GRDC Calls for Insecticide Resistance Grassroots Input

June 8, 2012

Entomologists engaged in research projects funded by the Grains Research and Development Corporation (GRDC) are searching for locations where growers have experienced chemical control difficulties or failures when dealing with insect pests, particularly mites and aphids. The Grains Research and Development Corporation (GRDC) has issued a call to farmers and farm technicians to assist them in an ongoing investigation to identify areas at risk of having insecticide resistance and provide early detection of resistant populations.

The research is being led by cesar, a science-based company that delivers environmentally sustainable management solutions in agricultural pest control and wildlife conservation, and the University of Melbourne, in collaboration with entomologists across Australia.

"Entomologists suspect that the problem is more extensive than has been scientifically confirmed. We are therefore keen to map the geographical spread of the problem throughout Australia's cropping and pasture regions," says Dr. Paul Umina of cesar. The researchers also want to monitor paddocks that have been subjected to heavy sprays to assess build up of insect pest populations.
