Insects represent over half of all biological diversity. They pervade terrestrial and freshwater ecosystems, functioning as carnivores, herbivores and detritivores. Their ecology is of crucial economic importance to our planet and therefore ourselves - as pests of our crops, vectors of diseases, as beneficials in food webs, pollination and biological control. This textbook strikes a balance between theory and practice and between pure and applied ecology. In presenting the basic themes of insect ecology, it provides a sound background in evolutionary ecology, population dynamics and environmental interactions. These concepts are subsequently applied to a number of topical issues including climate change, the conservation of biodiversity, epidemiology and pest management. Based on a wealth of international teaching expertise, Ecology of Insects is aimed a undergraduate and postgraduate students taking courses in insect ecology and ap0plied entomology, as well as wider degree programmes in biology, general ecology, zoology, forestry and agriculture.
