Abstract :
We compared the virulence of the entomopathogenic nematodes Steinernema scarabaei, Heterorhabditis zealandica, and Heterorhabditis bacteriophora (GPS11 and TF strains) against third instars of the Japanese beetle, Popillia japonica, the oriental beetle, Anomala (=Exomala) orientalis, the northern masked chafer, Cyclocephala borealis, the European chafer, Rhizotrogus majalis, and the Asiatic garden beetle, Maladera castanea, in laboratory and greenhouse experiments. The virulence of the nematode species relative to each other differed greatly among white grub species. H. bacteriophora and H. zealandica had similar modest virulence to P. japonica, A. orientalis, C. borealis, and M. castanea. But against R. majalis, H. zealandica showed low virulence with a clear concentration response whereas H. bacteriophora caused only erratic and very low mortality. In contrast, S. scarabaei had modest virulence against C. borealis, but was highly virulent against R. majalis, P. japonica, A. orientalis, and M. castanea with R. majalis being the most susceptible and M. castanea the least susceptible.
