EXPERIMENTAL INCIPIENT NEST TRANSPLANTS AND SURVIVORSHIP OF SOLENOPSIS-INVICTA BUREN (HYM, FORMICIDAE) IN BRAZIL

Abstract

Transplants of incipient colonies of the fire ant, Solenopsis invicta into areas in which mature colonies had been eliminated did not result in higher rates of success than in areas in which mature colonies were present. However for both types of sites, Pogonomyrmex (Ephebomyrmex) nagelli colonies were found in cleared sites used for transplants, with the number of translocated P. nagelli nests higher in areas which had not been treated with Mirex for S. invicta colony reduction. These results suggest that small colonies may be displaced by larger colonies of other species.
