Insects are the major component of the world's biodiversity. By their vast numbers of both species and individuals, they are vital determinants of the terrestrial ecological processes. Quantitatively, insects are important pointers for the species-rich geographical areas. Qualitatively, they are also important, whether the subjects of conservation themselves or as tools for identifying biotic areas with high endemism. "Insect Conservation Biology" covers a wide range of topics from single species to landscape conservation, and from rare butterflies to the benefits-and-risks of biocontrol agents. The approach is both positive and realistic, with insects being discussed in the contexts of sustainable development, agroecology and monitoring environmental change. Ethical issues surrounding insects are also considered as well as preservation technology and restoration ecology. Conservation circles have given too little attention to the ecological significance of insects, while entomologists have been employed mostly to control a tiny minority of species of insect pests. The realms of conservationist and entomologist are brought together in this book. This book should be of interest to conservation managers/biologists, entomologists, ecologists, and environmental scientists interested in biological diversity.
