Division (2) Probability of spread in Great Britain of the pestF1

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:

1. (a)

   the number of life cycles of the pest on the hosts concerned;

2. (b)

   the biology, epidemiology and survival of the pest;

3. (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;

4. (d)

   subsequent infestation and transmission of the pest from the host concerned to other plants and vice versa;

5. (e)

   climatological factors;

6. (f)

   cultural practices before and after harvest;

7. (g)

   soil types;

8. (h)

   susceptibility of the host concerned and relevant stages of host plants;

9. (i)

   presence of vectors for the pest;

10. (j)

    presence of natural enemies and antagonists of the pest;

11. (k)

    presence of other hosts susceptible to the pest;

12. (l)

    prevalence of the pest in Great Britain;

13. (m)

    intended use of the plants.
