A Note on the Natural Relocation of Marchalina hellenica (Gennadius) from Pine to Fir Trees

Abstract

Marchalina hellenica (Gennadius) (Hemiptera: Margarodidae) is the most important honeydew producing insect in Greece. It was referred as monophagus, feeding exclusively on pine trees, until 1995 when it was successfully established on fir trees after artificial “inoculation” at Menalo and Helmos mountains. In this scientific note, the first record of natural relocation of M. hellenica from pine to fir trees is referred.
