Alien Invasive species are considered the principal threat to the unique flora and fauna of the Galapagos Islands. However little is known about the impact of alien invasive insects on indigenous Galapagos insect populations.
Presently, almost 480 alien insect species are registered for Galapagos, which represents about a quarter of the total Galapagos insect fauna. At least six species became invasive and pose a serious threat to the Galapagos biota, including two fire ant and wasp species, a mealybug and a parasitic fly.
With the help of a newly developed prioritisation model, the ecological impact and the potential invasiveness of the remaining alien and quarantine species is being evaluated. Initial results indicate that an additional 50+ alien species may become invasive in the near future.
The 1998 list of introduced insects is available in pdf format.
