Summary of the information used for the evaluation

Possibility that the pest could become associate with the commodity

M. parallela is extremely polyphagous and causes most damage in its native range to Quercus spp., Prunus spp., and Malus spp. Significant damage also occurs on various other woody species, including many native species of Central Asia. Malacosoma parallela is present in Turkey, with no further details on its distribution.

M. parallela can spread by flights of adult moths. All stages of the life cycle can be transported on host plants moving in trade, particularly plants for planting and cut branches. Eggs, larvae and pupae (cocoons) may be associated with wood carrying bark and may be present as contaminants on other commodities.

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 of M. domestica plants for planting from Turkey

Shortcomings of current measures/procedures

Egg masses might be overlooked by non‐trained personnel.

Some of the pesticides listed in the dossier might be effective against the moth. 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 temperatures can slow down its development but not kill the insect.

Main uncertainties

– The pest is reported in Turkey with no details on its distribution

– Egg masses might be overlooked by non‐trained personnel

– The insecticide applications are not targeted to M. parallela and may not be effective
