Distribution

Species of Nearctic origin was recorded for the first time in Europe in Lombardy (North Italy) in 2003 ( Pennacchio et al. 2004). The species seems to present a very limited dispersal capability, not having substantially expanded its distribution range in nearly 10 years. The establishment of P. liminaris in Italy is confirmed by the collection of this single male specimen (Fig. 2 ; Fig. 11 ). Phloeotribus liminaris has also been recently intercepted in France, where, however, it is not naturalised ( Barnouin et al. 2020).

Notes

Phloeotribus liminaris was captured using bottle traps baited with red wine and placed at about 2.5 m from the ground (see Ruzzier et al. 2021a).

Hosts

Despite the species being considered of potential phytosanitary interest for Mediterranean Prunus spp. ( Rosaceae ) ( Pennacchio et al. 2004), to date, no ecological or economic impact caused by Phloeotribus liminaris has ever been recorded in Italy.
