Abstract
The oral toxicity of boric acid to the Florida carpenter ant, Camponot us abdominalis floridanus (Buckley), was evaluated in laboratory tests . The ants were provided a sucrose water-based bait containing various concentrations of boric acid. Over the dosage range from 0.02 M (0.13 % w/v) to 0.50 M (3.13% w/v) boric acid, median lethal times (LT(50)s) (95% CL) ranged from 9.7 (8.1-13.3) days to 1.5 (1.2-1.7) days. Over the same dosage range (0.02 M to 0.50 M), LT(90)s (95% CL) ranged hem 27.1 (18.0-59.5) days to 4.2 (3.6-5.1) days. Some of the advantages of using boric acid as a bait toxicant for ants include its delayed acti vity and its solubility in water.
