The attractiveness of synthetic sex pheromone traps for the cabbage cluster caterpillar, Crocidolomia pavonana (Fabricius)(Syn. C. binotalis)(Lepidoptera: Crambidae) was tested for the first time in the field at the three sites in Java and Bali, Indonesia.In the test with sticky traps, the lure containing a 10:1 mixture of (Z)-11-hexadecenyl acetate (Z11- 16: Ac, 500g) and (Z)-9-tetradecenyl acetate (Z9-14: Ac, 50 ug)attracted significantly more males than those containing the respective single components(500 ug) and black control in Bali and Bogor. This is consistent with the result of the experiment on the same species in a wind tunnel conducted by Usui et al. (Agric Biol. Chem. 51:2191-2195,1987). In Bali, more males were captured by the traps in the broccoli, Brassica oleracea var. italica field than the cabbage, B. oleracea var. capitata field. In the cabbage field planted with the cauliflower as a border crop, significantly lower population of pavinana was observed than in those with the chinese celery, Apium graveolens and the mint, Menta sp. as border crops and than in the field without border crop. A two-choice cage assay suggested that the reduction of the pests on the cabbage accompanied with cauliflower might be due to the females' oviposition preference for cauliflower to cabbage. In the present paper, an integrated pest management strategy for C. pavonana with trap crops, based on the pest population monitoring using the synthetic pheromone traps will be discussed
