Due to a continued complication with the mass rearing of the “zed” mite we have been unable to conduct any more trials. Efforts are ongoing in an attempt to turn this predator culture around.
Lasioseius queenslandicus (ZED) is an Australian native predatory mite of which very little is known. It was originally bred from wild mites on the mid north coast of NSW that had invaded another predatory mite culture. The current culture was re established from collections taken from a rose farm in Melbourne where Lasioseius queenslandicus (Zed) had been previously sent. Bio Works has re established the culture after favourable reports from the rose farm where they had been initially trialled.
Bio Works has been conducting a release trial of the predatory mite Lasioseius queenslandicus (Zed) into a cucumber crop in Coffs Harbour. The aim of the cucumber release trial is to asses the effectiveness of this predatory mite on thrips (Western Flower Thrips). The poly tunnel where it has been released has had a history of thrips problems. Results from the first release in the Autumn crop have been very encouraging. During the winter crop one release was made when the cucumbers were at about 3ft high. However thrips pressure this winter is low due to a combination of cold wet weather and low levels of thrips late in the previous season. More releases will be made moving into the spring and hopefully we will have a better idea of how this predator may be used for Western Flower Thrips management whithin an IPM package.
Lasioseius queenslandicus (Zed) are also being released weekly in a few rose farms, targeting Western Flower Thrips WFT in both tropical and temperate climates.
