Technical Abstract: The predatory activities of commercially-purchased Hippodamia convergens Guèrin-Mèneville and two laboratory-reared strains of Geocoris punctipes (Say) were compared with their feral counterparts. In single prey choice feeding tests, commercially-purchased and feral H. convergens were provided copious amounts of sweetpotato whitefly, Bemisia argentifolli Bellows & Perring, adults or eggs of pink bollworm, Pectinophora gossypiella (Saunders). Commercially-purchased H. convergens devoured more pink bollworm eggs at a faster rate; however, feral H. convergens consumed more adult whiteflies at a faster rate. In multiple feeding choice tests, two laboratory-reared strains and feral G. punctipes were provided a cotton leaf disk containing copious amounts of sweetpotato whitefly eggs, nymphs, and adults. Virtually no predation was observed on whitefly eggs, but both laboratory strains of G. punctipes fed more often on whitefly nymphs and adults. Moreover, both of the laboratory strains had a significantly faster feeding rate on adult whiteflies and spent significantly less time feeding on plant tissue. These results suggest that these augmentative biological control candidates retained their ability to prey on these selected prey items, even after being displaced from their overwintering site or being reared in captivity for over 40 generations.
