AB  - Potato cyst nematodes (PCNs) are a major pest of solanaceous crops such as 
      potatoes, tomatoes, and eggplants and have been widely studied over the last 30 
      years, with the majority of earlier studies focusing on the identification of 
      natural hatching factors. As a novel approach, we focused instead on chemicals 
      involved in nematode orientation towards its host plant. A new dual choice sand 
      bioassay was designed to study nematode responses to potato root exudates (PRE). 
      This bioassay, conducted together with a traditional hatching bioassay, showed 
      that biologically active compounds that induce both hatching and attraction of 
      PCNs can be collected by water extraction of incised potato roots. Furthermore, 
      our results demonstrated that PCN also were attracted by potato root volatiles. 
      Further work is needed to fully understand how PCNs use host plant chemical cues 
      to orientate towards hosts. Nevertheless, the simple attraction assay used in 
      this study provides an important tool for the identification of host-emitted 
      attractants.
