New predatory mite provides a strong response to thrips and whitefly
26 October 2011
Koppert Biological Systems is raising the biological control of thrips and whitefly to a higher level with the new predatory mite Amblydromalus limonicus. The company has devoted over ten years to research in the development of this new product. The predatory mite excels in terms of gluttony and reproductive capacity.
Koppert has spent ten years developing Amblydromalus limonicus, and has tested the predatory mite at a large number of firms in the world of practice. It appears to have a number of great strengths.
For example, it is the only predatory mite that also eats larger thrips larvae (phases L1 and L2) and eggs, as well as all larval stages of whitefly. In addition, it has a big appetite and an outstanding reproductive capacity. Moreover, it is active across a broad temperature range, from 13°C to 30°C. In this respect, it surpasses other predatory mites. This combination of unique characteristics therefore makes it ideal for use in a wide variety of crops, including cucumbers, roses and gerberas.
Amblydromalus limonicus is no novice among beneficials. This predatory mite was already well-known as an effective natural enemy of thrips and whitefly. However, it was difficult to produce. That problem has now been resolved. Koppert is planning the first deliveries for early 2012. The company will supply the product in bottles, but the predatory mite can also be dispersed through the crop using a blower. It also tackles spider mite, and can survive on pollen if necessary.
In addition to Swirski-Mite
Koppert intends Amblydromalus limonicus to be used alongside the predatory mite Amblyseius swirskii (Swirski-Mite) and the new product Swirski-Mite LD (with its longer period of effectiveness). In Koppert’s vision, Amblyseius swirskii is the basic natural enemy for thrips and whitefly in many crops. If the level of infestation becomes too high, Amblydromalus limonicus forms the solution.
Koppert will be showcasing this new product at the Horti Fair (stand number 08.0113) and the International Flower Trade Fair (stand number B5.07). Visitors will have the opportunity to submit a name for the product, which will then be officially announced in December. First deliveries are planned for January 2012.
