Female NPTM Sex Pheromones and Male Response

Abstract--Pheromone traps are used to monitor flight activity of male Nantucket pine tip moths, Rhyacionia frustrana (Comstock), to initialize spray timing models, determine activity periods, or detect population trends. However, a standard-ized trapping procedure has not been developed. The relative efficacies of six types of lures and eight commercial phero-mone traps were compared in field tests in Alabama, Georgia, South Carolina, and Virginia. Additional factors, including trap color, lure longevity and loading rates and ratios were also tested. These tests demonstrate that lures and1 or traps have a pronounced effect on male moth catches. The Pherocon 1Cwing trap was the most effective. White traps were slightly better than colored traps. Pherocon 1C @ wing traps baited with commercial Scent@, EcogenQ or Tr6ckQ lures caught the greatest numbers of moths
