| Abstract/Contents: | "A new entomopathogenic nematode species, Steinernema scarabaei, was evaluated for efficacy against two white grub species, the European chafer, Rhisotrogus majalis, and the Japanese beetle, Popillia japonica, in laboratory, greenhouse, and field trials. In laboratory assays, S. scarabaei caused greater mortality than Heterorhabditis bacteriophora. S. scarabaei was highly virulent with an LC50 of 5.5-6.0 and 5.7 infective juveniles (IJs) per third-instar larva in R. majalis and P. japonica, respectively. In a greenhouse trial, S. scarabaei provided greater mortality of R. majalis at al application rates (0.156-1.25 ^D#x 109 IJs/ha) than Steinernema glaseri and H. bacteriophora (both at 1.25 ^D#x 109 IJs/ha). Combination of imidacloprid and S. scarabaei resulted in an antagonistic interaction. In a fall field trial, S. scarabaei provided 88 and 75% control of R. majalis at 2.5 ^D#x 109 and 109 IJs/ha, respectively, and 54% control of P. japonica at 109 IJs/ha; H. bacteriophora had no effect on mortality of either white grub species. In a spring field trial, unusually cool temperatures impeded nematode activity. Against R. majalis, S. scarabaei provided moderate control (56-59%), whereas Heterorhabditis marelatus provided no control. Mortality of P. japonica was moderate (49-66%) in both S. scarabaei and H. marelatus treatments. Overwinter persistence of S. scarabaei activity was demonstrated in a spring assay of soil from fall treated plots in which nematode infection was absent from control plots and present in treated plots." |
