Abstract:

Stored raisins were successfully treated for control of Cadra figulilella (Gregson), Plodia interpunctella (Hübner), Drosophila melanogaster (Meigen), Carpophilus hemipterus (L.), Oryzaephilus mercator (Fauvel), O. surinamensis (L.), and Tribolium castaneum (Herbst) with a low-oxygen atmosphere. The atmosphere, consisting of ≤0.5% oxygen, 10 to 14% carbon dioxide, and a balance mainly of nitrogen, was produced by an exothermic generator that uses natural gas or propane fuel to "burn" oxygen out of the air. This atmosphere was introduced into commercial stacks (bulk storages) of raisins in a continuous-flow, single-pass operation; the atmosphere exiting the stack was not recirculated. Time for purging the raisin stacks to <0.5% O. was ≤48 h, and insect control was obtained in 5 days at 27°C and 14 days at 16°C.
