Laboratory fumigations were conducted to compare the toxicity of 1,2,3-tribromopropene (C2H3Br3), ethylenimine (C2H5N), crotyl bromide (86% 1-bromo-2-butene and 14% 3-bromo-1-butene), and carbon tetrachloride (CCI4), to the adult confused flour beetle, Tribolium confusum Jacquelin du Val; to the adult saw-toothed grain beetle, Oryzaephilus surinamensis (L); to the adult cigarette beetle, Lasioderma serricorne (F.); and to the black carpet beetle larva, Attagenus piceus (Olivier). The insects were fumigated with these chemicals in 19-5-liter bottles for 24 hours at 80 ± 4° F and at an RH of 78% ± 18%.

The dosage (mg/l) required for the LD95, depending on the species, varied from 0.35 to 2.39 for 1,2,3-tribromopropene, 0.87 to 5.02 for ethylenimine, 1.49 to 6.15 for crotyl bromide, and 50.7 to 298.1 for carbon tetrachloride.
