Koppert launches whitefly biocontrol agent

The Dutch biological control company, Koppert Biological Systems (Berkel en Rodenrijs), has introduced a predatory beetle, Delphastus catalinae, for the control of whiteflies in crops such as gerberas, roses, cucumbers and aubergines. It has been launched under the name Delphibug and combats several whitefly species, the most important being Trialeurodes vaporariorum and Bemisia tabaci. Koppert says that the beetle is unique for its performance under circumstances where other beneficials lose interest. It is applied in situations where whitefly populations get out of control and feeds in “very high quantities”, eating more than 150 eggs daily.
