Abstract: Field trials were conducted from May to November, 2010 to assess whether thecommercial Allure MD pheromone dispensers can disrupt development of Ephestia spp. andPlodia interpunctella (Hübner) (Lepidoptera: Pyralidae) under practical in three flour mills and aflat bulk grain storage in Germany. The monitoring traps in the untreated control caught on anaverage six moths more than the ones in one flour mill (in two weeks) where catches remainedbelow one moth per trap during the entire observation period. In the untreated grain store, mothcatches went up to 200 after five weeks per trap and week while there were none to one in thetreated area. The other two mills did not show any influence of the treatment on mothpopulations.
