For the cut flower industry, the results indicate that T. montdorensis and N. cucumeris are N. cucumerithe most effective commercially available predators that provide control of western flower thrips (WFT) in Australia. Orius armatus shows promise for the cut flower industry; however, further research is required to determine its efficacy compared with T. montdorensis and N. cucumeris. Soil biological control agents are unlikely to be cost-effective, except perhaps at moderate thrips pressure, on gerberas, chrysanthemums and roses as they did not appreciably reduce the numbers of WFT on foliage or flowers.
