Marchalina hellenica
''Marchalina hellenica'' is a scale insect that lives in the eastern Mediterranean region, mainly in Greece and Turkey. It is the sole member of the genus ''Marchalina''. It lives by sucking the sap of pine trees, mainly the Turkish Pine (''Pinus brutia'') and, to smaller extent, Aleppo Pine (''Pinus halepensis''), Scots Pine (''Pinus sylvestris'') and Stone Pine (''Pinus pinea''). It can be found in the cracks and under the scales of the bark of these trees, hidden under the white cotton-like wax it secretes. Its main form of reproduction is parthenogenesis.
The honeydew it produces is an important source of food for forest honey bees, which produce pine honey. In Greece and Turkey, about 60% of the honey production is derived from it. All over Greece the large scale artificial infestation of pine trees with ''Marchalina hellenica'' by bee keepers has resulted in the loss of the ecological balance between the insect and its natural predators; as a result trees in the surrounding pine forests are overburdened by the insect and dying.
In 2006 ''Marchalina hellenica'' was included in the European and Mediterranean Plant Protection alert list.
