Citation: ARTHUR, F.H. OPTIMIZATION OF INERT DUSTS USED AS GRAIN PROTECTANTS AND RESIDUAL SURFACE TREATMENTS. STORED PRODUCTS PROTECTION INTERNATIONAL WORKING CONFERENCE PROCEEDINGS. 2003. pp. 629-634. Technical Abstract: Inert dusts such as diatomaceous earth (DE) are being advocated as natural control methods to eliminate insect infestations in stored grain, milling and processing plants, and food storage areas. However, efficacy of DE can be quite variable, depending on the specific formulation of DE, the particular insect species and life stages used in tests, methods of exposure, environmental conditions, or presence of food material. It is important to identify sources of variation so that controlled laboratory studies are relevant to actual exposure conditions in field situations. Examples will be used to illustrate concepts and ideas for inert dusts used as grain protectants and as residual surface treatments in indoor areas. New research approaches will also be discussed in which inert dusts are used in combination with other insecticides to control stored-product insects.
