Population of the cigarette beetle was monitored by traps baited with a synthetic sex pheromone (serricornin, 4, 6-dimethyl-7-hydroxynonan-3-one) and food attractant (extract of herb) in 16 factories of hand-extended fine noodles. The beetles were found in all factories tested and a few drug-store beetles (Stegobium paniceum L.) were also detected in traps of 9 factories. The cigarette beetles were caught from May to Nov. and at least four peaks of population outbreaks were observed; from May to Jun., late Jun., late Aug. and early Oct.. Although the beetles were trapped at all places in a factory, surroundings of wheat flour, products and trash, corners of rooms and crevices of floors were the most probable sites of adult emergence.
