Ms Geraldine O'Sullivan:

It is continually moving northwards. There is surveillance and monitoring. Biological controls have successfully been used with the European beetle in that they have slowed the spread of it, but it is spreading. I will provide a map to the committee afterwards from the Scottish survey, which shows how it is moving in each year of the survey and the different locations it has been found. Again, we do not know about the consistency or volume of what exactly is involved in the survey but there is information and ongoing surveillance and monitoring.
