Abstract
Feeding preferences of Japanese beetle, Popillia japonica Newman, and southern masked chafer, Cyclocephala lurida Bland, grubs for six common cool-season turfgrasses were evaluated in choice tests in the greenhouse. On the basis of larval distributions, Popillia japonica consistently preferred perennial ryegrass, Lolium perenne L., over all other turfgrasses tested. In contrast, C. lurida showed no consistent pattern of preference. Presence of one grub species did not affect distribution of the other species. Grubs did not discriminate between tall fescue, Festuca arundinacea Schreb., infected with the endophyte Acremonium coenophialum Morgan-Jones & Gams and endophyte-free tall fescue.
