Koppert presents new biocontrol agents

Dutch bioproducts company Koppert Biological Systems (Berkel en Rodenrijs) has developed a new biological control product for thrips and whiteflies using the predatory mite, Amblydromalus limonicus.. It is the only predatory mite that eats larger thrips larvae (phases L1 and L2) and eggs, as well as all larval stages of whiteflies, Koppert says. A limonicus also surpasses other predatory mites in being active across a broad temperature range from 13°C to 30°C. Koppert says that A limonicus is known as an effective, but difficult-to-produce, natural enemy of thrips and whiteflies. It has resolved the production problem and plans deliveries for early 2012. The company has also produced a variant of its Amblyseius swirskii predatory mite-based product. Swirski-Mite LD (Long Duration) remains present in the crop for longer as it releases mites over a longer period. That makes it ideally suited to a preventative approach.
