Thelohania solenopsae Knell, Alan, and Hazard is an internal microsporidian that parasitizes the red imported fire ant, Solenopsis invicta Buren. This experiment studied interactions between Monomorium minimum (Buckley), and S. invicta colonies infected with T. solenopsae. This study utilized S. invicta colonies of 100, 300, 600, 800, and 1000 workers to determine the ability of 1000 M. minimum workers to invade RIFA colonies. There was a significant difference in the time for M. minimum to invade S. invicta colonies infected with T. solenopsae as compared to uninfected colonies.


Species 1: Hymenoptera Formicidae Monomorium minimum (Little Black Ant)
