Presentation at the International Association of Operative Millers Conference and Expo, Austin, TX, May 20-24, 2006. Technical Abstract: It has long been know that stored-product insects can enter buildings from outside and that sealing off routes of entry is an important part of a pest management program. However, the relative importance of active insect immigration into buildings as a source of infestation compared to importation of infested materials or long-term persistence of the population in the structure has remained unclear. It would be useful for the implementation and interpretation of pest monitoring programs and the selection of the best management tactic to know: what is the level of infestation pressure from outside and how it varies with season and location, what are the sources of these outside pests, and what are their major routes of entry? Recent research findings indicate that insect activity outdoors, and the resulting potential for insects to move from outside sources into buildings, may be greater than previously suspected and have an important influence on the effectiveness of pest management programs. With currently available tools, monitoring programs can be readily implemented to address the above questions for a particular mill.
