[Aim] As a potential strategy for controlling the aphids, the aim was to examine the aphid-trapping effects of Chrysanthemum coronaria grown at different ages and intercropped with Vicia faba in a field.[Method] C. coronaria plants of different growth stages (seedling stage, bud stage, flowering stage) or different ways (one or two rows)were planted in intercropping with V. faba in a field. The rate of infestation of aphids per bean plant and the level of damage were recorded. Each processing is performed in a cell that does not interfere with each other.[Result] The number of aphids per plant and the level of damage were significantly varied among the different ages of the plants. The rates of aphid infestation per plant were reduced to 28.33% for C. coronaria planted at the flowering stage, 41.67% when planted at the bud stage, and 55.00% at the seedling stage, all lower values than the control (63.33%). The percentage of V. faba in each damage level varied among treatments. V. faba plants with flowering C. coronaria showed only 5% rate of infestation at level 5 (highest number of aphids), 23.33% with flower-bud C. coronaria and 33.33% with C. coronaria seedlings while the control had 40.00%. The rate of aphid infestation per plant was 33.33% in one row intercrop, 23.33% in two rows of C. coronaria both significantly lower than the control (66.67%). The proportion of the highest level of damages by aphid for both row designs was significantly lower than that of the control.[Conclusion] The flowering stage of C. coronaria had the most effective trapping effect on aphids living on broad bean. Two rows intercrop of flowering stage C. coronaria can effectively reduce the damage caused by aphids. Intercropping C. coronaria with V. faba could be used as an important ecological control strategy of aphids.
