N	Risk mitigation measure	Effect on the pest	Evaluation and uncertainties
1	Registration of production sites	Yes	As the plant passport is very similar to the EU one, the plants shall be free from quarantine pests and RNQPs. Uncertainties: – None.
2	Physical separation	No	Not relevant. Physical separation is not a barrier for B. tabaci because the adults can fly.
3	Certified plant material	Yes	Only applicable to seedlings with leaves.
4	Growing media	No	Not relevant
5	Surveillance, monitoring and sampling	Yes	Although the plants are thoroughly checked during the production, later infestation by B. tabaci can go undetected. Uncertainties: – Capacity of detection of the pest on the older plants with many leaves.
6	Hygiene measures	Yes	Weeding can have some effect on the reduction of Bemisia populations. The other measures are not relevant. Uncertainties: – None.
7	Removal of infested plant material	Yes	Removal of infested plant material can have some effect on the reduction of Bemisia populations. Uncertainties: – None.
8	Irrigation water	No	Not relevant.
9	Application of pest control products	Yes	Chemical measures may have some effect on the pest. Uncertainties: – The active ingredients of chemical treatments and their level of efficacy against the pest.
10	Measures against soil pests	No	Not relevant.
11	Inspections and management of plants before export	Yes	Although the plants are thoroughly checked 2 weeks before the export, infestation by B. tabaci can go undetected. Uncertainties: – Capacity of detection of the pest on the older plants with many leaves.
12	Separation during transport to the destination	No	Not relevant. Plants are not individually separated during transportation. The pest can infest other plants.
