Adults of Keiferia lycopersicella (Walsingham) were monitored with a synthetic sex attractant in a fall planting of fresh market tomatoes to determine the most effective trap type and attractant release rates. Zoecon IC® sticky traps were 6 times more effective in trapping tomato pinworm moths than Delta® sticky traps and mineral oil traps. An inverse relationship existed between attractant release rate (fibers per dispenser) and trapping efficiency in all trap types. Lower release rates (1 and 3 fibers/dispenser) resulted in significantly higher trap catches than higher release rates (10,30, and 100 fibers/dispenser) with a progressive significant reduction in trap catch with each increase in fiber numbers above 3/dispenser. In a further comparison of release rates, 0.5, 1, 3, 5, 7, and 9 fibers/dispenser were compared in Zoecon IC traps. Single fiber dispensers were not significantly different from 0.5- or 3-fiber dispensers, but were significantly more effective than 5, 7, or 9 fibers. Regular renewal of fibers decreased trapping efficiency at the 5 fibers/dispenser release rate.
