Laboratory studies of Chrysoperla carnea predation on Bemisia tabaci

Common green lacewing, Chrysoperla carnea (Stephens), larvae consumed all immature stages of the sweetpotato whitefly, Bemisia tabaci (Gennadius). First stage lacewing larvae consumed sweetpotato whitefly eggs and larvae in about the same time, and second stage lacewing larvae consumed B. tabaci eggs more rapidly than did first stage lacewing larvae. Third stage lacewing larvae consumed whitefly pupae in 33 to 78 seconds. Sweetpotato whitefly adults avoided cotton leaves when lacewing larvae were present and for several days after lacewing larvae were gone.
