Greenhouse trials were conducted to determine the dispersal distance and attractiveness of different plant stages of potted chrysanthemum plants to western flower thrips. Adult thrips were found to be significantly more attracted over 4, 8 and 12 m distances to flowering plants versus plants in the bud and cracking stages. Greenhouse cage trials at a plant density of 49 plants per cage and a density of 0, 1, 2 or 3 flowering plants per cage are currently being conducted to determine the density of trap plants required to effectively attract adult thrips from the host crop. The next step will be to combine control different control strategies with the trap plant to develop a cost-effective IPM program for western flower thrips on greenhouse potted chrysanthemums.
