Marchalina hellenica is the main honeydew producing insect of pine trees. It is endemic to Greece and Turkey and introduced to the Italian island of Ischia. It has one generation per year and the adult females appear on the trees only after mid March. Studies on the genetic structure of the insect show that the low genetic variability may be due to the fact that it can not be dispersed long distances in correlation with the parthenogenetic reproduction. The amount of honeydew produced by the insect varies over the year and mainly depends on the size and age of the nymphs. [ABSTRACT FROM AUTHOR]

The first samples of recently produced fir honeydew honey, obtained from Marchalina hellenica (Gennadius) (Homoptera, coccoidea, Margarodidae), originating from Mount Helmos in Greece were analysed and examined on the basis of physical and chemical parameters including humidity, acidity, sugar profile, hydroxymethylfurfural (HMF) and diastase activity. These data were compared with five other Mediterranean honeydew honeys of different origin obtained from the literature. Analytical data of the Greek fir honey from M. hellenica honeydew complied with the E.U. legal limits. The sensorial analysis indicated that the organoleptic characteristics of this type of honeydew honey were very similar to the Greek fir honey derived from other coccids with respect to colour, taste and smell. The statistical analysis of the physico-chemical parameters of the six honey types revealed two major groups. One group consisted of three Greek honeys and the other included one Spanish and two Italian honeys. it also showed a marked similarity between the two Greek honeys that came from M. hellenica honeydew on either fir or pine trees.
