Predators of plum curculio larvae, Conotrachelus nenuphar Herbst (Coleoptera: Curculionidae), were observed in a peach orchard in middle Georgia. Ants were the only predators that were observed during daylight hours. Solenopsis invicta Buren was the dominant predator of plum curculio larvae, but the pyramid ant, Conomyrma insana (Buckley), was also an important source of mortality. Observations in peach orchards in central Georgia in 1906 revealed that the pyramid ant was the dominant predator of plum curculio larvae at that time.
