Abstract	International ports are considered as sites at high-risk for the introduction of alien wood-boring beetles. Invasive alien species cost billions of euros every year, the early detection has become of utmost importance. The main aim of this study is to improve and optimize the protocol already existing for alien wood-boring beetles interceptions. In particular we investigated: a) how the degree of isolation of the traps within the port area can affect alien and native wood-boring beetles richness and abundance; b) if and how the wood-boring beetles species richness and abundance change in time, both within the same year and among years. We selected five international Italian ports that were monitored for three years (2012-2014): Genova (44°24'00''N 8°55'12''E), Ancona (43°37'39''N 13°30'09''E), Salerno (40°39'52''N 14°44'41''E), Ravenna (44°29'00''N 12°17'00''E), and Napoli (40°50'00''N 14°15'00''E). Three multi-funnel traps baited with a multi-lure blend (apinene, ethanol, ipsdienol, ipsenol, methylbutenol), were set up in each port. We identified both alien and native Scolytinae, Cerambycidae and Buprestidae beetles. The results demonstrated that: a) the exotic species richness and abundance were similar among years, indicating that the type and quantity of imported goods did not clearly change in time; b) captures of exotic species are probably influenced more by the proximity of the traps to storage locations of woody materials than to their degree of isolation; c) the exotic species richness and abundance change randomly within years, indicating that traps installation period should cover the entire period when wood boring beetles can be active (April-October). In conclusion, this study confirmed the importance of such protocols for the early-detection of alien wood-boring beetles and underlined that a better comprehension of how woody material are stocked in ports is necessary to decide the optimal location of traps.
