“…The insect vector Monochamus galloprovincialis is known to occur well inside the centre of the country, quite far (ca 200-300 km) north of the Setúbal Peninsula, for example, in the region of Penacova, near Coimbra. Furthermore, it is known to occur throughout the continental territory (Sousa et al, 2001(Sousa et al, , 2002Penas et al, 2006). On the other hand, continental isolate BxPt73FZ has a separate position from all other isolates, suggesting a new introduction in continental Portugal, possibly from the native North American population.…”

The pine wood nematode (PWN), Bursaphelenchus xylophilus, the causal agent of pine wilt disease (PWD), is a major world-wide pathogen and pest of pine, with impacts on forest health, natural ecosystem stability and international trade. In Portugal, PWN was first diagnosed in 1999, the first occurrence also for Europe. The disease was recently detected on the island of Madeira and in northern Spain. In an attempt to search for more reliable and robust molecular markers that enable the study of intraspecific variability of B. xylophilus from different geographic locations, the intergenic spacer (IGS) region of the 5S rRNA gene and inter-simple sequence repeats (ISSR) analysis were used to determine the genetic relationships among 43 B. xylophilus isolates from Portugal, China, Japan, South Korea and USA. IGS sequence analysis showed that this region can only be used to establish interspecific relationships, since no differences were detected among Portuguese isolates from different geographic locations. Fingerprints obtained with ISSR show high genetic variability among Portuguese isolates, except for the ones obtained prior to 2008. The ISSR dendrogram suggests the spread of the disease inside continental Portugal and to Madeira. Until 2008, B. xylophilus populations found in continental Portugal showed low genetic diversity, pointing to a single introduction, probably from Asia, whereas recent populations from continental Portugal (2009-2010) and Madeira show high genetic diversity, suggesting multiple introductions from different origins.

Pine volatiles and terpenoid compounds attractive to European xylophagous species, vectors of Bursaphelenchus spp. nematodes

et al. 2009

The attractiveness of different combinations of volatile compounds to several scolytid and cerambycid species, potential vectors of phytoparasitic nematodes of the genus Bursaphelenchus Fuchs, was investigated in pine woods of central Italy. The blend composed of α-pinene, ethanol, ipsenol, ipsdienol and 2-methyl-3-buten-2-ol was very efficient in trapping the cerambycids Monochamus galloprovincialis, Acanthocinus griseus and Arhopalus syriacus and the scolytids Ips sexdentatus, Orthotomicus erosus and Hylurgus ligniperda. This blend is proposed for operational surveys of Bursaphelenchus spp. associated with these beetles. Comparison of the capture levels with cross-vane and funnel traps baited with α-pinene, ethanol, ipsenol, ipsdienol, 2-methyl-3-buten-2-ol and cis-verbenol revealed the higher efficacy of the cross-vane traps for the abovementioned cerambycids and the scolytid I. sexdentatus but greater effectiveness of the funnel traps in capturing H. ligniperda and O. erosus. Cross-vane traps were more efficient in capturing large numbers of these insects. Data on non-target xylophagous beetles and predator species are also reported.

“…Various Monochamus species can carry B. xylophilus, particularly M. carolinensis (Olivier) in North America (Dropkin et al 1981;Linit et al 1983;Linit 1988), M. alternatus (Hope) in infested regions of Asia (Mamiya 1972;Lee et al 1990;Chang et al 1995;Yang 2004) and M. galloprovincialis (Olivier) in Portugal (Evans et al 1996;Sousa et al 2001;Sousa et al 2002;Penas et al 2006). The latter species is mostly found on pine trees in southwestern Europe and North Africa but it also occurs in North and Central Europe (Hellrigl 1971, see also http://www.faunaeur.org/).…”
