Abstract

Laboratory comparisons of sulfuryl fluoride toxicity and mean time of mortality among ten termite species (Isoptera: Hodotermitidae, Kalotermitidae, Rhinotermitidae).

Abstract

Ten termite species representing 3 families were fumigated with sulfuryl fluoride for 22 h in the laboratory. Reticulitermes flavipes and R. tibialis were most sensitive (LAD50 (lethal accumulated dose) = 13.42 and 14.52 mg.h/litre, respectively), and Incisitermes minor was the least sensitive (LAD50 = 30.36 mg.h/litre). The greatest and least post fumigation grand mean time of mortality was 3.11 and 1.58 days for R. tibialis and I. snyderi, respectively. Zootermopsis angusticollis had a uniquely steep probit-mortality slope.
