【Background】One of important problems in invasion biology is the influence of an invader on the biodiversity and its relationship with the native species in the invaded area. To reveal the interaction between the invasive red fire ant (Solenopsis invicta) and the native ant species with similar niche is important for understanding the ecological effects of the fire ant invasion. 【Method】Interference competition between the short-term invasive S.invicta and native ant Tapinoma melanocephalum in wasteland and a lychee orchard were investigated by recording the change of T.melanocephalum worker numbers, which recruited on bait placed near the two ants′ nests. 【Result】The number of T.melanocephalum workers recruited on bait was more influenced by S.invicta in wasteland than in a lychee orchard. In un-infested wasteland, T.melanocephalum workers did not return to the bait when we removed S.invicta workers from the bait, even after 20 min. Such interference was much lower in the lychee orchard: 5 minutes after the S.invicta workers were remvoed from the bait, the T.melanocephalum worker numbers surpassed the pre-invasive numbers. 【Conclusion and significance】Interference and inhibition on the foraging behavior of T.melanocephalum workers after the fire ant invasion were significant, and the negative impact was closely related to the complexity of the habitats. These results provided the scientific evidence for understanding the ecological effects of the fire ant invasion.
