Surveillance: An official process which collects and records data on pest presence or absence by survey, monitoring or other procedures [CEPM, 1996; revised CPM, 2015] (ISPM 5 Glossary of Phytosanitary terms)

Surveillance should be used to determine the distribution of a pest in an area as a basis for the further consideration of whether the pest is not widely distributed (Supplement 1 “Guidelines on the interpretation and application of the concepts of “official control” and “not widely distributed” to ISPM 5 Glossary of phytosanitary terms).

delimiting survey: Survey conducted to establish the boundaries of an area considered to be infested by or free from a pest [FAO, 1990] (ISPM 5 Glossary of phytosanitary terms)

detection survey: Survey conducted in an area to determine if pests are present [FAO, 1990; revised FAO, 1995] (ISPM 5 Glossary of phytosanitary terms)

monitoring survey: Ongoing survey to verify the characteristics of a pest population [ISPM 4, 1995] (ISPM 5 Glossary of phytosanitary terms)

survey (of pests): An official procedure conducted over a defined period to determine the presence or absence of pests, or the boundaries or characteristics of a pest population, in an area, place of production or production site [FAO, 1990; revised CEPM, 1996; CPM, 2015; CPM, 2019] (ISPM 5 Glossary of phytosanitary terms)

IPPC Guides and training materials
  • Plant Pest surveillance Guide: This resource presents a guide to understanding the principal requirements of surveillance programmes for national plant protection organizations (NPPOs). This resource aims to provide information to support the surveillance activities that NPPOs need to undertake as part of national phytosanitary systems and as obligations under the IPPC.
