Express PRA for Pinnaspis strachani


The scale Pinnaspis strachani presumably is endemic in Asia and already occurs in protected cultivation in Germany and the Member States Hungary, Italy, Poland and possibly in Great Britain (not confirmed). So far, the species is listed neither in the Annexes of Directive 2000/29/EC nor by EPPO. P. strachani is extremely polyphagous. Until today, 244 host plants out of 74 plant families are known. Occasionally the species is able to cause economically relevant damage on Citrus, Hibiscus, palm, coconut, mango, manioc, banana and grapefruit. Due to unsuitable climatic conditions, it is assumed that P. strachani is not able to establish outdoors in Germany and in the EU. In the EU, the species is reliant on host plants in protected cultivation (greenhouses, tropical greenhouses, indoor plants). The scale has a very limited natural spread capacity. Since P. strachani is not able to establish outdoors in the EU, the spread capacity is very limited and normally, an infestation is easy to eradicate. Thus, the scale poses only a low phytosanitary risk to Germany and other EU-Member States. Based on this risk analysis the risk by P. strachani is assessed as low. Thus, P. strachani is not classified as a potential quarantine pest and § 4a of the Plant Inspection Order does not apply.
