SECTION 4U.K.Criteria to identify pests which qualify as a [GB] regulated non-quarantine pest as referred to in Articles 36 and 38
(1)Identity of the pestU.K.
The pest shall meet the criterion defined in point (1) of Section 1.
(2)Probability of spread in [Great Britain] of the pestU.K.
The transmission of the pest shall be assessed to take place mainly via specific plants for planting, rather than via natural spread or via movement of plant products or other objects.
That assessment shall include, as appropriate, the following aspects:
(a)
the number of life cycles of the pest on the hosts concerned;
(b)
the biology, epidemiology and survival of the pest;
(c)
possible natural, human-assisted or other pathways for transmission of the pest to the host concerned and pathway efficiency, including mechanisms of dispersal and dispersal rate;
(d)
subsequent infestation and transmission of the pest from the host concerned to other plants and vice versa;
(e)
climatological factors;
(f)
cultural practices before and after harvest;
(h)
susceptibility of the host concerned and relevant stages of host plants;
(i)
presence of vectors for the pest;
(j)
presence of natural enemies and antagonists of the pest;
(k)
presence of other hosts susceptible to the pest;
(l)
prevalence of the pest in [Great Britain];
(m)
intended use of the plants.
(3)Potential economic, social and environmental impact of the pestU.K.
Infestations of the plants for planting referred to in point (2) with the pest shall have an unacceptable economic impact on the intended use of those plants as regards one or more of the following points:
(a)
crop losses in terms of yield and quality;
(b)
extra costs of control measures;
(c)
extra costs of harvesting and grading;
(e)
losses due to the necessity of growing substitute plants;
(f)
effects on existing production practices;
(g)
effects on other host plants at the place of production;
(h)
effects on the establishment, spread and impact of other pests due to the capacity of the pest concerned to act as a vector for those other pests;
(i)
effects on producer costs or input demands, including control costs and costs of eradication and containment;
(j)
effects on producer profits that result from changes in production costs, yields or price levels;
(k)
changes to domestic or foreign consumer demand for a product resulting from quality changes;
(l)
effects on domestic and export markets and prices paid;
(m)
effects on employment.
