Establishment of a silverleaf whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) population in western Sydney
A field survey in western Sydney found populations of Bemisia tabaci biotype B (silverleaf whitefly) that have the potential to damage greenhouse vegetable crops prevalent in the region. Adult whiteflies were collected from five farms at 2-week intervals and the proportion of silverleaf whitefly in the overall whitefly population was determined using polyacrylamide gel electrophoresis. High levels of silverleaf whitefly were detected at most sampling dates on two of the farms surveyed and a third farm exhibited lower but relatively continuous silverleaf whitefly abundance. The presence of permanent silverleaf whitefly populations must be considered by the greenhouse industry when formulating whitefly management plans for western Sydney.
