Abstract/Contents: | "Researchers at the University of Kentucky investigated how effective two wasp species can be as a biological control of white grubs. Their findings include: Tiphia pygidialis and Tiphia vernalis were found to be abundant on Kentucky golf courses. Pan traps and dilute sugar sprays were used to monitor seasonal flight periods of both wasp species. Sugar sprays applied to tree foliage was ineffective for monitoring T. pygidialis, but sugar water sprayed directly on the turf attracted large numbers of that species. Parasitism rates ranged from 15-50% at the study sites. Each wasp species can discriminate between body odor trails and frass from host and non-host grubs to find their specific target grubs. Once parasitized grubs cease feeding on turfgrass roots and move deeper into the soil. Wildflower gardens planted near the turf sites were ineffective in attracting Tiphia wasps. Field and lab studies suggested that applications of imiacloprid [imidacloprid] (Merit) insecticide adversely affected the wasps' ability to locate grubs." |
