Climate change and food security

In this post, Adam Frew discusses his paper ‘Increased root herbivory under elevated atmospheric carbon dioxide concentrations is reversed by silicon-based plant defences‘ As the global climate changes the global population continues to rise, we are faced with the daunting challenge of achieving sustainable crop production to meet the increasing demand for food. Professor John Beddington in 2009, UK chief scientist at the time, highlighted … Continue reading Climate change and food security

Fatal attraction of Spotted Wing Drosophila to a yeast symbiont, for sustainable control

In this blog post Joelle Lemmen, Alix Whitener, Boyd Mori and Peter Witzgall discuss the recent paper by Boyd Mori and colleagues ‘Enhanced yeast feeding following mating facilitates control of the invasive fruit pest Drosophila suzukii‘ Spotted Wing Drosophila (SWD) is currently the most economically important insect in Europe and North America. SWD damages a wide range of our favourite berries and soft fruit, including … Continue reading Fatal attraction of Spotted Wing Drosophila to a yeast symbiont, for sustainable control

Bark beetle impacts on ecosystems and society

In this post Jesse Morris discusses his research, published today in Journal of Applied Ecology ‘Managing bark beetle impacts on ecosystems and society: priority questions to motivate future research‘ Forests provide many goods and services that have ecological, economic, and social value. Management agencies and scientists often refer to these benefits as ecosystem services. Some examples of ecosystem services include purifying air, controlling water runoff … Continue reading Bark beetle impacts on ecosystems and society

Avian pest control in vineyards

In this post Michelle Harrison and Cristina Banks-Leite discuss a recent paper by Luc Barbaro and colleagues ‘Avian pest control in vineyards is driven by interactions between bird functional diversity and landscape heterogeneity‘. The global wine industry currently contributes roughly US$303 billion to the world’s economy (Plant and Food Research, 2013). Wine is a key export for many European countries such as Italy, France and … Continue reading Avian pest control in vineyards

Adapting to realistic constraints of eradications: an ‘action-portfolio’ framework that improves ecological benefit and reduces cost

This post by Melissa Wynn, discusses the recent paper by Kate Helmstedt, Justine Shaw, Michael Bode, Aleks Terauds, Keith Springer, Susan Robinson and Hugh Possingham ‘Prioritizing eradication actions on islands: it’s not all or nothing‘ Melissa is a PhD Candidate in the Fenner School of Environment and Society, at the Australian National University, (Twitter: @melissalwynn) One of the greatest threats facing Australia’s unique fauna today … Continue reading Adapting to realistic constraints of eradications: an ‘action-portfolio’ framework that improves ecological benefit and reduces cost

The ecology behind mosquito–Wolbachia interactions: implications for a novel strategy for biocontrol of arboviruses

In this post Penelope Hancock discusses her paper ‘Density-dependent population dynamics in Aedes aegypti slow the spread of wMel Wolbachia‘ published in Issue 53:3 today. Aedes aegypti mosquitoes, the primary vector of dengue and zika, are the current target of a novel biocontrol strategy involving Wolbachia bacteria. Mosquitoes infected with Wolbachia are less able to transmit viruses to humans. Releases of Wolbachia bacteria into field … Continue reading The ecology behind mosquito–Wolbachia interactions: implications for a novel strategy for biocontrol of arboviruses

Flower strips support ecosystem services only when they have the right flowers

In this post Paul van Rijn discusses his recent paper ‘Nectar accessibility determines fitness, flower choice and abundance of hoverflies that provide natural pest control’ The industrialization of agriculture has strongly impoverished our countryside. The amount and quality of non-crop habitats have declined, and the biodiversity within and among crops has dropped even more. In recent years it has become clear that this not only … Continue reading Flower strips support ecosystem services only when they have the right flowers

Natural vegetation and biocontrol in southern Africa

In this post Dominic Henri discusses his recent paper ‘Natural vegetation benefits synergistic control of the three main insect and pathogen pests of a fruit crop in southern Africa‘ You can also find a poster ‘Distance-dependent natural vegetation benefits to the biocontrol of multiple pests and pathogens in South Africa mango farms’ associated with the paper here. It is a widely held view among the … Continue reading Natural vegetation and biocontrol in southern Africa
