Santos, 27 de agosto a 01 de setembro de 1995.  aClassical biological control involves the introduction, establishment and colonization of natural enemies to reduce damages caused by pest organisms. It is commonly conducted when effective, pre-established biocontrol agents are not available or when the summed effects of available agents is not enough to prevent significant pest damage. Most countries with intensive biocontrol activities regulate the importation and exportation of natural enemies to reduce the chances of unintentional introductions of undesirable organisms in those processes. Regulations are expected to fulfill its main goal, but should not be excessively restrictive to hinder biocontrol activities. FAO has dedicated itself to contribute to the establishment of guidelines that member countries could adopt or base themselves when defining their national regulations. Brazil is also developing its own protocol, which at the same time has been discussed with neighboring countries in the South for a harmonization of the rules. Regionally accepted protocols should always be considered, because political boundaries, and a natural enemy released in a country may easily spread into neighboring countries which share given ecosystems.  ainternational cooperation  anatural enemies  apathogens  apest control  aBiocontrol agents  aPest insects  aRegulations1 aSA, L.
