Koppert Biological Systems is offering a new soil dwelling predatory mite, Macrocheles robustulus, for thrips control. Marketed as Macro-Mite, M. robustulus is a relatively large soil-dwelling predatory mite with a large and diverse appetite. It is very effective against thrips pupae and also feeds on mosquito and fly larvae and the eggs and young caterpillars of Duponchelia. M. robustulus can establish a large population much more quickly than Hypoaspis species so it has a shorter response time to start control.
