摘要

The giant African snail Achatina fulica Bowdich, 1822 was introduced into Paraná, Brazil, in the 1980s. Since then, it has spread across the country, despite its known invasive status on a global scale. The main objective of this study was to assess the problems faced in the management of the giant African snail. To accomplish that, we gathered and analyzed information available on the internet, scientific databases, field studies, as well as interviews and consultations with official agencies, NGOs, museums, the scientific community and people that coexist with the species. Despite the fact that extensive information has been generated regarding A. fulica (1,340 articles, 65 summaries in national annals, 40,700 pages on the internet), essential to promote control measures to hinder the propagation of this species, the majority of the available information remains inaccessible to the world at large. Moreover, the environmental, economic and health impacts of this species remain unclear, which may contribute to discouraging the initiation of management actions. Finally, control measures are still inefficient due to the generalist profile of this species and the lack of knowledge concerning its biology and ecology. Thus, in conclusion, even though A. fulica has been an invasive species for over a century in many other countries, it is difficult to find evidence supporting the need to subsidize its management. This may be an indication that many other, poorly known exotic species will have time and the proper conditions to become established and cause problems before they come to be recognized as invasive.
