The ongoing naturalisation of Eucalyptus spp. in the Mediterranean Basin: new threats to native species and habitats

2019

The genus Eucalyptus has been widely introduced into many regions of the world outside its native range and has become invasive in some Mediterranean biomes (e.g. in southern Africa and California). In the Mediterranean Basin and Europe, eucalypts were introduced at the end of the 18th century. However, natural regeneration events in these regions are recent in time and limited in terms of affected areas, except for the Iberian Peninsula. An updated overview about the natural spread of Eucalyptus species in Italy is still lacking. This paper aims to fill this knowledge gap, using both published data and unpublished field data regarding naturalisation events, with a specific focus on Sicily.…

Modeling Environmental Influences in the Psyllaephagus bliteus (Hymenoptera: Encyrtidae)-Glycaspis brimblecombei (Hemiptera: Aphalaridae) Parasitoid-…

2017

Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae) is an invasive psyllid introduced into the Mediterranean area, where it affects several species of Eucalyptus. Psyllaephagus bliteus Riek (Hymenoptera: Encyrtidae) is a specialized parasitoid of this psyllid that was accidentally introduced into Italy in 2011. We developed a model of this host–parasitoid system that accounts for the influence of environmental conditions on the G. brimblecombei population dynamics and P. bliteus parasitism rates in the natural ecosystem. The Lotka–Volterra-based model predicts non-constant host growth and parasitoid mortality rates in association with variation in environmental conditions. The model was …

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

2011

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 Ame…
