Forest Microbiology: Tree Diseases and Pests, Volume Three in the Forest Microbiology series, provides an overview of major disease agents of trees, including viruses, phytoplasma, bacteria, fungi, nematodes and major insect pests. With a strong emphasis on genetics, biochemistry, physiology, evolutionary biology and population dynamics of the organisms involved, this book provides a comprehensive understanding on the health of forests. Sections cover important pest threats such as bark beetles, emerald ash borer, coffee borers, leaf cutting ants, cocoa mirids, and more. This volume highlights a range of emerging diseases of forest trees in temperate and tropic regions as well as information on habitats. Forest trees play crucial roles not only for mitigating effects of the climate change but also for their considerable economic and ecological value. Forest trees are equally vital as an alternative bioenergy source and play important roles in pollution abatement and the maintenance of biodiversity. Timber and its associated products from forest trees contribute substantially to the revenue generation of many countries of the world.

Dr Asiegbu has been the professor of forest pathology at the University of Helsinki since 2007. He has a master’s degree in applied microbiology and plant pathology, and a PhD in biotechnology. His major research focus has been the application of biotechnology knowledge and tools for the determination of ecological, molecular and biochemical pathways required by emerging fungal and forest pathogens to spread, infect and cause disease to trees worldwide. He has been a member of the faculty interdisciplinary Master's Programme in Biotechnology and is also an invited professor at Nanjing Forestry University in China. Dr Kovalchuk is a researcher at the University of Helsinki. He has a PhD in molecular biology and has over 30 peer-reviewed journal publications on forest microbiomes.
