Interpretive Summary: In the Northeastern United States, the Japanese beetle has been considered the key turfgrass insect pest even though a significant amount of the damage attributed to is it actually caused by the oriental beetle. The oriental beetle is also the major pest in ornamental nurseries and blueberries, and causes losses in cranberries, strawberries, raspberries, peaches, and sweet potatoes. The extensive feeding activity of the large grubs can kill the grass and plants. Until today, chemical insecticides are still the primary tools for turfgrass insect pest management. The need for the development of safer effective alternatives is apparent. Using insect attractants, sex pheromones, to disrupt the mate finding is widely used as an environmentally safe, non-toxic alternative to broad-spectrum insecticides for several moth species. We initiated a study to determine the feasibility of such technology to control the oriental beetle. The present study demonstrated that this technology is feasible in the turfgrass system. The effect of the sex attractant could significantly reduce in grubs and adult oriental beetle populations in the treated areas. However, we found that the efficacy and feasibility of this technology could be improved with different forms of the insect attractant tested. Also, contamination of shoes and other clothing articles with insect attractant in the tested golf course could attract male beetles to these articles outside of treated areas, and therefore present a potential nuisance. Our future efforts will concentrate on the development new forms of attractant, which could make this technology more effective, safe, environmentally and economically sound, easily implementable, durable, and highly integrated pest management compatible option for ornamental plant and turfgrass managers in oriental beetle management.
