In the autumn of 2014 many companies specialized in protected lettuce cultivation were confronted with severe plant damage. In several lettuce greenhouses garden centipedes were detected. This explorative study summarizes the available knowledge of garden centipedes, and describes new possibilities for their control (chapter 1). It also tested one of the new control options, i.e. luring the garden centipedes with CO2-capsules, in a laboratory set-up (chapter 2). At the concentration tested, no luring effect of the CO2-capsules on the garden centipedes could be detected.At the same time it was found that many damaged lettuce plants suffered from Fusarium root damage. From research by the NVWA (Netherlands Food and Consumer Product Safety Authority) Fusarium was eventually identified as F. oxysporum lactucae. Finally, this seemed to be the most important culprit of the observed plant damage.
