Resumen

In February 2005, during follow-up inspections after import, palm trees of the species Thrinax parviflora were found infested with Darna trima (Lepidoptera). The palms were imported from Indonesia and the infestation was most likely introduced with these plants. The infested plants were present in a greenhouse where ornamental plants were grown. All plants in the greenhouse were chemically treated according to a schedule in order to eradicate the insect. The progress of the eradication was monitored with light traps in the greenhouse. The treatments were effective in eradication of the organism.

Peligro

The infested plants were detected in February 2005 during follow-up inspections after import. It is the first finding of Darna trima in The Netherlands. Darna trima is not listed as a quarantine organism in the EU, and its harmfulness was not assessed either by the EU. In an initial assessment carried out by the Netherlands Plant Protection Service this insect was considered to be a possible phytosanitary risk. D. trima is a nuisance to humans, as the stinging spines of the larvae may cause skin irritation. It is the intention to carry out a full PRA.
