEHNH..

On the presence in Sicily of Glycaspis brimblecombei Moore (Hemiptera Psyllidae) on Eucalyptus camaldulensis Dehnh. Authors record the occurrence in Sicily of the red gum lerp psyllid, Glycaspis brimblecombei Moore (Hemiptera Psyllidae) attacking Eucalyptus camaldulensis Dehnh. (Myrtaceae). This species, native to Australia, has been first reported for the Palaearctic Region in 2008, when it has been recorded from the Iberian Peninsula. In 2010 it has been found also in Italy. It seems very difficult to control this insect without the diffusion of its specific antagonist Psyllaephagus bliteus Riek (Hymenoptera Encyrtidae), which resulted very effective in its biological control in North America.
