This chapter examines how factors involved in climate change have direct and indirect effects on the chemical defences of plants. It looks at how these changes are reflected in the chemical communication between trophic levels and how the changes at lower levels might be accumulated and reflected in the ecology of species at higher trophic levels. It also presents examples from tritrophic systems, which are frequently studied and used as model systems, to estimate the impacts of environmental disturbance on the components of chemical tritrophic communication between plants, herbivores and parasitoids. The chapter especially focuses on the impacts of oxidative pollutants such as ozone, elevated CO2, and rising temperature on the atmospheric behaviour of volatile signalling compounds, which are particularly important in parasitoid host location – a significant stage for determining parasitoid success, reproduction, and population development.
