Infestations by RPW
in Italy seem to have original from imported palms (plants with gread
development) without an appropriate inspection neither phytosanitary
control. Although it is difficult to specify their origin and date, it seems
that the introduction was carries out at 2003; during this year several
palms have been imported from Egypt or North Africa.
In Sicily the RPW attacks only plants of
which are higher than 5 m height grown in various town gardens.
Many male Canarian palms were dead in Catania province
(Acireale, Acicastello, Trecastagni, S. G. La Punta).
No attacks of this pest were detected on
Phoenix dactylifera and
others ornamental palms in Sicily and in Italy (Tuscany and Campany).
In Sicily, the elimination of infested trees has not been
applied systematically as soon as the pest was detected.
The work carried out, from the RPW
identification, according to the European Union legislation, these have had
as objective to eradicate to the pest. In the Work
Group “ Emergenz Punteruolo rosso delle palme” are interested:
Proff. Santi Longo and Giancarlo Polizzi (Università di
Catania - Dipartimento di Scienze e Tecnologie Fitosanitarie). Prof. Daniela
Romano (Università di Catania, Dofata);
Dr. Filadelfo Conti, Ernesto Raciti, Valentina Tamburino,
Franca Sesto (Regione Siciliana. Servizio Fitosanitario Regionale.
Unità Operativa 54, Acireale, Catania)
All the works have carried out in
coordinated form, by means of periodic meeting.
A) The prof. Longo has developed the following lines:
1) Morphology of RPW.
The adults (45 males and 37 females) collected in Sicily
(Acireale, Acicastello, Marina di Ragusa) during 2005.06, varies in size and
is 31,12 mm (30,94 males, 32,13 female) in length and 10,14 mm (10,06 males,
10,33 females) in width. The head and rostrum comprise is 9,24 mm (8,61
males, 9,87 females).
Prothoracic spots position of Rhynchophorus
ferrugineus adults collected in Sicily:
2) Natural enemies of RPW.
Ectoparasitic mites were found at mesothoracic wing,
under the elytra on mesotoracic targets of RPW adults.
The natural pathogens (fungi and bacteria) of RPW in its
habitat in infested palms caused high mortality rates of larvae and pupae.
3) Valuation effectiveness, in olfactomer, under
laboratory conditions of Tripheron Pheromone and System of trap (Tripheron
Pheromone trap) in public parks and private gardens in Catania and
Acicastello for effectively mass trapping RPW or monitoring its flights.
B) The Dr. Conti, Raciti, Sesto and Tamburino, in
December 2005- February 2006, has esamined 492 palm trees in Acireale,
Acicastello, S. G.la Punta and Trecastagni, 56 of them are infested of RPW
(infestation rate 11,4%).
