Abstract
Ten termite species representing three families [ Zootermopsis angusticollis (Hagen), Hodotermitidae; Cryptotermes cavifrons Banks, Incisitermes minor (Hagen), Incisitermes snyderi (Light), Neotermes jouteli (Banks), Kalotermes approximatus Snyder, Kalotermitidae; Coptotermes formosanus Shiraki, Reticulitermes tibialis Banks, Reticulitermes flavipes (Kollar), and Prorhinotermes simplex (Hagen), Rhinotermitidae] were fumigated with sulfuryl fluoride for 22 h in the laboratory. R. flavipes and R. tibialis were most sensitive (LAD30 = 13.42 and 14.52 mg-h/liter, respectively), and I. minor was least sensitive (LAD50 = 30.36 mg-h/liter). Greatest and least postfumigation grand mean time of mortality (±SEM) was 3.11 ± 0.04 and 1.58 ± 0.05 d for R. tibialis and I. snyderi , respectively. Z. angusticollis had a uniquely steep probit-mortality slope.
