Twenty-eight sugarcane fields in Florida were sampled for ants using baits or pitfall traps. Using baits, the imported fire ant,Solenopsis invictaBuren, was clearly the dominant ant species being found in the highest percentage of all fields, the highest percentage of all bait cards, the greatest total number caught, and the highest relative abundance. Using pitfall traps,S. invictawas again the dominant ant species being found in the highest percentage of all fields, the highest percentage of all pitfall traps, the greatest total number caught, and the highest relative abundance.S. invictawas first found in Florida sugarcane in 1970. Our data show that since 1970S. invictahas become the dominant ant species in Florida sugarcane resulting in a large reduction in the relative abundance of other ant species.
