Effect of Climate Change on Introduced and Native Agricultural Invasive Insect Pests in Europe

SIMPLE SUMMARY: Invasive insects, along with climate change, are among the two most important environmental problems facing the world today. They pose a threat to many ecosystems worldwide, especially agriculture. As a result, there is a serious risk of economic losses to crops and a challenge to human food security. The aim of this review is to examine the relationship between climate change and the process of invasion of economically important insects in Europe. In recent decades, globalization has led to an increase in the worldwide movement of people and goods, resulting in an increase in the number of insects introduced into areas outside their original range. The harmful effects of invasive insects may be exacerbated by climate change as barriers to their successful establishment and dispersal decrease. To limit economic and environmental damage, it is important to understand the biotic and abiotic factors that influence the process of insect invasion in the context of climate change. We highlight the main biotic factors that influence the biological invasion process. Finally, we present the adaptive management strategies for invasion of non-native insect pests’ invasion that include prevention, eradication and assessment of biological invasion in the form of predictive modelling. ABSTRACT: Climate change and invasive species are major environmental issues facing the world today. They represent the major threats for various types of ecosystems worldwide, mainly managed ecosystems such as agriculture. This study aims to examine the link between climate change and the biological invasion of insect pest species. Increased international trade systems and human mobility have led to increasing introduction rates of invasive insects while climate change could decrease barriers for their establishment and distribution. To mitigate environmental and economic damage it is important to understand the biotic and abiotic factors affecting the process of invasion (transport, introduction, establishment, and dispersal) in terms of climate change. We highlight the major biotic factors affecting the biological invasion process: diet breadth, phenological plasticity, and lifecycle strategies. Finally, we present alien insect pest invasion management that includes prevention, eradication, and assessment of the biological invasion in the form of modelling prediction tools.
