Grain growers can use a testing service to determine if insecticide resistance exists in redlegged earth mites on their properties... Growers in the southern grains region are encouraged to use a free redlegged earth mite (RLEM) insecticide-resistance testing service made possible through a national GRDC-funded project led by the University of Melbourne, in collaboration with cesar , the Department of Agriculture and Food, Western Australia (DAFWA), CSIRO and the University of WA... Resistance to synthetic pyrethroids (SPs) is already confirmed in large populations of RLEM across the WA grainbelt, while some populations in WA also have resistance to organophosphates (OPs)...

Research delves into growing issue of insecticide resistance Insecticide resistance in several broad-acre agricultural pests across southern Australia is being investigated through a research project supported by the Grains Research and Development Corporation (GRDC)... For example, insecticide resistance in redlegged earth mites to synthetic pyrethroids was first discovered in Australia only a few years ago on a property in Western Australia, and since then this resistance has spread across 15 different properties, spanning a distance of 450.. Dr Umina said that to develop management strategies aimed at limiting the widespread development of resistance in these pests, a better understanding of the spread and frequency of insecticide resistance throughout cropping and pasture regions across southern Australia was needed...

Mitey useful service to check for insecticide resistance.. The season, grain growers in the southern cropping region can access a free-of-charge service to determine whether redlegged earth mite (RLEM) populations within their crops are resistant to insecticides... The RLEM insecticide-resistance testing service is being made available to growers and their advisers through a national Grains Research and Development Corporation-funded project led by the University of Melbourne in collaboration with cesar , the Department of Agriculture and Food, Western Australia (DAFWA), CSIRO and the University of WA...

The Grains Pest Advisory Committee (GPAC) has formed a National Insecticide Resistance Management working group to develop new strategies for managing insecticide resistance in grains pests... Costly pests that already exhibit insecticide resistance include green peach aphid, cotton bollworm ( Helicoverpa armigera ), redlegged earth mite, diamondback moth and silverleaf whitefly... GPAC was established by the GRDC in 2013 to provide expert advice on the changing pest scene and its management...

Photograph showing a row of Helicoverpa coloured larvae in lucerne.. Crop damage by H. armigera is most common during the later part of the summer season... The basic principles of the strategy involve a yearly cycle of management practices, which includes tactics that aim to reduce: the population of overwintering Helicoverpa pupae (March-June) the early season build-up of Helicoverpa on a regional/district scale (July-November) the mid-season population pressure on Helicoverpa- sensitive crops (December-March)...

Destroying the green bridge of weeds and volunteer crops during summer is a key tactic for reducing aphid and virus risks to canola plantings in 2016... Weeds such as wild radish, wild turnip and marshmallow and volunteer canola plants can host big populations of insects, including aphid vectors for viruses, and should be controlled in the lead-up to sowing... Dr Paul Umina, of cesar and The University of Melbourne, said western region growers should particularly monitor infestations of green peach aphids (GPA - Myzus persicae ) in coming months, especially after significant rainfall events...
