Non-native beetles trapped at entry points in Spain
Two recent articles report on surveillance programme on beetles in Spain. A multiannual surveillance programme was carried out from 2017 to 2021 with baited traps at five Spanish ports (Alicante, Castellon de la Plana, Gandia, Sagunto, and Valencia), targeting non-native bark and ambrosia beetles, as well as longhorn beetles. In another study carried out from 2013 to 2022, traps were placed in all the international ports and wood processing sites of the Valencia region, as well as in the nearby forested areas. The following non-native beetles were caught:
Species | Family/subfamily | Specimen numbers | Comments |
Coccotrypes dactyliperda | Scolytinae | 432 | Trapped in Alicante, Castellon de la Plana, Gandia, Sagunto, and Valencia (port and surrounding area) |
Dactylotrypes longicollis | Scolytinae | 2 | Trapped in Valencia (port) |
Gnathotrichus materiarius | Scolytinae | 1 | Trapped in Sagunto (port) |
Hypothenemus eruditus | Scolytinae | 3 | Trapped in Castellon de la Plana and Gandia (surrounding area) |
Ips calligraphus | Scolytinae | 4 | Trapped in Valencia (port) in 2019 |
Ips grandicollis | Scolytinae | 1 | Trapped in the forest near Valencia in 2014 |
Xyleborus bispinatus | Scolytinae | 29 | Trapped in Castellon de la Plana and Gandia (surrounding area) |
Xylosandrus germanus | Scolytinae | 16 | Trapped in Gandia (surrounding area) |
Xylotrechus stebbingi | Cerambycidae | 8 | Trapped in Gandia, Sagunto, and Valencia (port) and Castellon de la Plana (surrounding area) |
After the capture of Ips calligraphus in August 2019, several field surveys were carried out in 2021 to search for signs of establishment of the species. Additional traps were installed, but no further specimens were detected. Similarly, no other specimens of I. grandicollis were trapped after 2014. The authors noted that these species had probably been transported through international trade from their native range, but consider that they are not established in Spain.
The pest situation of Ips calligraphus and Ips grandicollis in Spain can be described as: Absent, intercepted only.
