Abstract

An alternative to methyl bromide fumigation for controlling stored-productinsects in food processing facilities is to heat part or all of a facilityto 50-60 degreesC for 20-30 h. However, some equipment or structures cannot tolerate these conditions, or it is difficult or expensive to attain these high temperatures. It may be possible to reduce the temperature requirements necessary for effective control by using a desiccating dust, such as diatomaceous earth (DE), in combination with the heat treatment. The objectives of this study were to examine the combined impact of high temperature and DE on the mortality of Tribolium confusum (du Val) in a flour mill environment and to evaluate the effects of DE application rate on insect mortality in a mill environment during heat treatment. In areas of the mill where temperatures were in excess of 47 degreesC, DE applications of 0.3 g/m(2) incombination with heat were no more effective than the heat treatment alone. At higher application rates, the DE was more effective. In cooler areas, adult beetles exposed to DE died sooner than insects not exposed to the insecticidal dust. These results indicate that application of DE in areas thatcannot be heated to 47 degreesC is effective for controlling T. confusum in a flour mill. A comparison is made with a parallel study conducted in Canada. Crown Copyright (C) 2001 Published by Elsevier Science Ltd. All rightsreserved.
