Dr Gordon Port is a senior lecturer at Newcastle University, specialising in invertebrates with a particular interest in how invertebrates find their food. Here Gordon talks about the most common slug species in the UK, including those most likely to be found damaging crops, the most notorious being the grey field slug. He then goes on to describe how slugs seek out their food sources, based on various research studies he has conducted. Slugs will literally bump into a food source before responding to it rather than being attracted at a distance to a specific food source. To learn more, visit www.certiseurope.co.uk/slugforce
