Synthetic pesticides in AgroEcosystems

This research examines the effects of broad-spectrum and several selective ‘softer’ pesticides on pest and non-target invertebrates in Wheat and Canola crops in southern Australia between 2008 and 2010. This article discusses the notion that broad-spectrum pesticides negatively effect non-target and potentially beneficial invertebrates more than selective pesticides. In this study, limited effects on non-target groups were detected, and instances where broad-spectrum pesticides had negative effects, these effects varied between sites and non-target groups. The implications of these results are discussed.

This article investigates how habitat types in agricultural landscapes affect the reproduction of both pest and their natural predators. This was examined by looking at the species present in six crops and the seven most abundant native plants in two landscapes over the course of a year. The authors found that native plants and crops supported different assemblages, with native vegetation  possessing higher densities of predators and crops supporting higher pest numbers. This research suggests that the maintenance or restoration of native vegetation can increase predator numbers, enhancing the suppresion of pest in crops.

This article uses old survey data collected on the location of red legged earth mites across Australia and compares it to newer surveys including its native range in South Africa. Despite being introduced into Australia relatively recently (in the 1960’s) this species seems to being doing well under Australian conditions and is now capable of surviving in  hotter and drier inland areas.

This review examines effective pest management in coarse grain cropping and discusses the reasons for the lack of implementation of IPM principles by growers despite the industries desires. The authors argue that with increasingly limiting climatic conditions and increasing demand for coarse grain, a widely adopted, dymanic approach to IPM can provide a low cost control of invertebrate pests with reduced environmental impacts.

This article examines the movement of pests and their natural enemies between the crop-crop and native vegetation-crop interfaces. The differences in movement of pests and their natural enemies across these edge types and their impact on pest control services are discussed.

This article provides an overview of IPM in the major grain crops of north-eastern Australia, north of latitude 32oS. The benefit of IPM to grain crops, IPM tools and strategies for the use of insecticides, biopesticides and parasitoids, and the future directions in IPM, are all discussed.

This article discusses the shift in invertebrate pests due to evolving management practices and climate change over the last 20-30 years in the Australian grains industry. Changes in pest pressure,  pesticide usage, changed farming practices and climate changes as drivers, the potential impacts of GM crops and the future of IPM are also discussed.

Predator and parasitoids can make significant contributions to the suppression of insect pest populations in cropping systems. This article reviews the role that natural enemies play in the suppression of major pests of grain crops within Australia and describes possible methods to determine the impact of these interactions.
