First report of Bursaphelenchus hellenicus Skarmoutsos, Braasch, Michalopoulou (Nematoda: Aphelenchoididae) from Turkey

Abstract

A survey was conducted in forest sites of the Mu gla Regional Forest Directorates for the presence of the pinewood nematode, Bursaphelenchus xylophilus. Wood samples were collected from declining pine and cedar trees. A total of 207 samples were taken, and nematodes were extracted, observed and identified. The pinewood nematode was not detected, but another Bursaphelenchus species was recovered from the wood of a Pinus brutia tree in Es ßen-Karadere location in Fethiye, which strongly resembled the original description of B. hellenicus. It was identified as this species by morphology and ITS-RFLP. Measurements and diagnostic features are presented. This is the first report of B. hellenicus from Turkey. Materials and methodsIn 2007, a survey was conducted in the conifer forests of south-western Turkey including the Mu gla Regional Forestry Directorate. Samples were taken primarily from Pinus species; however, a few samples were collected from Cedrus libani A. Rich (Table 1). Two wood samples, 40-80 g, were collected from opposing sides of the trunk of each declined or wilted

Preliminary survey of nematodes associated with broadleaved trees in İzmit Forest Management Directorate, Turkey

“…Bursaphelenchus species in coniferous forests of Turkey (Akbulut et al, 2006;Akbulut, Braasch et al, 2007;Akbulut, Elekcioglu et al, 2007;Akbulut, Vieira et al, 2008;Akbulut, Elekcioglu et al, 2008;Akbulut, et al, 2013…”

“…Therefore, survey studies were carried out to investigate the presence of the pinewood nematode in the coniferous forests of Turkey. As a result of these studies, several Bursaphelenchus species were identified from conifer tree species, but not B. xylophilus (Akbulut et al, 2006; Akbulut, Braasch et al, 2007; Akbulut, Elekcioglu et al, 2007; Akbulut, Vieira et al, 2008; Akbulut, Elekcioglu et al, 2008; Akbulut, et al, 2013).…”

Survey for the detection of Bursaphelenchus insect-vector species in the western part of Turkey

“…anamurius, B. andrassyi, B. hellenicus, B. mucronatus, B. pinophilus, B. sexdentati andB. vallesianus, (Akbulut et al, 2006, Akbulut et al, 2007;Akbulut et al, 2008a;Akbulut et al, 2008b;Akbulut et al, 2013, Dayi et al, 2014. However, no insect species have been reported as vectors of these Bursaphelenchus species in Turkey except the report of M. galloprovincialis as the vector of B. mucronatus (Akbulut et al, 2010).…”

“…Similar results were also observed during the survey of B. xylophilus. Since 2002, over 3000 wood samples around Turkey were taken from dead or dying conifer species, and only 5 % of the total samples was contained Bursaphelenchus species with limited number of individuals (Akbulut et al, 2006;Akbulut et al, 2007;Akbulut et al, 2008a;Akbulut et al, 2013). All reported Bursaphelenchus species are believed to be native to Turkish conifer forests, and no extensive wilting symptoms caused by these Bursaphelenchus species have been observed so far.…”

New observations on occurrence and distribution of Bursaphelenchus spp. (Nematoda: Aphelenchoididae) in conifers in Romania

“…As a consequence, several monitoring surveys are continuously performed in natural forests, yielding new observations on the distribution of Bursaphelenchus spp. all over the world and description of new species of the genus (Philis & Braasch, 1996; Braasch and Schmutzenhofer, 2000; Pedram et al., 2011, Akbulut, Braasch, & Cebeci, 2013; Inácio et al. 2015; Inácio, Nóbrega, Mota, & Vieira, 2017; Miraeiz et al., 2015; Tomalak and Pomorski, 2015; etc.).…”
