According to Holway et al. (2002), six ants are recognized as the most widespread and damaging invasive species: Anoplopepis gracilipes (yellow crazy ant), Linepithelma humile (Argentine ant), Pheidole megacephala (African bigheaded ant), Solenopsis invicta (red imported fi re ant), Solenopsis geminata (tropical fi re ant) and Wasmannia auropunctata (little fi re ant). Wasmannia auropunctata Roger, 1893 is one of the most harmful invasive species in the world (Wetterer & Porter, 2003). Native to Central and South America, W. auropunctata has been introduced throughout the West Indies, Australia, Israel, Italy, Pacifi c islands groups and West Africa (Wetterer, 2013). In Cameroon, W. auropunctata was fi rst reported in cocoa plantations along the Kribi-Ebolowa road (de Miré, 1969). Since then, it has successfully spread into southern and eastern Cameroon (Tindo et al., 2012), where it has severely reduced the abundance and richness of native ant species (Mbenoun et al., 2017). The invasive success of exotic species can vary substantially over time from population explosions to population
