First record of Ektaphelenchoides pini associated with Ips sexdentatus on Pinus nigra laricio in Italy

In February 2015, an unexpected windstorm downed five hectares of a European black pine Pinus nigra subsp. laricio forest formation located close to Vallombrosa, Florence (Central Italy). In the following spring, an extensive survey was conducted in the area. Felled trees, stumps and all the suitable plant material were screened for the presence of the pinewood nematode (PWN), Bursaphelenchus xylophilus, by sampling wood and bark. Bark beetles were then collected from the gallery systems on the inner side of bark samples and observed in the laboratory. The following bark beetles were morphologically identified: Ips sexdentatus, Orthotomicus erosus, O. laricis and Pityogenes bidentatusa. The dissection of Ips sexdentatus allowed the extraction of numerous nematodes that were morphologically and molecularly identified as Ektaphelenchoides pini. Conversely, only few nematode specimens were isolated from either pine bark or wood. These individuals could be only molecularly identified and belonged to an undescribed nematode taxon. Even though no PWN was recorded in the investigated sites, our survey allowed the detection of a new association between E. pini and I. sexdentatus on P. nigra.

“…Even though regarded as a minor pest with little economic importance, infestations have been observed in declining or dying stands weakened by diseases, nutrient deficiencies, mechanical injury or previous insect attacks (VIEDMA 1964;LIEUTIER et al, 2016;CABI, 2018). In these conditions infestations are often heavy (BROWN and LAURIE, 1968) and areas involved in reforestation are particularly at risk (BROWNE, 1986;ROBERTSON et al, 2008). In southeastern France, FABRE and CARLE (1975) reported it as a secondary pest of Pinus pinaster severely weakened by the scale insect Matsucoccus feytaudi Duc.…”

“…As many other scolytinae, H. ligniperda, in some circumstances, may be a significant pest not only directly, for its activity on host plants, but also indirectly as vector of nematodes carried under the elytrae (ROBERTSON et al, 2008). Associations have been observed with Bursaphelenchus sexdentati in Greece and Portugal (SKAR -MOUTSOS and SKARMOUTSOS, 1999;PENAS et al, 2006), B. tusciae in Portugal and Tunisia (PENAS et al, 2006;MEJRI et al, 2016), B. hellenicus in Italy andPortugal (PENAS et al, 2006;CARLETTI et al, 2008;D'ERRICO et al, 2015).…”

“…Tomicus destruens is frequently attracted to pine forests heavily stressed by drought, fire, or root diseases, and in some Mediterranean countries, it has been often reported as a major cause of pine mortality (LIEUTIER et al, 2016). Conversely, O. erosus, though being generally a secondary species breeding in logs or trees already colonized by more aggressive beetles, may sometimes attack plants weakened by stress factors such as fire or drought (ROBERTSON, 2008). Moreover, this beetle has been reported as a potential vector of several Bursaphelenchus species such as B. fuchsi (BRAASCH and PHILIS, 2002), B. fungivorus (ARIAS et al, 2005), B. teratospicularis (PENAS et al, 2006), B. sexdentati (CARLETTI et al, 2008) and B. minutus (TORRINI et al, 2017).…”

beetles (Coleoptera Curculionidae Scolytinae) associated with Pinus pinea in Lebanon: new records with remarks on their ecology, distribution and potential threat for forest stands. Five species of Scolytinae new to Lebanon were recorded on Pinus pinea: Hylurgus ligniperda (Fabricius), Hylurgus micklitzi Wachtl, Hylastes angustatus (Herbst), Hylastes attenuates Erichson, Carphoborus pini Eichhoff. Their ecology, distribution and potential phytosanitary risk are discussed in the context of stone pine conservation.

“…The nematode is transported between host trees almost exclusively by cerambycid beetles in the genus Monochamus . Other families of beetles besides Monochamus have been shown to carry PWN, but none has been shown to transmit it Kobayashi et al 1984;Robertson et al 2008).…”

En primer lugar, gracias a la entidad que ha financiado el proyecto del cual este estudio forma parte: proyecto europeo REPHRAME (FP7-KBBE-2010-4). Un trabajo de investigación es siempre fruto de ideas, proyectos y esfuerzos previos que corresponden a otras personas. Por todo ello, especial agradecimiento a mi tutor Juan A. Pajares por creer que mis ideas podrían significar un aporte interesante en este proyecto común y por su estímulo y ayuda para seguir creciendo como persona e intelectualmente. Por supuesto, muy importante agradecimiento a mi cotutor Iñaki Etxebeste que ha sido capaz de ganarse mi lealtad y admiración, por su predisposición permanente e incondicional a aclarar mis dudas y su inolvidable apoyo como amigo. Sin olvidar a Gonzalo Álvarez compañero de campo, tesis, y demás desayunos reconfortantes. Gracias tanto al equipo de Calabazanos como a Dani y Ana por ayudarme y acompañarme durante el rally de mi tesis. Estoy segura que en ninguna tesis puede faltar la inestimable ayuda de Celia con las peleas burocráticas, y no tan burocráticas. En la preparación remota, agradezco a mi familia que desde su sabiduría de la sencillez, me enseñaron el sentido de la vida y las ganas de luchar por lo que quiero. Recuerdo agradecido al club del té donde, preguntar y elaborar pequeñas respuestas con el gusto de aprender, nunca pudo ser más divertido. Gracias a todas las personas que durante este período han sido claves en mi vida, quienes por haber acudido siempre en mi auxilio ocupan un rinconcito en mis afectos, y quienes han arreglado el mundo tantas veces conmigo. Y por haberlo hecho posible, teniendo que hacer lo imposible, especial agradecimiento a Lu y Ari por disolverse conmigo en algo absolutamente grande…
