Abstract

Control of the imported fire ant, Solenopsis saevissima richteri (Forel), with two applications of heptachlor at dosages of 1/4 or 1/2 pound per acre applied at intervals of 3 or 6 months was reported by Lofgren et al. (1961). Murphy et al. (1962) reported that soil residue following two successive 1/4 pound per acre treatments of heptachlor is equivalent after 10 months to the residue following a single 1 pound per acre treatment.
