Report of a Pest Risk Management: Dendrolimus superans
This summary presents the conclusions of the pest risk management which has been conducted on the pest,
according to EPPO Standard PP 5/4(1) Pest Risk Management Scheme.
Pest:
Dendrolimus superans Butler (Lepidoptera:
Lasiocampidae)
Assessors:
EPPO Panel on Quarantine Pests for Forestry
Date:
2003-09-28
IDENTIFICATION OF THE PATHWAYS
1 Pathways studied in the pest risk management
PATHWAY 1: Plants for planting
Plants for planting of host trees may carry eggs, larvae and cocoons of the pest on bark and branches.
PATHWAY 2: Cut branches (including Christmas trees)
Cut branches (including Christmas trees) of host trees may carry eggs, larvae and cocoons of the pest on bark
and branches.
PATHWAY 3: Wood with bark
Wood with bark of host plants may carry eggs and larvae of the pest.
PATHWAY 4: Isolated bark
Bark of host plants may carry eggs and larvae of the pest.
2 Other pathways
Natural spread has been identified as a pathway, but the Panel did not consider this case because of a long
distance between the actual area of distribution of the pest and the endangered area. It can nevertheless be noted
that this pathway may present a risk.
IDENTIFICATION OF POSSIBLE MEASURES FOR PATHWAYS
Pathway 1: Plants for planting of Abies, Pinus, Larix, Picea and Tsuga from countries where Dendrolimus
superans occurs
Measures related to consignments:
The following measures have been identified:
 plants for planting should be free from soil;
 visual inspection.
2
Measures related to the crop or to places of production
 plants for planting should be harvested and imported only in the period between 1st October and 31st
March;
 area freedom for Dendrolimus superans (high mobility pest);
 plants for planting should be grown in protected conditions.
Pathway 2: Cut branches (including Christmas trees) of Abies, Pinus, Larix, Picea and Tsuga from
countries where Dendrolimus superans occurs
Measures related to consignments:
The following measures have been identified:
 fumigation;
 visual inspection.
Measures related to the crop or to places of production
 cut branches should be harvested and imported only in the period between 1st October and 31st March;
 area freedom for Dendrolimus superans (high mobility pest).
Pathway 3 and 4: Wood with bark and bark of Abies, Pinus, Larix, Picea and Tsuga from countries
where Dendrolimus superans occurs
The pest is only present in Sakhalin and Kurile Island in Russia and Hokkaido and the North of Honshu in
Japan. As no trade of wood with bark or isolated bark form these areas exist, the Panel considered that there was
no need to identify phytosanitary measures. This may be subjected to revision if needed
OTHER POSSIBLE MEASURES
Because of the potential for natural spread surveys may be conducted in the areas near to infested areas, using
light traps to detect entry of the pest which would be followed by eradication campaigns. Control measures can
also be applied in adjoining infested areas, especially during outbreaks, to limit spread.
CONCLUSION: SELECTION OF MEASURES
Plants for planting of Abies, Pinus, Larix, Picea PC and, if appropriate, RC
and Tsuga originating in countries where
Free from soil according to EPPO Phytosanitary Procedure
Dendrolimus superans occurs
No.54
Harvested and imported only in the period between 1st
October and 31st March
or
Area freedom for Dendrolimus superans according to
EPPO Phytosanitary Procedure N°
or
Grown in specified protected conditions
Cut branches (including Christmas trees without PC and, if appropriate, RC
soil) of Abies, Pinus, Larix, Picea and Tsuga
originating in countries where Dendrolimus Harvested and imported only in the period between 1st
superans occurs
October and 31st March
or
Area freedom for Dendrolimus superans according to
EPPO Phytosanitary Procedure N°…
or
Fumigated by EPPO Phytosanitary Procedure N°

APPENDIX
For each possible category of measures in the pest risk management scheme, this table could identify
specifically the ones which were considered suitable ("possible" in bold) and the ones which were not suitable
(with a brief justification)
The Panel should decide whether such a summary table is useful, and whether it belongs to the pest risk
management, or to the report of the pest risk management
