Recent Advances in Insect Physiological Adaptations

Insects exhibit a range of physiological adaptations that contribute to their success in diverse habitats. Their exoskeleton provides protection from predators and dehydration. Many insects regulate their body temperature through behaviours like sunning themselves or seeking cooler areas, ensuring optimal metabolic function. Their respiratory system consists of tracheae that deliver oxygen directly to cells without the need for lungs, allowing efficient gas exchange even in small-bodied species. Insects possess specialised sensory organs like antennae for detecting chemicals and vibrations, and compound eyes that provide a wide field of vision for detecting movement and colours. Their ability to undergo metamorphosis enables them to exploit different food sources and habitats. These adaptations have allowed insects to occupy virtually every terrestrial and aquatic habitat, showcasing their adaptability and evolutionary success in ecological communities worldwide. This book includes some of the vital pieces of work being conducted across the world, on various topics related to insect physiological adaptations. It presents the complex subject of physiology and entomology in the most comprehensible and easy to understand language. With state-of-the-art inputs by acclaimed experts of this field, this book targets students and professionals.
