ISPM 4 REQUIREMENTS FOR THE ESTABLISHMENT
OF PEST-FREE AREAS
ISPM 26 ESTABLISHMENT OF PEST FREE AREAS FOR
FRUIT FLIES (TEPHRITIDAE)

EPPO-NEPPO Workshop on Surveillance Zéralda, Algeria, 2012–09-18/20
ISPM 4 provides elements on the
requirements for the establishment and use
of pest-free areas (PFAs)
As a risk management option for phytosanitary
certification of plants, plant products and
other regulated articles exported from the PFA
To support the scientific justification for
phytosanitary measures taken by an importing
country for protection of an endangered PFA
ISPM 26 provides elements on the
requirements for the establishment and use
of pest-free areas (PFAs) for Fruit Flies (FF)
Scope ISPM 4 & ISPM 26
Definition of a pest free area PFA
IPPC glossary of phytosanitary terms
(ISPM 5):
« an area in which a specific pest does not
occur as demonstrated by scientific
evidence and in which, where
appropriate, this condition is being
officially maintained »
Three types of PFAs
• an entire country
• an uninfested part of a country in which a limited infested area is present
• an uninfested part of a country situated within a generally infested area.
General requirements for pest-free areas: determination of a PFA
Main criteria for the delimitation of the PFA:
biology of the pest Determines
scale at which it is possible to define a PFA
the types of boundaries by which it can be delimited.
In principle, delimitation is in close
relation with the occurrence of the
pest.
In practice, PFAs are generally
delimited by readily recognizable
boundaries coinciding with the pest's
biological limits (administrative,
physical features etc) . Apple and pear and fruit fly distribution in China (source Report of the assessment of northern China’s fruit fly pest free areas: available online at http://www.daff.gov.au
• Systems to establish freedom
• Phytosanitary measures to maintain freedom
• Checks to verify freedom has been maintained.
Establishment and Maintenance of a PFA
the biology of the pest
relevant PFA characteristics
level of phytosanitary security required
These three components will vary according to:
• General surveillance
Acceptable for PFA as entire country, not sufficient for the other situations
Establishment and Maintenance of a PFA: systems to establish freedom
Literature, Internet surveys
NPPOs, national and local
governmental agencies
research institutions, universities,
scientific societies
Pest free status
Producers, consultants
Museum general public
• Specific surveys Delimiting and detection surveys are
needed for a PFA in a country where
pest is present (e.g. for FF trapping with
specific density and servicing, fruit sampling )
Regulatory action such as:
• Inclusion on a quarantine pest list
• import requirements
• restriction of the movement of certain products within areas of a country or countries (including buffer zones) in particular for situations where the pest is present in part of the country
• routine monitoring
• extension advice to producers
Establishment and Maintenance of a PFA: Phytosanitary measures to maintain freedom
• ad hoc inspection of exported
consignments
• requirement that
researchers, advisers or
inspectors notify the NPPO of
any occurrences of the pest
• monitoring surveys
Establishment and Maintenance of a PFA: Checks to guarantee freedom has been maintained
General requirements for FF pest-free areas: important element is public awareness
