Abstract

Myocastor coypus (Molina, 1782) - the coypu is large, herbivorous, semiaquatic rodent native to South America that has been introduced to Africa, Asia, North America and Europe. Coypus have been widely farmed for their fur in the beginning od 20th century, during the last century there have been numerous escapes from captivity, some animals were also deliberately released from farms. In wild this species establishes self-sustaining populations and creates damage to autochthonous species, ecosystems, agriculture, irrigation systems and riverbanks by it's burrowing activity. Coypu is herbivorous generalist that mostly feeds on aquatic plants, as a result of such feeding it can alter natural habitats. Coypu threatens plant species as well as aquatic birds, fish and invertebrates. For these reasons coypu is on the list of the 100 world's worst invasive alien species. Invasive alien species rank among the world's greatest threats to biodiversity and cause huge economic losses to human activities. Eradication is a key management option for preventing the impact of biological invasions of pest species. Some countries have tried to solve this problem through control and eradication campaigns. In UK eradication campaign (1981.-1989.) was declared successful. In Italy it was not possible to carry out eradication, therefore permanent control campaign started in 1995. Today this invasive rodent species can still be found in Italy. Even though eradication solves problems made by introducing invasive alien species, it is frequently discarded due to the high costs.
