Field-collected Scaphytopius spp. adults were marked with fluorescent pigment, released in a cultivated blueberry (Vaccinium corymbosum L.) field and an adjacent wooded site in Bladen Lakes State Forest, NC, and recaptured on yellow sticky traps. Of those S. magdalensis (Provancher) released in the wooded site, 17.3, 27.1 and 43.7% were recaptured in the wooded area during generations I-III, respectively. Of those S. magdalensis released in the cultivated field, recapture in the same field was 11.5 and 27.9% during the first two generations, but only 1.5% at the beginning of the 3rd generation. Adults apparently moved out of the wild habitat during the 1st generation and out of cultivated fields during the 3rd. This movement pattern was not found in S. verecundus (Van Duzee). First-generation S. magdalensis should be controlled during their flight into cultivated fields.
