Abstract

After the phase out of methyl bromide and dichlorvos (DDVP) the disinfestation of flour mills is in a difficult position in the European Union. Sulfuryl fluoride (ProFume®) is registered in France for the disinfestation of empty premises since 2006. The cost of a fumigation is very high, that’s why the aim of this study is to assess the effectiveness of fumigations at low concentrations of sulfuryl fluoride on eggs (the most tolerant stage) of the two mains flour mills pests: Tribolium confusum Jacquelin du Val and Tribolium castaneum (Herbst). Four mills were fumigated with different concentrations, for an exposure time of 21 to 39 hours with, in five levels of each mill, two 20 litres plastic drums containing flour wheat infested by eggs of T. castaneum in the first drum and eggs of T. confusum in the second. The two controls, containing eggs of these two species of Tenebrionidae, were placed in the same conditions but without undergoing the fumigation.
