Abstract
Diabrotica barberi Smith and Lawrence (the northern corn rootworm) is a native North American leaf beetle and a major pest of corn. However, adult D. barberi forage in various habitats outside of corn fields, including soybean, roadside vegetation, and prairie. Eugenol is a common floral volatile that has been shown to increase trap catch of D. barberi within corn and prairie habitat. This paper documents the first report of increased catch of D. barberi on eugenol- baited traps in soybean fields. In two successive tests, catch of D. barberi was increased eight-fold or more by baiting traps with eugenol compared to ethanol-baited control traps. The attraction of D. barberi to eugenol-baited traps in soybean expands the potential for using such traps in determining the landscape-wide spatial and temporal dynamics of this beetle. Diabrotica
