The tobacco moth, Ephestia elutella (Lepidoptera: Pyralidae), is a serious pest of stored tobacco. The species has the female-produced sex pheromone. The pheromone components were identified as (Z,E)-9,12-tetradecadien-1-ol acetate (ZETA), and (Z,E)-9,12-tetradecadien-1-ol (ZETOH) by Brady and Nordlund (1971) and Kuwahara et al . (1973). Based on their findings, pheromone traps with these components have been developed and used to monitor the species. The Indian meal moth, Plodia interpunctella , the almond moth, Cadra ( Ephestia ) cautella , and the Mediterranean flour moth, Ephestia ( Anagasta ) kuehniella, belong to the pyralidae family like the tobacco moth. The former three species are pests of mills and food-processing plants and do not feed on cured tobacco. They also have the female sex pheromones and the four species share two components, ZETA and ZETOH. Consequently, when the four species inhabit the same place, they are caught by a pheromone trap with the same pheromone components.In the present study, we clarified the attractiveness of a tobacco moth lure (GACHON) with ZETA and ZETHO for three pyralid moth species in a laboratory. Attractiveness was the highest for the tobacco moth. Ratios of attractiveness for the other three species to attractiveness for the tobacco moth were 0.32 ( P. interpunctella ), 0.15 ( C. cautella ) and 0.24 (E . kuehniella ). In conclusion, the tobacco moth lure attracted four pyralid moths. However, most of the pyralid moths caught by the pheromone trap were the tobacco moths.
