Less aphids are found flying in crops close to native vegetation.. Aphids can vector viruses that lead to yield loss in crops eg BYDV in cereals can decrease crop yields by 50%if plants are infected prior to tillering; or cause direct feeding damage which can cause yield losses of up to 10% in cereals (DAFWA 2007)... Significantly more (p<0.001) brassica aphids were found in traps that were close to native vegetation whereas traps that were far from native vegetation had significantly (p>0.001) higher numbers of legume aphids and aphids whose hosts were unknown...

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 importance of protecting remnant vegetation is now enshrined in land clearing regulation and there is also a growing recognition that native vegetation can support ecosystem services that provide benefits to agricultural production... The projected movement of high intensity cropping into new bio-regions in the HRZ is likely to challenge valuable biodiversity assets that currently exist in these areas... Finally approaches for integrating cropping into the HRZ that maximise biodiversity conservation and ecosystem service benefits will be developed...

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...

Native vegetation in grain-cropping landscapes can provide a habitat for beneficial predatory insects, supporting overall pest-control programs... Pastures, especially weedy pastures, provide habitat for pests.. Native vegetation, particularly remnant natural bush, provides a haven and natural food source for beneficial insects, which prey on exotic insects attracted to grain crops and also to many weed species...

Patches of native vegetation in cropping landscapes are important for attracting beneficial insects into crop fields early in the season... According to research documented in the Grains Research and Development Corporation (GRDC) fact sheet Pest Management Using Native Vegetation, weedy pastures are found to play a key role in providing habitat for pests, while native plants are more conducive to predators...
