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...

With insecticide resistance increasing in the insect population of the northern cropping region, researchers are urging growers to take a closer look at integrated pest management (IPM) and avoid 'insurance' sprays... The Grains Research and Development Corporation (GRDC) has produced a new six-page publication containing the latest guidelines to reducing reliance on insecticides, limiting the opportunity for resistance and promoting populations of beneficial species... Dr Miles said any IPM measure that reduced the need to spray for helicoverpa also reduced the risk of it developing resistance to newer, more IPM-compatible insecticides...

Studies funded by the Grains Research and Development Corporation (GRDC) have found that the extent of insecticide resistance in GPA populations across Australia has escalated... With widespread resistance to synthetic pyrethroids, carbamates and organophosphates existing in Australia's mainland cropping regions, insect pest management experts say rotating chemical groups and taking advantage of biological control are essential to extend the useful life of available chemistries... Within Australia, GPA primarily reproduce asexually to produce clones of themselves and recent studies have shown that individual clones contain resistance to multiple chemical groups...

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."..

Management of SLW is complicated by the whitefly's capacity to feed on many different plant species and rapidly acquire insecticide resistance... Previous research indicated that Er... , host plants of the whitefly with low or no parasitism prior to the release have had an order of magnitude increase in levels of parasitism...

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...

Insecticide resistance in RLEM was first discovered in 2006... In the project, a range of possible 'soft' insecticides was assessed for efficacy against these pests... The results generated in this project provide a valuable framework to devise control strategies for several crop establishment pests and for prioritising future research...
