DescriptionNonlethal damage to female flowers of slash pine (Pinus elliottii Engelm.) by a thrips, Gnophothrips fuscus Morgan, was examined a Florida seed orchard. Thrips-damaged flowers developed into crooked mature cones with areas of sunken, deformed cone scales. Damaged cones were significantly shorter, yielded fewer total seed and filled seed per cone, and opened more poorly than undamaged cones.
