 Notes
Abstract: Studies were conducted to develop a toxic bait to control the imported fire ant, Solenopsis saevissima richteri Forel. The investigations were designed to find effective, inexpensive food attractants and delayed action toxicants that permit distribution of the bait in the colony before the worker ants are killed. A search was also made for granular carriers for the food attractants and toxicants that would carry the bait through vegetation to the ground where the ants forage. Vegetable oils with iodine values of about 100 and saturated animal fats such as lard and tallow were the most attractive food materials found. In addition, they are good solvents for the toxicants, relatively inexpensive and readily available. Highly unsaturated vegetable oils are unattractive. Rancidity and hydrogenation cause a decrease in the acceptance of vegetable oils. The most effective toxicant found was mirex. It gave delayed kill (less than I5/0 mortality after 2^^- hours but at least SO'jo after 2 to 20 days) over a k)0-fold range of concentrations (0.0025-1.0-;^). In a bait transfer test in which large worker ants transferred bait to equal numbers of minor workers, it gave kill of the minor workers over a 10- fold range of concentrations. It was the only toxicant that gave kill of major workers when baits were transferred to them by minor workers. Although not highly absorptive, the most useful and practical carrier was corncob grits. Mineral carriers such as attapulgite clay react with food oils, causing them to set-up or harden. The best bait formulation tested consisted of corncob grits (85;;^) impregnated with soybean oil containing mirex at concentrations of 0.075^ to 0.3^. It gave excellent control of ants in small plot tests. It is readily applied with various types of granular application equipment and is easily packaged and stored. Aerial application of this bait at the rate of 12 l/2 pounds per acre to a 960-acre plot gave over 99^0 control of ant colonies. The bait is now used routinely in the Imported Fire Ant Eradication Program.
