My work
focuses on the development of biological indicators to assess the effects of
management practices on invertebrates in agriculture, especially vineyards,
specifically, beneficial organisms such as contributors to pest control and
soil health. Populations of beneficials such as predatory and parasitoid flies
and wasps, predatory mites, lacewings, native earwigs and beetles reduce the
occurrence of pest species, while earthworms and springtails improve soil
quality.
Current Research:
Sustainable viticulture 2010 and beyond. Vineyardmanagement to maximise beneficial invertebrates to increase the bottom line.
The influence of spiders in biocontrol of Ephiphyas postvittana (Walker) (Lepidoptera: Torticidae) in vineyards.
Industry Tools:
Collateral Management in Vineyards Database and Toxicity Calculator.
