Many floricultural growers are extremely interested in utilizing biological control and many already use natural enemies for control of leafminers, spider mites, thrips and greenhouse and silverleaf whiteflies. Prior to the implementation of integrated pest management (IPM) in these greenhouses, iris whitefly (Aleyrodes spiroeoides) and citrus mealybug (Planococcus citri) were considered minor pests of floricultural crops. However, as a result of decreased pesticide applications to floriculture crops, iris whitefly and citrus mealybug populations, previously controlled by pesticides, are rebounding and becoming major floricultural pests, highlighting the consequences that may occur as a result of decreased chemical applications.
