摘要: ABSTRACT Seven different turfgrass species or mixes used on golf courses in the United States' transitional climatic zone were maintained as randomized and replicated plots separate stands mowed at fairway (1.6 cm) rough (6.4 cutting heights sampled autumn to assess density composition of scarab grubs; incidence disease parasitism thereof; extent turf damage from foraging insectivorous skunks, Mephitis mephitis. Influence grass by spring autumn-active tiphiid wasps was further assessed implanted grubs open enclosures. Masked chafers (Cyclocephala spp.) three-fold more abundant than Japanese beetle, Popillia japonica Newman, Zoysia Cynodon sp. height, P. five-fold masked chafer cool-season height. Phyllophaga spp. accounted for <1% samples. Milky bacteria (Paenibacillus sp.) predo...
