The findings are from a nationally coordinated project supported by the Grains Research and Development Corporation (GRDC) which aims to understand which landscape features contribute to the control of pest populations in crops... "Remnant bushland containing few weeds may reduce the number of pest species and at least delay the build-up of pests in crops during the growing season," she said... She is now using computer simulations of landscapes to understand which management practices - within crops and pastures as well as native vegetation - affect pest populations by encouraging beneficial insects or reducing sources of pests...

The majority of insect species present in these landscapes, especially pests, are good at moving between these habitats and seeking out the resources they need, such as food and shelter for all or part of the year... There is a strong interest in developing integrated pest management (iPm) on a large scale because pests are mobile... Pest suppressive landscapes will have the right mix of habitats that support beneficial insects and allow them to move into crop fields, but discourage the build-up of pests...

The findings are from a nationally coordinated project supported by the Grains Research and Development Corporation (GRDC) which aims to understand which landscape features contribute to the control of pest populations in crops... Ms Micic said that data taken from remnant vegetation in WA showed that insect pests were more likely to be found on weeds, while beneficial species were more likely to be found on native plant species...

Repeated insecticide application keeps increasing the proportion of resistant individuals in a pest population until the majority are resistant to that insecticide... Before deciding to spray crops at tillering, flowering or podding: identify pests and the densities at which they are present in the crop; determine if pest populations are increasing, static or declining; and determine if beneficial insects such as parasitic wasps and ladybird beetles are present... Slug numbers can be estimated by laying a series of carpet squares or large tiles on page 4 the ground with baits underneath...

In cropping systems relatively few insect species represent a significant threat to crop yield or are classified as pest species... Beneficial insects and other invertebrates ("beneficials") offer a variety of ecosystem services that are essential within agricultural environments and it is important to conserve and promote them as far as is practical within the constraints of controlling for major crop pests... Agriculture, by definition, manipulates the environment - we are providing large areas of a uniform resource for pest insects to thrive on...

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...

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."..
