Mortality of adult Rhyzopertha dominica (F.), Sitophilus oryzae (L.) and Triboliumcastaneum (Herbst) was recorded after exposure for different times to application rates of 0, 0.5, 1, 1.5 or 2 g/m2 of the diatomaceous earth (DE) DEBBM-P/WP and to 0, 3, 4, 5 or 6 g/m2 of the DE Protect-It®. Mortality of all insects increased with increasing exposure interval; dry dusts were more effective than slurries, and overall mortality was greater for DEBBM-P/WP than Protect-It®.
