Abstract
Globodera pallida, the pale cyst nematode (PCN), is a quarantine pest of potato posing a serious threat to the Idaho potato industry. Globodera pallida only hatches in the presence of a hatching stimulus produced by a host plant or closely related species. In the absence of this hatching stimulus, G. pallida can remain viable in the soil for decades. A trap crop stimulates hatch of G. pallida but is a nonhost, which means the nematode cannot develop or reproduce. This study evaluated the trap crop potential of several solanaceous species by determining G. pallida host status and hatching effect of each species. The species under investigation included Solanum aethiopicum, S. macrocarpon, S. quitoense, S. retroflexum, and S. douglasii. All species were determined to be nonhosts of G. pallida. The most promising trap crop candidates with a hatching stimulatory effect comparable to potato were S. quitoense and S. retroflexum. Further research is needed to assess whether these species could be effective G. pallida trap crops under Idaho field conditions.
