Summary of the information used for the evaluation |
Possibility that the pest could become associated with the commodity Lopholeucaspis japonica is a polyphagous armoured scale that feeds on plants belonging to 38 families, with Malus domestica being reported as a host. Crawlers can be dispersed by wind or insects (ants, flies and ladybirds), occasionally also by human transport. Plants for planting and cut branches are reported as possible pathways. It is present in Turkey. It was recorded on Citrus spp. Up to date, there is no record on apple in Turkey. It was detected in the Black Sea region (Artvin, Giresun, Ordu, Samsun, Trabzon, Rize provinces) (Kaydan et. al., 2013); however, there is no L. japonica pest‐free area in Turkey. Measures taken against the pest and their efficacy The relevant proposed measures are: (i) Inspection, certification and surveillance, (ii) Roguing and pruning, (iii) Pesticide application, (iv) Natural biological control, (v) Refrigeration and (vi) Pre‐consignment inspection. Interception records There are no records of interceptions from Turkey. Shortcomings of current measures/procedures Low initial infestations might be overlooked and macroscopic misidentification is possible. Chemical applications can affect biological control agents. Chemicals are applied targeting mainly crawlers, however, no details are given on which pesticides are applied from those listed in Dossier, Section 2.0, on the pesticide application schedule and on the application methods. Low storage temperature can prevent or slow down the development of the pest but will not eliminate it. Main uncertainties – No records of L. japonica on Malus are available. – It is unclear whether the pesticides are applied on a calendar basis or following ad hoc application as function of pest presence, or both – Screening of certified material for this pest could not ensure pest absence because young stages can be difficult to detect. – The pest was detected in the Black Sea region, however no pest‐free area is determined in Turkey. |
