This text considers forest insects occurring in forest ecosystems, specialized forestry settings, and urban forests, with an approach and coverage that make it suitable for use in both undergraduate and graduate courses in forest entomology and forest protection. Early chapters introduce entomology, middle chapters provide the first comprehensive treatment of the principles of Integrated Pest Management (IPM) of forest insects, and later chapters discuss the pest insects according to their feeding group.

The Role of Insectivorous Birds in Forest Ecosystems is a publication of the proceedings of The Role of Insectivorous Birds in Forest Ecosystems symposium, held on July 13 and 14, 1978 at Nacogdoches, Texas. The proceedings discuss the ecology of insectivorous birds and acknowledge their roles in forest ecosystems. The book begins with an introduction to and history of insectivorous birds and their roles in forest ecosystems. It then discusses the sampling methods for bird and insect populations, bird foraging strategies, and ecology of insectivorous bird species and communities. This book will be helpful to forest managers in managing insectivorous birds. It is also especially valuable in formulating biological control strategies for use in forests.

This open access book will provide an introduction to forest entomology, the principles and techniques of forest insect pest management, the different forest insect guilds/feeding groups, and relevant forest insect pest management case studies. In addition to covering 30% of the earth, forest ecosystems provide numerous timber and non-timber products that affect our daily lives and recreational opportunities, habitat for diverse animal communities, watershed protection, play critical roles in the water cycle, and mitigate soil erosion and global warming. In addition to being the most abundant organisms in forest ecosystems, insects perform numerous functions in forests, many of which are beneficial and critical to forest health. Conversely, some insects damage and/or kill trees and reduce the capacity of forests to provide desired ecosystem services. The target audience of this book is upper-level undergraduate and graduate students and professionals interested in forest health and entomology.

Rapid depletion and degradation of species in diverse ecosystems and the implications of this for human welfare have the cause for increasing concern. Biodiversity or variability among living organisms and the ecological complexes of which they are a part, is essential for ensuring the basic ecological services and resources necessary for sustaining human welfare. The loss of biodiversity is therefore, considered one of the most serious problem threatening the world today. An understanding of the ecological implications of the increasing loss of bodiversity, not to mention of the economic implications, has therefore, became vital. A biodiversity loss is irreversible. A calls for increased caution in our efforts to convert and exploit natural resources. Some minimal level of biodiversity is necessary to main ecological functioning, which in turn is necessary for generating the biological resources on which human welfare depends. Needless to emphasive that substantial biodiversity loss occurs due to forest clearing and degradation, leading to the need for assessing biodiversity in different ecosystems. Keeping these aspects in mind, the present volume highlights biodiversity in different cropping systems besides that the impact of cold and hot deserts. Selection of the topics in the various chapters is essentially because of the experience of the authors in the field of biodiversity.

The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.

This book covers the full breadth of forest entomology. It combines the work of forest entomologists working on the impact and management of forest pests with those involved in diversity assessment and conservation of insects in forests. Forests and Insects demonstrates that both these disciplines demand an understanding of population and community biology. The book covers such topics as colonization of trees by insects, population dynamics of forest insects, insect natural enemies, the effects of climate change and pollution on forest pests, spatial variation in the abundance of insects,the mineralization of carbon by termites, the impact of herbivorous insects, and the conservation of forest insect diversity, including the effects of forest fragmentation and deforestation. This Royal Entomological Society Symposium volume will be of great interest to all agricultural and forest entomologists, population and community biologists, pest management specialists and anyone concerned with the conservation of forest biodiversity.
