Coleoptera Alien species avocado groves trapping networks early detection

Abstract

The rise of invasive species is a global concern, increasingly driven by international trade and climate change. Ambrosia beetles (Xyleborini) are particularly successful invaders due to their ability of asexual reproduction and symbiotic relationship with fungi. Here we report and map the distribution of Xyleborini alien species in the Iberian Peninsula, expanding knowledge about the distribution of already established species and identifying a new host plant for Xyleborus bispinatus. Some populations have been detected through early detection trapping networks. The presence of Euwallacea fornicatus and E. similis is confirmed for the first time in the Iberian Peninsula, with E. similis establishing populations in Southeastern Spain, while E. fornicatus is confirmed in the South, affecting avocado crops. Additionally, the distribution of X. bispinatus has been expanded. Amasa parviseta was also recorded, suggesting a broader distribution than previously known. The study highlights the increasing arrival and establishment of invasive Xyleborini in Spain, likely driven by trade, climate change, and urban development. This work underscores the urgent need for monitoring and early detection programs to manage and mitigate potential impacts.
