The abundance and occurrence of predatory heteropterans including Geocoridae, Miridae, Nabidae and Anthocoridae were studied in residential turf in Georgia. Abundance of these predatory bugs was related to abundance of other potential prey such as Sminthuridae, Isotomidae and Entomobryidae. Samples were collected between 11 am to 4 pm to ensure maximum insect activity. Factors affecting occurrence and abundance included different turfgrass types and other parameters such as grass thickness, height, weed density and level of management. The majority of turfgrass species were bermudagrass, St. Augustine grass, centipedegrass, zoysiagrass and tall fescue.
