Jh. Klotz et Ji. Moss, ORAL TOXICITY OF A BORIC-ACID - SUCROSE WATER BAIT TO FLORIDA CARPENTER ANTS (HYMENOPTERA, FORMICIDAE), Journal of entomological science, 31(1), 1996, pp. 9-12
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.
