The current status of research on Solenopsis invicta Buren (Hymenoptera: Formicidae) in Mainland China

Since the Red Imported Fire Ant Solenopsis invicta was found in late 2004 in Mainland China, researchers have paid much attention to this new invasive species. Here we summarise a series of studies on this serious invasive pest, including research on reproductive biology and ecology, ecosystem impacts, quarantine techniques, potential distribution and risk of spread, besides monitoring and management techniques. To date, S. invicta has been found in five provinces in South China and has the potential to spread further north, not only by natural dispersal but also by human transportation. The total S. invicta population increases greatly in spring and autumn, and causes serious ecological impacts because of its high population density in South China Besides quarantine techniques intended to prevent the fire ant from further dispersal, chemical control has been the main management method until a more effective biological control agent is found. In some areas control strategies have achieved promising results.
