An enhanced mixture of diatomaceous earth (DE) with the plant extract bitterbarkomycin (BBM) was evaluated in the laboratory against adults of three major stored-product pest species. This mixture (DEBBM) was applied at three dose levels; 50 ppm, 100

BACKGROUND: The use of diatomaceous earths (DEs) provides a promising alternative to the use of contact insecticides in stored-product IPM. Geographical origin and the physical properties of a given DE may affect its insecticidal activity. In the pre

The insecticidal effect of bitterbarkomycin (BBM), a plant extract from the roots of the plant Celastrus angulatus, was evaluated as a stored-grain protectant when used either alone or in combination with diatomaceous earth (DE). Bioassays were carri

Laboratory selection experiments were undertaken in order for the resistance development of Tribolium confusum adults to diatomaceous earth (DE) to be assessed. Adults from an initial laboratory reared population (P) were selected by exposure on hard

Laboratory bioassays were conducted to evaluate the susceptibility of seven populations (strains) of the confused flour beetle, Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae), to five commercially available diatomaceous earth (DE) fo
