This Quickscan was conducted after the interception of the fig white fly species Singhiella simplex on Ficus plants originating from Costa Rica. The species is a serious pest of ornamental Ficus plants but is not known as a pest of Ficus carica that is grown for its fruit. The pest is especially a risk for Ficus plants grown outdoors in southern Europe. The species appear to spread over the world probably as a consequence of trade as it has been reported from several continents outside its native origin. It has recently been found in the EU (on Cyprus) and no statutory action was taken against it. In glasshouses in northern Europe, the species may be controlled and even eradicated by application of insecticides.
