A method for year-round rearing of hoverflies was developed at TARI. Thus, Hoverflies can be released year-round as pollinator for production of crops, such as cabbages, strawberries, melons, and fruit trees. In addition, the offspring of these reared adult syrphid flies used act as effective predators on aphids feeding on the crops.

    Traditionally, eggs of the Rice Moth Corcyra cephalonica have been used as a food source for the mass rearing of green lacewings, but this has proven expensive. To reduce production costs, TARI developed a technique using artificial eggs in microcapsules to replace Corcyra cephalonica eggs as a food source for mass rearing green lacewings. This technique, accompanied by improvements in storage and delivery methods, means that green lacewings can be produced for practical application in the field as biocontrol agents of a wide variety of soft-bodied insect pests.
