Abstract

Oviposition and initial larval feeding (injury) by the Nantucket pine tip moth, Rhyacionia frustrana (Comstock), and the pitch-pine tip moth, R. rigidana (Fernald), were found on neighboring loblolly pine, Pinus taeda L.; shortleaf pine, P. echinata Mill.; longleaf pine, P. palustris Mill.; and slash pine, P. elliottii Engelm. Shoot and bud killing (damage) occurred mostly on shortleaf and loblolly pines. Studies on loblolly and slash pine showed that differential larval survival following oviposition and initial shoot feeding was responsible for differences in shoot and bud killing.
