Monitoring traps baited with lepidopteran sex pheromones and synthetic floral volatiles were used to collect adult Hymenoptera in fields of cotton and corn. Species from Apoidea, Pompiloidea, Scolioidea, Sphecoidea, and Vespoidea were collected, including the genera Ammophila, Apis, Bombus, Cerceris, Larra, Melissodes, Myzinum, and Tachytes. More Bombus spp. were collected from traps baited with Spodoptera frugiperda (J. E. Smith) sex pheromone than those baited with phenylacetaldehyde, whereas more Sphecoidea were collected in phenylacetaldehyde-baited traps. Trap design was also an important factor in capture of various species. More Sphecoidea and Tiphioidea were collected in fabric cone-shaped traps than plastic funnel traps. Efforts should be made to develop traps and lures that consistently capture the target pest but do not attract or easily capture aculeate Hymenoptera to preserve beneficial populations.
