Methyl Bromide Alternatives and Emissions Research Conference Proceedings, Orlando, FL, November 6-9, 2006. Technical Abstract: Pest management professionals commonly utilize aerosolized liquid applications, also known as fogging, for management of stored-product insects, including the red flour beetle. These applications are part of a potential methyl bromide replacement technology because they could increase the time interval between structural fumigations or heat treatments. This study was conducted in pilot-scale warehouses to investigate the influence of spilled food accumulation, exposure under pallets vs. in the open, and different insect life stages on red flour beetle mortality using two common insecticides (esfenvalerate and synergized pyrethrins). Data show that aerosolized insecticide applications provided the greatest red flour beetle mortality in empty dishes placed in the open. Observed mortality decreased with increasing food accumulation in the dishes and exposure under pallets.
