Ghost moth caterpillars of Hepialus californicus (Lepidoptera, Hepialidae) feed upon lupine roots, are univoltine and largely monophagous at the study site at the Bodega Marine Reserve, Sonoma County, California.
Ecology of an entomopathogenic nematode, Heterorhabditis hepialus
hepialus nematodes were added to one-half of the pots, chosen randomly, in each caterpillar density; the other half of the pots for each caterpillar density lacked the nematode.
hepialus in April did we find this nematode in September when the plants were harvested.
Estimates of lupine mortality due to ghost moth herbivory are likely underestimates, because mortality from herbivory was assumed to be the difference in survival between plants in Hepialus suppression and the plants in the control plots.
