| Abstract/Contents: | "White grubs (Coleoptera: Scarabaeidae) are susceptible to entomopathogenic nematodes of the genera Steinernema spp. (Rhabditida: Steinernematidae) and Heterorhabditis bacteriophora (Nematoda: Heterorhabditidae). In Germany, primary damages to turfgrass are caused by the herbivorous root-chewing larvae of Amphimallon solstitialis and Phyllopertha horticola and by Melolontha melolontha to many highly valuable crops (e.g. asparagus, strawberry, apple trees). Tremendous secondary damages to turfgrass is caused by grub feeding predators such as crows, foxes, and wild boars. Although reliable biological control of populations of P. horticola can be achieved with H. bacteriophora, beetles with perennial life-cycles such as A. solstitialis and M. melolontha were less or non susceptible. Recently several North American white grubs species were found highly susceptible to S. scarabaei, isolated in central New Jersey. Field collected third-instar larvae of P. horticola, A. solstitialis and M. melolontha were tested individually for their susceptibility against S. scarabaei. Five different infective juvenile (IJ) concentrations (5 - 400 IJ) of S. scarabaei (J3) were applied. Twenty-five grubs per IJ concentration were kept individually in 50 ml cups with 30cc soil and grass seedlings. The assay cups were incubated at 20°C in growth chambers and mortality of the grubs was determined after 14 days. All tested white grubs species were highly susceptible to S. scarabaei (M. melolontha: LD50/90 = 39/173IJs/grub; A. solstitialis: LD50/90 = 9/64IJs/grub). In contrast, at 400 H. bacteriophora IJs/grub the mortality remained below 20%. Also the grubs of P. horticola are more susceptible to S. scarabaei." |
