The adult population fluctuations of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) in flour factories in Bursa province This study was carried out to determine adult population fluctuations of Mediterranean flour moth, Ephestia kuehnilella Zeller by means of pheromone traps in total 7 flour factories in Osmangazi, Nilüfer, Karacabey, Yenişehir districts of Bursa province during 2000-2002. In monitoring of the adult E.kuehniella population fluctuation and catching of adult in traps studies, Pherocon II type trap, IMM+4 (sex pheromone of Plodia interpunctella Hübn.) pheromone capsule were used and the number of the adults caught in traps evaluated weekly. As a result of these studies, the first E. kuehniella adults were observed on April; on the other hand the adult flights decreased after October and E.kuehniella showed 2-4 distinct flight peaks in the flour factories. It was determined that adult flight of E. kuehniella usually become dense in the machine part of flour factories. Consequently, pheromone traps were effective in determining the adult emergence and pest densities in storage houses and thus they could be an important aid in appropriate timing of insecticide applications, which could result in fewer applications of insecticide for managing stored product pests
