Türkiye’de yeni bir okaliptüs tohum gal arısı Quadrastichodella nova Girault, 1922 (Eulophidae: Tetrastichinae)

Bu çalışma, 2006 ve 2007 yıllarında Akdeniz Bölgesi’nde okaliptüs yetiştirilen alanlarda yürütülmüştür. Eucalyptus spp. tohum kapsüllerinde Quadrastichodella nova Girault (Hymenoptera: Eulophidae: Tetrastichinae) ülkemizde ilk defa elde edilmiştir. Tohumlar üzerinde gal oluşturan bu türün enfeksiyonunun düşük düzeyde olduğu görülmüştür. Eucalyptus camaldulensis L. (Myrtaceae) bitkisinın Q. nova için yeni bir konukçu olduğu saptanmıştır.Bu çalışma, 2006 ve 2007 yıllarında Akdeniz Bölgesi’nde okaliptüs yetiştirilen alanlarda yürütülmüştür.

First Record of the Eucalyptus Seed Gall Wasp, Quadrastichodella nova Girault, 1922, (Eulophidae: Tetrastichinae) from Turkey

The present study was carried out during 2006 and 2007 in a eucalyptus planted area in the Mediterranean region of Turkey. The eulophid species Quadrastichodella nova Girault (Hymenoptera: Eulophidae: Tetrastichinae) was collected on Eucalyptus spp. seed capsules for the first time in Turkey. This species induces galls on the seeds, attaining low levels of infestation. The plant species Eucalyptus camaldulensis L. (Myrtaceae) is reported as new host for Q. nova.The genus Eucalyptus is one of the most characteristic genera of the Australian flora and contains about 300 species. These trees have economic value due to their use in many sectors. The export of eucalyptus seed project was started by the Australian government and the FAO (1980) in 1960 and a great deal of eucalyptus seeds were introduced into numerous developing countries without any phytosanitary certificate (Cooper, 1983). It is estimated that about 15,000-20,000 species of phytophagous insects feed on Eucalyptus spp. in Australia (Majer et al., 1997). Some of these pests were accidentally introduced into developing countries during this project.
