Özet:

Aim of study: To investigate the distribution area, some biological characteristics and host plant relationship of Spanioneura fonscolombii Förster (Hemiptera: Psylloidea) species, a psyllid we recently found its distribution in Turkey, for the first time within this study. Material and methods: We collected adults and nymphs of the insect from the host plants during the visits to the study area on different dates. The insect was recognised as a psyllid species. Some adult samples were sent to the expert Dr. Burckhard for species identification. The psyllid damage on host plants of Buxus balearica was identified for the first time as a new host for Spanioneura fonscolombii. Main results: 1- We identified Spaineura fonscolombii species distribution in Turkey for the first time, 2- Population size was highly dense in the study area based on initial observation, 3- New host plant, Buxus balearica, for the pest species was identified for the first time, 4- Overwintering properties of the pest species was determined. Research highlihts: First record of the pest in Turkey. Determination of the most Southern and Eastern, probably so far known, distribution of the pest species in the world. Determination of a new host plant for the pest.
