Firewood as a pathway for insect introductions. What are the risks of ant invasions in Patagonia?

Abstract

Firewood can act as a long-distance dispersal vector for wood-infesting insects both within and among countries. Recently, we have detected the alien carpenter ant Camponotus mus in firewood transported from central Argentina to Patagonia. This species generates significant economic losses in its native range and has invader potential. Moreover, global warming and the increasing anthropogenic disturbance in Patagonia make this region highly susceptible to insect invasions. This is especially alarming considering the current lack of sanitary controls of incoming goods. To prevent insect introductions via firewood it is crucial to implement a joint effort among the scientific community, control organisms, government, and end user.
