Kairomones can potentially be used for attracting insects to insecticide-treated areas within a field. Synthetic kairomone blend, based on the volatiles produced by potato plants, has been recently demonstrated to be attractive to both adult and larval stages of the Colorado potato beetle. We conducted extensive screening of different commercially available chemical compounds in order to develop an attracticide blend to be used in potato fields. Regardless of which insecticide was used, addition of the kairomone had a significant negative effect on the densities of all Colorado potato beetle life stages except egg masses. This confirmed that kairomone shows promise in enhancing insecticide-induced mortality in the Colorado potato beetle.
