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...

Probe into insecticide resistance needs grassroots input.. We are keen to map the geographical spread of the problem throughout Australia's cropping and pasture regions," Dr Umina says. ".. We also want to hear from landholders who have paddocks that have been subjected to heavy sprays in recent years so we can assess the insect pest populations to determine whether resistance is building or not, and if growers or advisers know of a paddock with control failures in the past, they are also encouraged to make contact."..

We are keen to map the geographical spread of the problem throughout Australia's cropping and pasture regions," Dr Umina says. ".. We want to hear from anyone who has experienced problems with insect pests which appear to have some resistance to insecticide," said Dr Arthur, who is particularly interested in resistance in mites and aphids. ".. We also want to hear from landholders who have paddocks that have been subjected to heavy sprays in recent years so we can assess the insect pest populations to determine whether resistance is building or not, and if growers or advisers know of a paddock with control failures in the past, they are also encouraged to make contact."..

Growers to help detect insecticide resistance.. "Resistance has been detected recently for the first time in a number of important species," Dr Arthur says... University of Melbourne entomologist Dr Paul Umina says information from growers and advisers is needed to develop management strategies, which require understanding of the tendency for resistance to spread and its frequency in southern cropping and pasture areas...
