Abstract

From 1975–78, subcolonization releases were made of the originally Paleartic Coccinella septempunctata L. at 7 sites in 4 Oklahoma counties. Recoveries of C. septempunctata in Payne and Lincoln Counties are summarized for 1976–78 with no recoveries following releases in the other 2 counties. After introduction into Payne County, Oklahoma in 1975, the predator has survived 3 years and spread at least 5 km. Nine aphid species were found associated with recoveries of C. septempunctata . The three most common were Acyrthosiphon pisum (Harris), Therioaphis maculata (Buckton), and Dactynotus ambrosiae (Thomas).
