摘要: Entomopathogenic nematodes are widespread in nature and commonly used the biological control of insect pests. However, we understand little about how these organisms disperse. We show a laboratory setting that entomopathogenic nematode Heterorhabditis marelatus is phoretically dispersed by non-host organism, isopod Porcellio scaber. These species both inhabit tunnels excavated roots lower stems bush lupine (Lupinus arboreus) nematodes' primary prey, larvae ghost moth Hepialus californicus. Phoretic dispersal via P. scaber may play role metapopulation dynamics this nematode.
