Tiphiid wasps are used as biological controls of white grubs in farm settings (Davis 1919) and as a turfgrass pest management strategy (Rogers and Potter 2004). Female wasps seek out beetle larvae in the ground. The female deposits an egg on the body of the grub. As the wasp larvae develop, they eat the beetle larvae. Biological controls such as this occur in nature, but as the populations of both species fluctuate, the level of parasitism changes from season to season.
