Six foraging and four recruitment parameters were examined and compared among the exotic Solenopsis invicta Buren and the native Texas ants Pheidole dentata Mayr, Forelius foetidus (Buckley), and Monomorium minimum (Buckley). Assays were conducted in the laboratory with interspecific interactions excluded. Two of the three native species, F. foetidus and P. dentata, were superior in overall foraging ability compared to S. invicta when the number of individuals per colony was equal. The foraging strategies utilized by these four species are elucidated and discussed from a time-efficiency and interaction perspective for each of the six foraging parameters. A unique myrmicary design for maintaining ants while studying their particular foraging strategies is also described.
