The Nantucket pine tip moth attacks all pines with two or three needles per bundle except for two of these pines not normally grown in the midwest
Tips of branches die back. Close examination reveals pitch covering the base of the needles. Breaking open the shoot will reveal that the tip has been hollowed out. Annual infestations result in reduced growth and bushiness due to increased lateral bud growth.
This insect usually has several generations per growing season.
Prune out and destroy the dead branch tips. If necessary use a recommended insecticide.
