Factors improving the attractivenness of traps baited with the synthetic sex attractant of Chilo suppressalis, i.e., appropriate mixture of Z-11-hexadecenal (HDAL) and Z-13-octadecenal (ODAL), were examined in teh field. Both rubber septa and polythylene capsules were good dispensers for loading of teh chemicals because they retained attractiveness for a long period. The amount of the attractant loaded on rubber dispensers was shown to be a critical factor. Attraction was shown by the dispensers loaded with 0.1-10mg of the attractant. Two mg was the best dispenser, having caught about 64% of the catch of virgin female traps. The ratio of the two pheromonal components was not so critical for attraction. Attractiveness was revealed by the mixutures rangeing in ratios from 20 : 1 to 1 : 1 (HDAL : ODAL). Among these, 3 : 1, 5 : 1 and 7 : 1 were more attractive than other mixtures.
