A state-wide turf grub and soil acidity survey was conducted in Ohio from 1954 through Hl58. These studies indicate that the Japanese beetle, Popillia japonica Newm., increases in numbers more rapidly in low pH soils and that a high grub population continues in these soils year' after year as long as favorable weather prevails during the egg and young larval stage. A similar behavior is indicated for the grubs of the northern masked chafer, Cyclocephala borealis Arrow, whereas the grubs of the .June beetles, Phyllo phaga spp., seem to reach their maximum accumulation at a pH of about 6.0.
