My role in the department

My role is in research, extension and training within the field of agricultural entomology for broad-scale grain and pasture production. The PestFax service is providing industry with timely information regarding pest and disease threats and management through the newsletter and integrated pest management training courses. We are conducting surveys to document the extent of insecticide resistance in the redlegged earth mite to key insecticide groups. We are investigating critical pest management timing with key invertebrate pests to optimise insecticide efficacy and crop protection efforts. We are also currently studying the spatial distribution of aphids in canola to improve sampling protocols which optimise sampling accuracy and efficiency. I am also involved with use of multi-spectral crop canopy reflectance data acquired from unmanned aerial vehicles to detect potassium deficiency and increased performance of aphids and other arthropod pests.
