| Abstract:
Pests and pathogens can be moved from one region to another along natural and/or man-made pathways. To block, or at least to minimize, the threat of entry of exotic pests and pathogens along man-made pathways, governments take quarantine or regulatory actions. The objectives of this paper are first to review, in general terms, the various natural and man-made pathways and then to discuss more specifically the importation of cut flowers and ornamental plants as a man-made pathway. Regulatory actions or safeguards that might be exercised along this pathway to protect against the threat of entry are reviewed. Two such actions, i.e., inspection and exclusion, are reviewed as applied against exotic pest threats to the United States Inspection as a safeguard is discussed in the light of actual insect, mite, and snail interception data obtained from ports of entry. Exclusion as a safeguard is illustrated by rules and regulations designed to protect against potential entry of obscure exotic pathogens. | |
