Summary

This project focuses on identifying the characteristics of pest suppressive landscapes and adopts a national approach. To understand how the population dynamics of grain pests are affected by landscape composition we will (i) identify source habitats of pests and natural enemies, (ii) assess their movement between habitats and (iii) determine time of crop colonization. The habitats studied will include crop and non-crop such as native remnant vegetation. This work will be conducted in agricultural landscapes in north, south and west Australia. Spatially explicit models will be developed that integrate field data collected in each landscape. These models will be used to explore the links between crop and non-crop habitats and which landscape configurations are less prone to pest attack. This approach allows us to develop guiding principles of IPM at the field, farm and landscape scale which work towards achieving reduced reliance on broad-spectrum insecticides and sustainable management of natural resources.

Outcomes

This combined empirical and modelling approach allows us to provide guidelines on IPM at the field, farm and landscape scale.

Research

To understand how the population dynamics of grain pests are affected by landscape composition we will (i) identify reproduction habitats of pests and natural enemies, (ii) assess their movement between habitats and (iii) time of crop colonization. This work will be conducted in agricultural landscapes in north, south and west Australia. Spatially explicit models will be developed that integrate the results of field measurements. These models will be used to explore which landscape configurations are less prone to pest attack and evaluate the effectiveness of IPM options in various landscapes.

Native remnant vegetation can support beneficial predatory insects. Pest suppressive landscapes are those that have the right mix of habitats that support beneficial insects and allow them to move into crop fields, while discouraging the build-up of pest insect species.
