Predators attracted to the sex pheromones of Matsucoccus josephi, M. feytaudi, M. matumurae, and controls (without pheromones ) in east Tennessee were collected from May 1999 through July 2000. Delta style sticky traps (n=60) baited with the sex pheromones were placed in 5 pine sites along elevation gradients in the Great Smoky Mountains National Park . From 468 sticky inserts processed, 7,972 insect specimens representing 112 species, 83 families, and 12 orders were identified. Highest number of predators collected included the neuropterans Hemerobius stigma Stephens (=stigmaterus Fitch), Sympherobius barberi Banks, and Micromus posticus Walker, and the hemipteran Elatophilus inimica D&H. Sex pheromone traps of M. josephi captured the highest number of individuals (267) compared to M. feytaudi (224), M. matsumurae (25), and the control (1). Significantly high numbers of predators were captured at pine sites in traps baited with pheromones of M. feytaudi and M. josephi in stands of Pinus pungens on rocky ridges between 914m and 1392m. Collection of E. intimica represents new county and state records, and the southern-most distribution recorded for this species.
