First report of Tuta absoluta in a tomato crop in Guernsey
In Guernsey, Tuta absoluta (Lepidoptera: Gelechiidae – EPPO A2 list) was first found at a packing unit in June 2010 (EPPO RS 2010/138), but until recently no further specimens were found on the island. In October 2012, 2 adult males of T. absoluta were caught in a pheromone trap placed in one commercial glasshouse of tomatoes (Solanum lycopersicum). This finding was made during a routine survey. No symptoms or damage were seen in the infested tomato crop. Investigations are being made to trace back the possible origin of this introduction. Phytosanitary measures were taken to eradicate T. absoluta and included: intensive trapping plus chemical treatments; disposal of the crop, growing medium and floor covering after the final harvest.
The pest status of Tuta absoluta in Guernsey is officially declared as: Present, detected in one commercial glasshouse, under eradication.
