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...

Research reveals extensive aphid insecticide resistance.. Researchers have discovered that the extent of insecticide resistance in populations of the green peach aphid (GPA) has escalated across Australia... "If we discover that individual aphids have resistance to organophosphates, synthetic pyrethroids and carbamates, it will mean the likely reproduction of fully resistant offspring (GPA can reproduce asexually to produce clones of themselves) and will have significant implications for the ability of growers to control GPA in their crops."..
