Density changes of two earwigs, Labidura riparia (Pallas) and Euborellia annulipes (Lucas) following fire ant reduction in Mumford, Texas Academic Article uri icon


  • Solenopsis invicta Buren disrupts arthropod diversity by aggressively displacing other species either by direct or indirect competition. We observed the effect of S. invicta reduction with baits on natural populations of earwigs, Labidura riparia (Pallas) and Euborellia annulipes (Lucas) in Mumford, Texas. Reduction of fire ants was followed by significant increases of these two species' densities, indicating they were released from competition pressures or predation by S. invicta.
