Adaptive pest management for horticulture under climate change – pilot pest scoping (VG13029)
What was it all about?
Climate change and climate variability are expected to bring new challenges for pest management. This project used two case studies to examine the nature of likely changes and to identify the changes in management practices that might be needed in horticulture.
The two case studies the researchers used were silverleaf whitefly and diamondback moth. Both pests were modelled to explore how their impacts might change under climate change scenarios, to find any vulnerabilities that could be addressed with strategies.
Modelling showed that both pests could increase the number of lifecycles they can complete each year by approximately 50 per cent.
The researchers suggested that the best strategy for modelling pest impacts under climate change would be to make periodic analyses of pests every five years. This could be a cost‐effective means to help alert pest management consultants to long term changes in pest dynamics.
