Our findings show that in mainland Greece between 21-24 longitude E M josephi is absent from both brutia pine and Aleppo pine. The absence of M Joseph from brutia pine in Chalkidiki and the island of Thasos raises the possibility that the tree has been introduced by man without the scale insect the introduction by seed from Asia Minor could have been made for the production of honeydew by Marchalina helleni-ca Gennadius Homoptera Margarodidae whose excretions are the main source of honey in those areas. The occurrence of M josephi in Turkey and Crete and its absence from Aleppo pine in mainland Greece tend to confirm that brutia pine is the principal host of the scale. Brutia pine and M Joseph could have migrated together via the remnants of the land bridge connecting southeast Anatolia to Crete some 4-5 million years ago.
