Abstract
In this study, the presence of the scale insect Dynaspidiotus abieticola (Koroneos) (Hemiptera: Diaspididae) has been recorded in fir trees, Abies cephalonica Loudon (Pinaceae), on the Taygetus mountain (Peloponnese, South Greece). The biology of the scale insect was observed during a twelve month period, from February 2013 to January 2014. It was determined that the insect completed one generation. It overwintered as a reproductive adult female. The first ovipositions and hatching of crawlers were observed in early May, 2nd instar nymphs appeared at the beginning of August, male nymphs were seen in September and finally the first adult females at the beginning of October.
