Abstract
Two perfluorinated alcohols, CCRL-489 and CCRL-583, tested as fumigants against stored-product insects, proved to be more toxic than methyl bromide to adults of the confused flour beetle, Tribolium confusum Jacquelin duVal, and the cigarette beetle, Lasioderma serricorne . (F.), and late-stage larvae of the black carpet beetle, Attagenus megatoma (F.), when the insects were exposed in free space. Both compounds were also more toxic than methyl bromide to T. confusum adults exposed in a mass of wheat at 27°C; however both compounds were slightly less toxic than methyl bromide when the temperature was reduced to 13°C. Results of tests in which immature stages of the rice weevil, Sitophilus oryzae (L.), were exposed in a mass of wheat to both perfluorinated alcohols indicated that eggs and early-stage larvae were more tolerant to the alcohols than late-stage larvae, pupae, and adults.
