ual search of specimens or by examination of
symptoms. Species identification was based
on the morphology of adults and preimagi-
nal stages; important was the observation of
the type of galls and leafmines and the asso-
ciation with the host plants. Part of the sam-
ples was conserved in 75% ethanol and la-
belled. The collected material was studied
in the laboratory, dissected under a binoc-
ular microscope and prepared when neces-
sary. Examined material is preserved in the
private collection of the author and partly in
the entomological collection of the Depart-
ment of Agri-food and Environmental Sys-
tems Management, University of Catania.
Results
Detected species
Hemiptera, Psyllidae
Acizzia jamatonica (Kuwayama 1908)
Native range: species of oriental origin (Chi-
na, Korea and Japan).
Distribution: in Europe, it was first detect-
ed in Italy and later recorded in numerous
European countries, including the Unit-
ed Kingdom, Portugal, Spain, France, Corsi-
ca, Switzerland, Germany, Slovenia, Croatia,
Montenegro, Serbia, Slovakia, Greece, Bul-
garia and Hungary. Since 2006, it has been
found in the United States of America (Bel-
la, 2013).
Host plant: different species of
Albizia
(Fa-
baceae, Mimosoideae); in Europe on the Per-
sian silk tree,
A. julibrissin
(Willdenow) Du-
razzini.
Material examined: Corfu city, 39°37΄N,
19°55΄E, 10 m a.s.l., 17.VIII.2013, adults on
A.
julibrissin.
Biological remarks: the life cycle of
A. jama-
tonica
includes numerous overlapping gen-
erations; the psyllid overwinters in the adult
stage. Leaves and shoots can be completely
colonised by juvenile and adult stages with
serious damage, leading to total or partial
desiccation. Large amounts of honeydew
are produced and can cause some incon-
venience in urban environments (Sánchez
García and Burckhardt, 2009).
Glycaspis brimblecombei Moore 1964
Native range: species described from Aus-
tralia.
Distribution: this species has shown inva-
sive behaviour in the last 15 years and has
spread across several continents outside
its native range. It was first detected in the
United States of America (California, Florida
and the Hawaiian Islands) and subsequent-
ly recorded from Mexico, Central and South
America (Brazil, Uruguay, Ecuador, Venezue-
la, Colombia, Peru, Chile and Argentina) and
Africa (Morocco, Algeria, Tunisia and South
Africa). It is also found in the Canary Islands,
New Zealand and Mauritius (Bella, 2013). In
Europe,
G. brimblecombei
is reported from
Portugal, Spain, France, Corsica, Italy, Sici-
ly, Sardinia, Greece, Corfu and Montenegro
(Bella and Rapisarda, 2013; Reguia and Peris-
Felipo, 2013; Ben Attia and Rapisarda, 2014;
Milonas and Partsinevelos, 2014; Tsagkarakis
et al.
, 2014).
Host plant: associated with different species
of Eucalyptus (Myrtaceae) (Brennan
et al.
,
2001); in the Mediterranean area mainly on
the River red gum,
E. camaldulensis
Dehnh.
Material examined: 16-20 August 2013; Ben-
itses, 39° 32΄N, 19° 54΄E, 6 m a.s.l.; Lefkim-
mi 39° 24΄N, 20° 04΄E, 6 m a.s.l.; Kassiopi,
39° 47΄N, 19° 45΄E, 8 m a.s.l.; Corfu city, 39°
37΄N, 19° 55΄E, 10 m a.s.l.; Roda, 39° 47΄N, 19°
48΄E, 27 m a.s.l.; Agios Mattheos, 39° 29΄N,
19° 52΄E, 140 m a.s.l.; Sinarades, 39° 34΄N, 19°
50΄E, 151 m a.s.l.; Kato Garouna, 39° 32΄N, 19°
51΄E, 225 m a.s.l.; Pelekas, 39° 35΄N, 19° 49΄E,
247 m a.s.l.; nymphal stage and adults have
been observed on
E. camaldulensis
.
Biological remarks: nymph instars construct
white conical lerps using wax and honey-
dew secretions, while the adults are highly
mobile and live freely on the foliage. It pro-
duces copious amounts of wax and honey-
dew on the infested leaves, causing desicca-
tion and premature leaf drop (Laudonia and
Garonna, 2010).
