Barrier screens reduce damage from brown marmorated stink bug

Barrier screens with different mesh sizes were evaluated for their ability to exclude the brown marmorated stink bug, provide entry to beneficial species, and produce high marketable yield in organically grown bell peppers. Fine-mesh plots were determined to effectively exclude insects and reduce stink bug injury on peppers. For areas with smaller stink bug populations, lighter colored, and/or wider meshes were recommended, while finer meshes were found appropriate for areas with higher stink bug pressure.
