Dr Bedding has pioneered and led the world in obtaining new basic information on the taxonomy, biology, physiology and ecology of nematodes which has enabled him to develop the use of these to control a range of insect pests, both in Australia and overseas. His research on De/adenus siricidico/a alone is estimated to help protect Australia's pine forests from damage by sirex at between $1000 million and $4000 million in each rotation. His research and patents on entomopathogenic nematodes have enabled the establishment of a new export industry for Australia and resulted in major developments in insect control in China. Over the last eight years, Dr Bedding has gained four major awards and his research has attracted grants and royalty payments of over $3.5 million.
