This new book, Insect Diversity and Ecosystem Services, published in two comprehensive volumes, is an innovative work on insects and their impact on the ecosystem, describing their enormous free ecosystem services. The volumes cover a range of topics related to insects including their role in environmental pollution, their use in sustainable agricultural services, and the industrial, forensic, and medical applications of insects and their pure products. The book also covers the entomological and molecular aspects of insects, identifies the gaps in the research, and looks at integrated management strategies for pests.

The first volume, Volume 1: Importance, Threats, Conservation, and Economic Perspectives, presents a comprehensive review of different insect orders regarding their diversity and importance in providing free ecological services. This book discusses the different diversity patterns of biogeographic zones of the world and how insects contribute to maintaining ecological diversity in different biogeographic regions of the world.

Volume 2: Environmental Indicators, Molecular Approaches, and Management Strategies discusses the various aspects of insects, such as their role as environmental indicators, the effect of pesticides on insect diversity, strategies to control the diversity of insects, medical and forensic importance of insects, exploring new insect species through DNA barcoding, integrated pest management, the role of insect population in agriculture, and eco-friendly pest management approaches.

Some topics covered in the book include:

• Role of insects for sustainable agricultural development
• Commercial importance of insects and their products
• Food additive roles of insects and formulation of remedies for the reduction of disease pathogenesis
• Management strategies for pest control

Some specific topics include colony collapse disorder of managed honey bee (Apis mellifera l.) populations, insects as strong crime indicator tools in forensic sciences, insect-based value-added products, and more.

Together, these two volumes offer important information for researchers, academicians, scientists, industrialists, teachers, entomologists, and students for understanding the contribution of insects towards the sustainability of the ecosystem.
