This chapter investigates the complex challenges of using introduced insects for weed biocontrol in the context of climate change. It explores how changing climatic factors, such as temperature, precipitation and CO2 levels, affect the physiology, behaviour and ecological interactions of both invasive plants and their biological control agents (BCAs). These changes can greatly impact the effectiveness and safety of biocontrol efforts. This chapter emphasizes the need to integrate evolutionary biology with ecological modelling to accurately predict and manage these impacts. Additionally, it addresses the potential for non-target impacts resulting from altered habitats and phenological overlaps caused by climate change. By proposing interdisciplinary strategies, this chapter offers a framework for developing sustainable, eco-friendly biocontrol methods as traditional chemical approaches become less viable. This synthesis of current research is crucial for those seeking to improve weed management practices in the context of global climate change and the One Health concept.
