ABSTRACT

On June 2012, the ash Siphoninus phillyreae (Haliday) (: Aleyrodidae) was recorded for the first time on pomegranate in Greece. Its occurrence was observed in a pomegranate orchard at Kato , in Fthiotida. Information on its morphology, biology and distribution is presented.

KEY WORDS: Aleyrodidae, , first record.

Pomegranate is one of the oldest fruit (Coleoptera: Buprestidae) and the woolly species cultivated in Greece, known since whitefly, Aleurothrixus floccosus the prehistoric years. The main cultivation (Hemiprera: Aleyrodidae) (Drogoudi et al. places were mainly the Aegean islands 2012). (, Lesvos, , Rhodos, Kalymnos, The aim of the present study was to ), Crete, Peloponnese (Argos, Astros), report the first record of the ash whitefly, (Lamia) and Siphoninus phillyreae (Haliday) (Hemiptera: (Veria, Edessa, ) (Pontikis 1987). After Aleyrodidae) on pomegranate in Greece. 2007, cultivation was expanded in new areas The infested pomegranate trees (cv.

ΠΕΡΙΛΗΨΗ

Στην παρούσα εργασία γίνεται η πρώτη καταγραφή του είδους Siphoninus phillyreae (Haliday) (Hemiptera: Aleyrodidae) επί της ροδιάς στην Ελλάδα. Η παρουσία του είδους αυτού διαπιστώθηκε από δειγματοληψία που πραγματοποιήθηκε τον Ιούνιο του 2012 σε οπωρώνα με ροδιές στην Κάτω Τιθορέα Φθιώτιδας. Δίδονται πληροφορίες σχετικά με τα μορφολογικά και βιολογικά χαρακτηριστικά, όπως και για την εξάπλωση του εντόμου.
