Overview of the evaluation of Nipaecoccus viridis for bare rooted plants
Rating of the likelihood of pest freedom Pest free with some exceptional cases (based on the Median)
Percentile of the distribution 5% 25% Median 75% 95%
Proportion of pest‐free plants 9,844 out of 10,000 plants 9,923 out of 10,000 plants 9,958 out of 10,000 plants 9,981 out of 10,000 plants 9,995 out of 10,000 plants
Percentile of the distribution 5% 25% Median 75% 95%
Proportion of infested plants 5 out of 10,000 plants 19 out of 10,000 plants 42 out of 10,000 plants 77 out of 10,000 plants 156 out of 10,000 plants
Summary of the information used for the evaluation Possibility that the pest could become associated with the commodityThe pest is present around the nursery on different host plants and can spread to and within the nursery. Ficus carica is a well‐known host plant for the pest and the pest can be associated with the bark.Measures taken against the pest and their efficacyThe measures taken against the pest (pesticide treatment, weed control and inspections) are efficient and effective, although there could be issues related to reaching the mealybugs when hidden in crevices or in soil.Interception recordsIn the EUROPHYT database, there are no records of notification of Fcarica plants for planting from Israel due to the presence of N. viridis between the years 1995 and November 2019 (EUROPHYT, online).Shortcomings of current measures/proceduresThe fields designated for export are not isolated from other fields in the nursery and from the surroundings. The soil inspection for mealybugs is difficult to perform.Main uncertaintiesThe main uncertainties are the pesticide applications that may have limited efficacy on the bark, which can be covered by leaves, and in crevices/soil. Other uncertainties concern the detection of crawlers during inspection and the lack of information on the density of the pest in the surrounding areas.
