Sequential sampling to estimate proportion from a binomially distributed population was used to estimate apparent and actual infestation rates of the Nantucket pine tip moth, Rhyacionia frustrana (Comstock), on loblolly, Pinus taeda, and shortleaf pine, P. echinata. Populations of R. frustrana, as measured by infested tips, increased from the overwintering generation through the second generation (July), then decreased rapidly for P. echinata. Populations of R. frustrana continued to increase through the season in P. taeda. Tip moth infestations were concentrated in the top one-half of the tree.
