An introduction to the intriguing world of insects, from bullet ants to butterflies. Designed as an introduction to the intriguing world of insect biology, this book examines familiar entomological topics in nontraditional ways. Author David B. Rivers gives important concepts relatable context through a pop culture lens, and he covers subjects that are not typical for entomology textbooks, including the impact of insects on the human condition, the sex lives of insects, why insects are phat but not fat, forensic entomology, and the threats that some insects pose to humanity. Each chapter presents clear and concise key concepts, chapter reviews, review questions following Bloom’s taxonomy of learning, web links to videos and other resources, and breakout boxes (called Fly Spots) that capture student interest with unique and entertaining facts related to entomology. Focusing on both traditional and cutting-edge aspects of insect biology and packed with extensive learning resources, Insects covers a wide range of topics suitable for life science majors, as well as non-science students, including: • the positive and negative influences of insects on everyday human life • insect abundance • insect classification (here presented in the context of social media) • insect feeding, communication, defense, and sex • how insects are responding to climate change • forensic entomology • how insects can be used as weapons of war • how insects relate to national security • why insects have wings • how to read pesticide labels

Low temperature is a major environmental constraint impacting the geographic distribution and seasonal activity patterns of insects. Written for academic researchers in environmental physiology and entomology, this book explores the physiological and molecular mechanisms that enable insects to cope with a cold environment and places these findings into an evolutionary and ecological context. An introductory chapter provides a primer on insect cold tolerance and subsequent chapters in the first section discuss the organismal, cellular and molecular responses that allow insects to survive in the cold despite their, at best, limited ability to regulate their own body temperature. The second section, highlighting the evolutionary and macrophysiological responses to low temperature, is especially relevant for understanding the impact of global climate change on insect systems. A final section translates the knowledge gained from the rest of the book into practical applications including cryopreservation and the augmentation of pest management strategies.

Insects represent over half of the planet’s biological diversity. This popular textbook provides a comprehensive introduction to this extraordinary diversity, and places entomology central to the theory and practice of evolutionary and ecological studies. Fully revised, this fifth edition opens with a chapter concerning the popular side of insect studies, including insects in citizen science, zoos and butterfly houses, and insects as food for humans and animals. Key features of insect structure, function, behaviour, ecology and classification are integrated with appropriate molecular studies. Much of the book is organized around major biological themes: living on the ground, in water, on plants, in colonies, and as predators, parasites/parasitoids and prey insects. A strong evolutionary theme is maintained throughout. There is major revision to the chapter on systematics and a new chapter, Insects in a Changing World, includes insect responses to, and the consequences of, both climate change and human-assisted global alterations to distributions. Updated ‘Taxoboxes’ demonstrate topical issues and provide concise information on all aspects of each of the 28 major groupings (orders) of insects, plus the three orders of non-insect hexapods. New boxes describe a worrying increase in insect threats to landscape and commercial trees (including eucalypts, palms and coffee) and explain the value of genetic data, including evolutionary developmental biology and DNA barcoding, in insect biodiversity studies. The authors maintain the clarity and conciseness of earlier editions, and extend the profuse illustrations with new hand-drawn figures. Over 50 colour photographs, together with the informative text and an accompanying website with links to video clips, appendices, textboxes and further reading lists, encourage a deeper scientific study of insects. The book is intended as the principal text for students studying entomology, as well as a reference text for undergraduate and graduate courses in the fields of ecology, agriculture, fisheries and forestry, palaeontology, zoology, and medical and veterinary science.

Insect Biology in the Future: ""VBW 80"" contains essays presented to Sir Vincent Wigglesworth during his 80th year. Wigglesworth is fairly designated as the founding father and remarkable leader of insect physiology. His papers and other works significantly contribute to this field of study. This book, dedicated to him, underlines the value of insect material in approaching a wide spectrum of biological issues. The essays in this book tackle the insects' physiology, including their evolution and dominance. The papers also discuss the various avenues of water loss and gain as interrelated components of overall water balance in land arthropods. This reference suggests possible areas for further research mainly at the whole animal level. It also describes the fat body, hemolymph, endocrine control of vitellogenin synthesis, reproduction, growth, hormones, chemistry, defense, and survival of insects. Other topics of importance include cell communication and pattern formation in insects; plant-insect interaction; and insecticides.

Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
