Climate Change and Insect Pests
Insects, being poikilothermic, are among the organisms that are most likely to respond to changes in climate, particularly increased temperatures. Range expansions into new areas, further north and to higher elevations, are already well documented, as are physiological and phenological responses. It is anticipated that the damage by insects will increase as a consequence of climate change, i.e. increasing temperatures primarily. However, the evidence in support of this common “belief” is sparse. Climate Change and Insect Pests sums up present knowledge regarding both agricultural and forest insect pests and climate change in order to identify future research directions.
Scientific Review of the Impact of Climate Change on Plant Pests
This study warns that climate change may increase the risk of pests being introduced to new areas. It recommends conducting pest risk analyses and strengthening international cooperation as preventive measures to protect plant health.
Climate-change impacts on plant pests: a technical resource to support national and regional plant protection organizations
Climate change is having an impact on ecosystems and agricultural production systems throughout the world. It influences international trade flows of plants and plant products and it will change the infectivity, severity and distribution of plant pests throughout the world. Preventive, mitigation and adaptation measures by national plant protection organizations (NPPOs) and regional plant protection organizations (RPPOs) are essential to limit the international spread of pests adapting to climate change.Climate-change impacts on ecosystems, pests and vectors also threaten the international trading system, as international trade provides a pathway for pests and vectors to spread into new areas of the world. To facilitate safe international trade in plants and plant products, it is therefore imperative to strengthen national, regional and international phytosanitary capacities regarding climate change. The aim of this document is to provide technical and operational advice to NPPOs and RPPOs on how to effectively assess and manage the pest risk that is a consequence of climate change.
