Catangui, Billy W. Fuller, Arnie W. Walz, Mark A. Boetel, Mark A. Brinkman] Abundance of ants on mixed-grass rangelands was not significantly reduced by aerial applications of Dimilin 2 F, Dimilin 25 W, and Sevin 4-0il. Ant diversity, measured by a probability of interspecific encounter index, temporarily declined in plots treated with Dimilin 25 W from 13 to 19 d after treatment. However, diversity immediately recovered the following week and no further declines were observed even at 349-356 d after treatment. Twenty species of ants were encountered at the experimental site. Lasius neoniger Emery; little black ant, Monomorium minimum (Buckley);thief ant, Solenopsis molesta (Say);odorous house ant, Tapinoma sessile (Say);and Formica neogagates Emery were the 5 most abundant species at 25.8, 20.1, 9.9, 7.6, and 7.5% of the total number of ants encountered, respectively. Spatial distribution of ant species on rangeland appeared to be soil related. Factor analysis of soil parameters (weighted for relative ant abundances) indicated associations between ant species and certain combinations of soil properties. © 1996 Entomological Society of America Population Ecology nationallicence ants nationallicence mixed-grass rangeland nationallicence diflubenzuron nationallicence Catangui Michael A.
