Abstract:
We compared the efficacy of 2 endemic strains of entomopathogenic nematodes isolated from Hermiston, OR, with that of 3 exotic nematode species for control of Colorado potato beetle, Leptinotarsa decemlineata (Say). In laboratory experiments, the exotic Heterorhabditis species were more pathogenic to Colorado potato beetle than were the endemic Heterorhabditis strains. Exotic Steinernema species were less pathogenic to Colorado potato beetle than the exotic Heterorhabditis species. No Colorado potato beetle adults emerged from soil treated with H. marelatus Liu & Berry, a new species collected from Seaside, OR. Nematode pathogenicity was detected up to 14 wk after application in Galleria mellonella (L.) in soil taken from field plots treated with endemic and exotic nematode species.Document Type: Research article
